The Brightest LED Bulb Overall

The SANSI 65W LED Light Bulb is very bright, producing 10,000 lumens. Because it is a non-dimmable daylight-style bulb, it is probably best suited to garages and warehouses.

The Brightest “Warm White” LED Bulb

The SANSI 27W A21 Dimmable LED Light Bulb is a warm white bulb and produces 4000 lumens. I have one in the laundry room and it produces a very bright pleasing illumination. I wasn’t able to install it in a ceiling fan fixture, because it was slightly too large.

The Brightest Standard Size LED Bulb: Philips 5000 Lumen Bulb

The Philips 5000 LED Light Bulb is rated at 5000 lumens, making it the brightest standard-sized (A21) LED light bulb on the market. It uses 43 Watts and it has a 5000K color temperature (daylight white). It is suitable for outdoor areas and garages. If you need a warm white bulb for interiors, see the Philips bulb below.

The Brightest Standard Size Warm White LED Bulb

The Philips 100w Equivalent LED Bulb is another standard-size household bulb available. It uses 13.5 watts of power to produce 1500 lumens of warm white light. I have many of these in my home, and they produce excellent quality light (the CRI is 80). These bulbs are also dimmable and rated to last 22.8 years.

Bright LEDs: Few Notes On Color Quality

The Color Rendering Index (CRI) is a numerical system that rates the “color rendering” ability of light bulbs in comparison to natural daylight. If a light has a low color rendering index of 50, it does not render colors very well. If the lamp has a color rendering index of 80 – 95, which is very good to excellent.

The Color Temperature is expressed in Kelvin (K). Low color temperature implies warmer (more yellow/red) light while high color temperature implies a colder (more blue) light. Moreover, the “color temperature” of a lamp refers to how reddish, greenish, or bluish the lamp appears. If the lamp appears reddish, it has a lower color temperature (e.g., 2500K-3000K) and is considered to be “warm” in appearance. If the lamp appears to be bluish, it has a higher color temperature (e.g., 4000K-4500K) and is considered to be “cool” in appearance.

Warm White: 2500 K to 3000 K
Cool White: 4000 K to 4500 K
Daylight: 6200 K to 6800 K

Best Design: The Z-Bar Mini LED Desk Lamp

The slender Z-Bar High Power LED Desk Lamp features high-tech power-saving LED bulbs in a minimalist frame. With its angular black aluminum housing and unique pivot, it belongs on a Berlin engineer’s desk or in the lobby of an upscale New York architect.

The ingenious design extends beyond aesthetics; this is a seriously bright light that uses very little energy. The Z-Bar’s six daylight white LEDs generate about 240 lumens of light and only expends 9 watts of energy.

If 9 watts is still too much energy usage for your taste, activate the built-in 4-step dimming function to produce a softer light for even less wattage. This feature works incredibly well when you are unwinding prior to bedtime. Lower the light before you fall asleep to adjust your brain to get ready for bed.

The thin circular base is weighted to keep the light from tipping over, and adjustable joints can be placed in almost any position without tightening or loosening knobs or screws, simply move the light to where you need it and the lamp will hold to form.

The Z-Bar is the winner of I.D. Magazine “best of category” award. It is available on Amazon for around $300.

Best Overall: Lumiy Lightblade 1500S

If you find your desk lamp’s brightness underwhelming, buy a Lightblade and let there be light. This is the LED desk lamp for those who want only the brightest crispest replica of perfect natural light. With 1100 lux of brightness and a high CRI, the Lightblade can transform even the dreariest space into a warm and bright zone of productivity.

The Lightblade’s radiant lighting comes from its cool and warm white LED’s for a color rendering index of over 90 CRI. A light’s CRI determines its ability to accurately display an object’s full color. The higher the CRI, the more faithfully the color is displayed as if it would be in natural light. The Lightblade’s high CRI makes it a perfect choice for artists and other professionals who require brilliant vibrant colors.

The lamp has other desirable features, including an omnidirectional pivoting head for better control of the lighting. It also has touch sensors that control brightness and monitor energy expenditure.

The Lumiy Lightblade 1500S is available on Amazon for about $100.

