Oh boy! Someone didn't see the last sentence. 😐

Wow very bright

Bright and purple cousin!

Interesting, it looks like the phosphor on some of the LEDs has burned and faded away! This is quite common on early LED bulbs. I believe it has to do with the heat the bulb itself gives off causing the phosphor to disintegrate. With the LEDs underneath the phosphor being blue/purple I wonder, does anything glow under them like a blacklight? Very unique pattern it gives off for sure!

You may be right. What’s weird is that all the LED diodes are still working, none are burned. It may be a similar LED light bulb like the Philips ones with the weird yellow envelope covering. I couldn’t really see ifanything fluoresces on the purple side as the white side is quite visible. I’ll keep running the bulb 24/7 to see if the other side turns purple. 😁 The purple light looks coos I may add.

Mercovay is most likely right. The phospher has degraded, showing the true color of the light. It might be of some concern because some white LEDs are ultraviolet underneath the phospher. But from what I've heard, it's more often a blue LED.
It's a pretty neat effect effect though.

Heyas! Indeed, that’s a good explanation. Also, I suppose these bulbs weren’t designed to be run so long. They recommend 3 hours per day. Let’s see if the other side turns purple too with time to make it a cool party light bulb. 😀 Yeah, if this was UV light it wouldn’t be good. But I honestly don’t think that would be the case. Well, I hope so.

I've never seen a "recommended" amount of time for an LED light bulb listed on the product label. Usually the label gives an "up to" lifespan in years "based upon" a certain number of hours (less than a typical night) each day. I would suspect that had this particular bulb only been turned on during the night it would have lasted much longer. One thing I now understand from yer responses above, is why the earlier models of LED lightbulbs had metal or plastic heat sink fins between the bulb/cover and the threaded base. Newer LED bulbs don't always have those fins for some reason.

Hey Scruff. sorry for the late reply. The lighting facts on light bulb packaging do have a recommended use for light bulbs. That's why the manufacturers can get away with the claim that the LED light bulbs will last 23 years. The disclaimer says to use it 3 hours or so a day. 😀
