The Brightest LED Bulb: Feit BR40

The Details

The Brightest LED Bulb Overall: Feit BR40

The Feit BR40 produces 2500 lumens of light. This makes it the brightest LED bulb available. It uses only 38 watts of power, and it is rated to last 22.8 years or 25,000 hours.

The Feit BR40 glows with warm white light (3000k) — so it is suitable for indoor use. I installed this bulb in my garage, and it lights up the whole space easily. The bulb is dimmable, but it requires a LED-specific dimmer (here’s an approved list). Feit says the bulb’s CRI index is 80 (which indicates very good light quality — see my note on CRI at the end of the article).

The Feit BR40 is available from Amazon for about $50.

Update: There may be a brighter bulb available — the Kobi K5L1 BR40 LED (rated at 2550 lumens). This is a very similar bulb to the Feit, with a slightly higher wattage (30 watts). It’s a warm color temperature bulb. However, the manufacturer says this light is only equivalent to a 150 watt bulb, so I need to check on this before I give “brightest led bulb” status.

The Brightest Standard Size LED Bulb: Philips “100 Watt Equivalent” Bulb

The Philips 100w Equivalent LED Bulb is the brightest standard-size household bulb available. It uses 18 watts of power to produce 1620 lumens of warm white light. I have many of these in my home, and they produce an excellent quality light (the CRI is 80). These bulbs are also dimmable, and rated to last 22.8 years.

The Philips 100w Equivalent LED Bulb is available from Amazon for around $21.

A 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, its ability to render colors is thought to be very good to excellent. A CRI of 100 is considered natural daylight and is assigned to the sun itself.

The Color Temperature is expressed in degrees 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
Day Light: 6200° K to 6800° K

  1. I am burning out my eyes trying to find the max light for an E12 candelabra base and a 7 watt limit. So far, 650 lumens has been it, and not on any local shelf! Cree said they passed 300 lm/w, but their offering was a 350 Lumen 5 watt 40 watt equivalent!

  2. My mom has macular degeneration and every bulb we have purchased is not bright enough for her. Can we use this light in a lamp in the house for her?

    1. Some of the bulb listed in the article are quite large, but you can certainly put them in a lamp if they fit

  3. No. I have 2 Kobi Electric K5L1 30-watt bulbs which are brighter at 2700K. Standard BR40. 2600 lumens per. But if you want to use 5000K corn cob bulbs you can get them all the way up to 20,000 lumens @180W

  4. Thanks for the simple breakdown. I’m going to try out those Phillips 100 watt equivalent bulbs. I have a room that needs more light