Best Value: TaoTronics Smart LED Desk Lamp

The TaoTronics LED Desk Lamp is perfect for those who want bright light at an affordable price. 30 dollars gets you  410 lumens of power and up to 11 levels of brightness, perfect for any setting. The best feature of this lamp is its versatility. It includes 5 color modes, which function as temperatures that you can adjust depending on your need. The soft uniform light is ideal for reading and doesn’t flicker like other value options, while the natural light is perfect before bed. It also has an incredible lifespan. According to the manufacturer, this lamp is rated to last for 50,000 hours and uses 75% less energy than incandescent lights with similar brightness.

The Smart LED desk lamp also looks elegant.  An adjustable gooseneck gives further control over light positioning and brightness, while the blend of silver metal looks modern and can fit in any room. 

The TaoTronics LED Desk Lamp is available on Amazon for about $30.

Most Customizable: The Softech DL-90 Multi-Function LED Desk Lamp

Softech‘s latest LED desk lamp offers an astounding amount of customization for total brightness control. You decide the lighting mode you want and the DL-90 will conform to your request. The lamp has 27 high-power daylight LEDs with a 90+ CRI that comes extraordinarily close to natural light.

The lamp has four distinct lighting modes and 40 brightness levels in total for total precision. The first two modes are for desk work: a reading mode with mid-range colors (4300K-5300K) that are easy on the eyes, and a study mode which has a high range color temperature (6000K-7000K). The lamp can also be switched to a relaxation mode and a sleep mode — these have softer, warm color temperatures.

This lamp uses 10 watts or less of power to provide light equivalent to a 100-watt incandescent bulb. It lasts about 40,000 hours or 20 years of normal use. An automatic turn-off feature extends lamp life even further.

The Softech DL-90 lamp is available from Amazon for about $70.

Most Versatile: BYB E-430

Clamp-on desk lamps are a great option for those working who need high-quality illumination but are working with limited desk space. The award-winning design of BYB’s E-430 dimmable LED desk lamp delivers energy-efficient lighting from a slender device latched onto the side of your desk. It has a swivel lock socket that tilts in any direction, whether it’s on the desk or not. The adjustable arm is matched by a flexible head and includes built-in dimming strips.

It delivers 4 lighting modes and 6 levels of brightness, ranging from study mode to bedtime mode. We also like that the lamp is rated for 50,000 hours and comes with a 5-year warranty.

The BYB E-430 is available on Amazon for around $110.

Best Smart Design: TaoTronics TT-DL27 Desklamp

Take advantage of four distinct lighting modes with this versatile smart LED desk lamp from TaoTronics. You can set the lamp to sleep mode, study mode, reading mode, or relax mode, each delivering a customized LED distribution designed to satisfy your needs. And if study mode is likely to become sleep mode, you can just activate the 1-hour off timer on the lamp to make sure it shuts off as you drift to sleep.

I also enjoyed that you can swivel, rotate, and bend the head and neck of the lamp to fit your lighting needs. Just tilt the head to activate a wide 62cm2 area of light, enough to illuminate your entire desk area. The metal arm and sturdy base are hallmarks of great construction, making sure the light doesn’t fail on you.

The TaoTronics LED Desklamp is available for around $35.

The Details

It’s important to keep indoor humidity at an optimum level (45 to 65 percent). Dry air in the winter is one the main causes of sinus infections and sore throats. Dry air is also hard on the lungs and tends to cause dry skin.

The Venta Airwasher is a unique device that cleans and humidifies the air in your room by drawing air over a slowly rotating drum which is covered with water. This low-tech “cold evaporation” system is very efficient  — the Venta draws only seven watts on the highest setting.

I’ve been testing a Venta in my house for a couple of months now. It’s winter here, and the unit  has been running 24 hours a day on the second highest setting. On average it consumes about 1.5 gallon of water per day.

The Venta requires fewer refills than most humidifiers and fewer cleanings too. Most humidifiers require cleaning every third day, but the Venta requires a cleaning only every two weeks. In order to cut down on the cleanings, it relies on a proprietary chemical mixture. It comes with a two week supplies on the cleaning mixtures. For $20, you can purchase a 35 ounce replacement bottle that last four months.

The Venta Airwasher has a ten year warranty and each model is fully recyclable. It is manufactured in a facility powered entirely by wind energy in Germany.

The Venta Airwasher is available from Amazon for about $300.

Ultraviolet light is the preferred light source of TV crime scene investigators on the hunt for body fluids. Distinguished by its trademark purple glow, it has a wavelength that is shorter than visible light but longer than X-rays, in the range of 10 nanometers to 400 nanometers. It is useful to make fluorescent substances glow that can’t otherwise be seen by the naked eye. Portable UV light used to be too unwieldy and expensive for consumer purposes, but that all changed after ultraviolet light emitting LEDs were introduced in 2006. They are now widely available in flashlight form.

