In the world of LED bulb, “wattage equivalence” is to give buyers a rough idea how bright the bulb is. i.e. a LED bulb with 100 wattage equivalence is expected to give brightness of a 100W incandescent bulb, regardless the real wattage of the LED bulb.
Both of them claim to be “100W equivalent”. But the lumen is 950 vs 1600. Why they claim to be the same wattage equivalent while the brightness is so different? Thank you!
It has to do with the tint of the led. Cool white or warm white. Cool white leds are more efficient than the warmer leds. The higher cri’s are usually a little less efficient also.
So warmer tints and higher cri will usually require more wattage to produce the same 1600 lumens thats equivalent to a incandesent. Also some leds are just more efficient than others, depends on the make of the led used.
It could be a little bit of markerting trickery. I usually just go for the lumen output I want with the warmer tint and good cri.
Both of them are warm white (same color temperature). I’m not talking about the wattage, I’m talking about the brightness. If one gives 950 lumens and the other gives 1600 lumens, they cannot both claim to be “100W equivalent.
I updated my post above but ya, I agree its a little misleading. Also two different types of incandescent bulbs both rated at 100 watts may not have the same lumens given the difference in how there made. https://www.amazon.com/Satco-S3003-Watts-Globe-Dimmable/dp/B009ADY7G6/ 1050 lumens.
All lamps have a lumens/watt and Halogen incandescent have more lumens/watt than regular incandescent and clear bulbs have more lumens/watt than frosted. In any case, the main problem is dishonest marketing.
