I think so. I buy Opus LED bulbs for a few pounds in each. Over five years, i think about a quarter of them have failed. Not a great lifespan! But they're cheap

I think so. I buy Opus LED bulbs for a few pounds in each. Over five years, i think about a quarter of them have failed. Not a great lifespan! But they're cheap enough that it doesn't really matter.
I would be happy to spend much more on high-quality bulbs, but only if they were exactly what i wanted, and i have yet to find anything which ticks all the boxes.
Specifically, i want >= 800 lumens, daylight / cool white, very good colour rendering, in an ES27 screw fitting, and dimmable. There have been a few candidates, but i haven't actually been able to buy them - they're out of stock, or not available in the UK, etc.
- snuxoll 6y ago> very good colour rendering The one area where everything but good old fashioned incandescent lights fail. Makes me wonder if anyone is working on applying quantum dots to LED lamps.
- ksec 6y agoThere are plenty of LED that is CRI 95+. Is that not enough?
- snuxoll 6y agoCRI is a pretty worthless measurement, it only reflects the rendering of color in a specific CCT. It’s fairly easy to make a high CRI warm bulb because it can suck at reproducing the lower end of the spectrum (blue and green), or a cool one where it sucks at the high end, but a neutral temperature isn’t feasible due to the spiky nature of light emitted by white LEDs.