These flashlights are most often used to detect fraudulent documents such as fake IDs, see watermarks, read invisible ink or investigate crime scenes. They can also be used to “fluoresce” scorpions and certain types of minerals, and charge “glow-in-the-dark” object like fishing lures. Use them to protect your businesses from counterfeit money and your home from pointy tailed pests.

Gallium Indium Nitride UV Flashlight

This Gallium Indium Nitride UV flashlight gets great ratings from Amazon buyers, so we thought we’d include it here. Reviewers were impressed by the flashlight’s durability, and the fact that it emits 365 nm UV light, which is at the very edge of our visible range. The light from this flashlight appears as a dim purple-blue to the eye, but when it shines on items that fluoresce they light up brightly.

It uses three AAA batteries — we recommend using low self-discharge AAA rechargeable batteries like Eneloop Pros in this flashlight.

Here are some reliable speaker dock that still allow you to dock your iPad and immediately play your music:

Sony RDPXF300IPN Lightning iPad Dock

The Sony RDPXF300IPN Lightning iPad Dock is the best sounding speaker dock I’ve tested. The two speakers output 20 watts each, and have a rich and bright sound. In fact, this dock sounds better than the Bose SoundDock Series III (which also lacks bluetooth connectivity and a remote control).

This dock has an internal lithium-ion battery so it can be used as a portable player, it also features a radio and a remote control.

The Sony RDPXF300IPN Lightning iPad Dock is available from Amazon for about $300.

iHome iDL48BC Dual Charging Portable Rechargeable Speaker

The iHome iDL48BC speaker dock is a good budget choice for a speaker dock. It delivers resasonably good sound, but it lacks some of the clarity and bass of the Sony RDPXF300IPN.

The iHome iDL48BC is available from Amazon for about $80.

Definitive Technology’s SuperCube III produces unbelievable bass despite its compact footprint. Its sound profile is defined by its extreme depth—all the way down to 16Hz. The SuperCube III produces an authoritative 650 watts of power, capable of handling the bass duties in small or large rooms. Listeners appreciate the SuperCube III’s versatility; it performs as well when asked to provide a steady, undistorted rumble as it does when the soundtrack demands rapid, staccato bursts of bass. Though this gloss black cube weights a substantial 25 pounds, it only measures 10-1/4 inches in any dimension. It has a signal-sensing auto on/off switch, low-pass crossover, volume control, 5-way binding post outputs, and line level, LFE, and 5-way binding post inputs. Its woofer is 7-1/2 inches in diameter.

• The best projector for businesses with large, bright conference rooms is the BenQ MH741 Projector. It is incredibly bright at 4000 lumens and has true HD image quality.
• The best projector for small businesses is the Epson PowerLite 580. It is an ultra-short-throw projector that can cast a 93″ image from as little as a foot away, perfect for cozy offices.
• The best portable projector for business travelers is the iCODIS CB-300. It is handheld with an internal battery, and is equipped with a host of connectivity options to streamline presentations.

The Details

Whether you want to dazzle investors with a multi-media pitch or get the new hires up to speed on the intricacies of HR policy, a projector is a key tool for businesses of every size and industry.

No two businesses are the same, so every company needs to keep a few factors in mind when choosing a projector. Here are a few things to keep in mind when deciding which projector is right for you.

Businesses want bright projectors, and the brightness of a projector is determined by the number of lumens. Home theatres can get away with low lumen counts because they are in rooms with low ambient lighting. Offices have glass windows and don’t want to turn out the lights and draw the blinds every time a projector turns on. That means businesses should stay away from the legion of LED projectors that have appeared on the market in recent years. While cheaper than 3LCD and DLP options, most LED projectors don’t hit the 2500 lumen minimum most offices require. Of course, if your office is dungeon-like and you are fine with presenting sans illumination, you can sacrifice a few lumens.

The next thing to keep in mind is picture quality, which is determined by the resolution, or number of pixels on the screen. High resolution gives a higher picture quality and sharper image. This doesn’t matter much if your projector isn’t going to be casting anything more glamorous than excel spreadsheets and powerpoint presentations, but it makes a huge difference for any graphic design elements or videos. This mean you want WUXGA resolution which is 1920 x 1200 pixels. This is a true widescreen ratio and similar to aspect ratio on most new computer monitors, and best if you want crisp lively images.

