fwiw, LEDs with higher CRI will generally be less power efficient, so the premium category has a 3-way tradeoff between brightness, power, and color quality. It's common for high efficiency LED lightbulbs to be much worse at illuminating red objects.
- SPICLK2 8mo agoTrue enough, although CREE's XT-E offers 140 lm/w at a CRI of 80 and a colour temp of 3000k. I assume this product has not met any regulatory requirements, because selling a ~600W hot plate suspended at eye level cannot be legal. These LEDs are just the ones found on imported LED strips. Adjustable colour temperature is a novelty that is not compatible with LED efficiency or lifetime.
- camtarn 8mo agoCRI of 80 is not great. From my reading, you want CRI 90 if you want light that's pleasant to exist in.
- SPICLK2 8mo agoFair point. Given that this product has adjustable colour temperature, I really doubt all of the lumen, CRI and watt values. It sounds like the designer also got stung when the chosen LEDs didn't give the expected power output.
