If they’re consistently out of spec (like say plus or minus ten percent rather than five percent, when +/-five is what you thought you bought), then you may be seeing “”quality fade”:quality fade" at DuckDuckGo in action.
If they’re all over the map, that would sound more like “wounded” (ESD-damaged) components.
I believe that what is happening with the Bedtime bulb is that a large draw on the mains decreases the current to the circuit which is similar to what a dimmer does. The driver sees the decrease in current as a dimmer and decreases output. When the mains stabilizes after the in rush to the motor, the output returns to full. Lamps that don’t exhibit this behavior are likely not “dimmable”.
I don’t know if it’s possible for a dimmable lamp to not react in this way unless it could be programmed to not decrease output unless the current is decreased for >1 second. This would cause a delay when utilizing a dimmer which many users would not like.
We are finding your analysis to be mainly correct. We do believe it is possible to implement a dimmable driver that does not have this behavior, but it will likely require a different topology than what we currently use.
Yep, that someone was me. I discovered this thread by djozz called “SunLike 3500K 95+ CRI midpower led from Seoul Semiconductors tested”, and I said to myself “Hey, Remez builds with the same make and model of LED in 3000k, I should email Adam and see if he can source Remez in 3500k. But nope.
Well the (8) Remez I bought from you are quite impressive now that their tint has been fixed. My rooms take 5 bulbs each, so this is what pricing look like for me:
$35 per room for Remez 7 watt
$105 per room for Sunlike 7 watt
$232 per room for Sunlike 8 watt (with more efficiency)
That’s why I ordered the 3 “spares” to put in my bathroom. I can steal from there if I have some die in the office. Even with bad luck, they are still a better value.
5pcs R.9 would be $46, but you had to cancel that order because of flicker issues on 120v. So R.7 was my only option. And yea, there is a less efficient S.8 option for $111.