One last thing to keep in mind is ease of use. Choose a projector with automatic alignment options if untrained employees will be using it on a regular basis. Also, see what kind of connectivity options the projector has so you know how you will get your presentation on to the screen.

The Best Projector For A Bright Conference Room

Floor-to-ceiling glass windows are the big thing in contemporary architecture. Natural light is a great way to keep employees motivated and productive throughout the day, but it makes projecting an image a difficult task. Bright conference rooms call for bright projectors, and the BenQ MH741 1080p DLP 3D Projector has a bulb as bright as the sun.

BenQ MH741 gives you 4000 ANSI Lumens of brightness, which is over 1500 lumens more than the recommended minimum for presentations in conferences rooms or other areas where there will be ambient light. This means no matter how bright the room is, your presentation will shine in full 1080p true HD with crisp whites and satisfying colors. No need to dim the lights and make your clients or board members feel like they are back in high school math class.

4000 Lumen brightness is accompanied by a contrast ratio of 10000:1 and true widescreen native aspect resolution of 16:9, although there are five aspect ratios available, so you can choose whatever works best for you. While images are quite 4k of some dazzling home theater projectors, the native resolution of 1920 x 1200 is WUXGA 1080p full HD quality. True HD is possible on screens up to 200,” which is large enough for virtually every conference room.

This projector also gives the presenter some breathing room. It comes equipped with 2D Keystone correction, which allows for horizontal and vertical adjustments up to 30 degrees. This makes alignment easier and lets he presenter stand in front of the screen without worrying about blocking the image. Corner Fit also gives flexibility and convenience in the alignment process by allowing the presenter to independently adjust each corner of an image.

The BenQ MH741 comes equipped with a few other features businesses might find useful. It has MHL Connectivity, which allows proposals and ideas to instantly be brought on to the projector from Android smart devices. It also has a 10W built in speaker, “blanking” mode which freezes the projected image while you browse through files, and writing templates for off-the-cuff notes onscreen.

The Best Projector For A Small Office

If your office is lacking the grandeur of a Fortune 500 boardroom, go with the Epson PowerLite 580 XGA 3LCD. It is a very bright ultra-short throw projector, which means it can sit just a few inches away from the screen, which is perfect for smaller office rooms and tight spaces. Presenters will especially like the fact they don’t have to worry about getting in the way of the light stream when standing in front of the screen.

The 580 XGA 3LCD bulb is a very bright 3,200 lumens, which means you can leave the lights on for most presentations. It has an HD XGA 1024 x 768 resolution built around 3 LCD chips, so that will eliminate the “rainbow effect”  some projectors suffer. This is a lower native resolution than Ultra-HD competitors like BenQ, but it is more than enough to maintain color brightness and keep your graphic design team happy.

It has a few other goodies most businesses will enjoy as well. A 16-watt mono speaker means that you won’t need to clutter the room with additional audio equipment. It also has a slew of connectivity options, including HDMI, USB, and wireless connectivity, so impromptu info can easily find its way onscreen.

The Powerlite 580 is a bright, technologically adept, useful projector that can cast a 93″ image from as little as a foot away.

The Best Projector For The Business Traveler

Going on an out of town sales call, but not sure if there will be a projector available? Bring along your own pocket projector to give a presentation on your own terms. Recent advances in LED technology have led to a proliferation of portable projectors at affordable prices. At first they were just a novelty item, but more recent models like the iCODIS CB-300 have enough brightness and battery life to make them worthwhile.

Released earlier this year, this DLP projector packs 1800 lumens and comes with a slew of connectivity features. While 1800 lumens isn’t quite bright enough to cast a clear image in a sunny conference room, it gives a brilliant display in rooms with moderate or low ambient lighting.

The CB-300 is a 720p projector that can play 1080p files and with a native resolution of 16:9 widescreen ratio. It casts an image the size of a large TV, or about 75.” This will cover a white office wall with a large screen with clear and precise images. It is enough for bare-bones excel presentations, and even good enough to show off graphic design work.

Casting your presentation through the CB-300 is easy. It has a Micro HDMI port, 2 USB ports, and a mini USB port. It has a 6000 mAh internal battery that can last for 2 hours, and a 12V plug for an external power source if you require longer performance. It even acts like a tablet, using Android OS 4.4 to run apps.
