I bought all new Philip hue bulbs going on 7 or 8 years ago now and not a single one has gone bad. Maybe you're just buying cheap poor quality bulbs? A 100 out of 100 success rate after 8 years.

No, I started with Philips Hues but then gave up and migrated to Cree light bulbs with Lutron Casetas because the Hues kept dying. These are over 2 different houses as well. I wonder what is going on if it's just me

Had a ton of issues with the original Cree bulbs. They underglued the glass bulb and it came off with thermal cycling. They also put the LEDs on a metal core PCB they bent into ~10-gon tower. On the bends, the traces apparently would crack which led to overheating and a burn spot.

Cree is now no more; the bulbs are just a brand for FEIT who imports the same unreliable Chinese white-label bulbs.

Which brand do you suggest?

Every Philips L-Prize bulb I bought in 2012 is still working. Some have been on about 30% of the time since purchase. A few have been dropped multiple meters onto concrete; oops. Well made LED bulbs last. Cost-optimized ones may not.

I had a bunch of Philips Hue LED light bulbs until they started dying within a couple of years or less and the replacement costs were ridiculous. That's when I switched to Lutron Casetas.

I run about 50 Philips Hue lights and I’ve replaced 3 in six years, so definitely not as reliable as the L-Prize lights, but not awful. The L-Prize bulbs are built like tanks… when you drop one you check the floor for damage before the bulb.

5700 is a terrible temperature for lighting unless that matches the daylight. Soft white and even reddish is much better at night. Presumably, most artificial light it used at night. 2700 is more like it. My LED lightbulbs change temperature based on the time of day and are dull red at night so you both don't wake up and you don't stub your toe. Show me a non-LED that can do that.

Lighting color is cultural. Go to Asia and you'll find many places, commercial and residential, lit with 5500K, traditionally fluorescents.

I've heard a theory that it has to do with genetics and lower eye sensitivity.

I've never had LED lights last anywhere near the purported 5-7 year timeframe. The worst ones are the small decorative ones with the tinier screw part that my house seems to have an inordinate number of. Those last maybe 6 months and then they start getting dimmer and then all the lights in the circuit get worse at once. I like LED lights immensely but the idea they last even 2 years is a lie in my opinion.

I bought a whole bunch of GE LED bulbs figuring big name, probably more reliable. Nope. Diabolically bad. Never again.

Misled

I've been seeing the misspelling of the past tense of lead (led) incredibly often in the past couple years. It's clearly confusing that lead is an actual word, so it may seem right and likely doesn't get caught by auto-correct, although I assume grammar correction should catch it.

> Show me a non-LED that can do that. Many of use simply don't find LED lights, no matter the color they try to simulate, enjoyable. I find my LED lights, including fancy decorative ones, bearable only because I always use one real, old-school, warm white (more like yellow really), incandescent (hence non-LED) light in my living room. And, yup, if you know what you're looking for, it's totally possible to still buy i…

There's two separate issues where LEDs still have a hard time competing with incandescent bulbs: CRI (really R9 or other deep-red measures, because CRI stats are sort of gamed) and flicker. Most LED bulbs also have poor heatsinks and are more likely to die if kept inverted or in enclosed fixtures.

All of these are individually solved problems, you just can't buy a bulb that's an e26 retrofit that satisfies all of them for whatever reason. If LED bulbs actually lasted 10 years, then there'd be 10 year warranties. Yet even the most expensive boutique LEDs (e.g. from YujiLED) are only 3 years at best.

The old Cree bulbs that Home Depot used to carry have been great for me. I need to find a new supplier though because the brands they have now are junk that last a year or two if I'm lucky.

That is weird. Mine are basically infinite.
