Not 1500 lumens
June 29, 2019
This is for the 100W equivalent warm white bulbs rated at 1500 lumens. Upon installing the first one, it was obvious to me that it wasn't as bright as an incandescent 100W bulb. I took the light meter app on my phone and measured a 100W incandescent bulb and got a reading of 1430 lumens and a color temperature of 2900 Kelvin. Substituting these LED bulbs, I got a lumen reading of just 950 and a color temperature of 2800. That's over 1/3 less than the rated output and so I tried several out of the box of 16 and got very similar readings.
I then went to the local big box store and bought a name brand 100W equivalent LED bulb. Physically, the bulb is quite a bit bigger and the light output was a whopping 1470 lumens at 2900K color temperature. This was what I expected from the Amazon branded bulbs so was disappointed. I did check the markings on the bulbs to make sure I didn't get the 75W equivalent and no, these were supposed to be 100W equivalent.
This is the first Amazon branded product that I have been disappointed in - clearly they did not quality test these bulbs before branding them and selling them.
