There are very few options for CRI95+ SMD MP LEDs with reasonably priced worldwide shipping.
Actually I have found literally just one offering on Aliexpres, for 2835 LEDs. Everything else seems to have expensive shipping.
I suspect Iām missing something and I spend merely an hour or so on the search. But anyway - this is not something widely and easily available for a reasonable price.
Are midpower leds often used on BLF? Before investing in them I would want to do an inquiry!
Iām planning on a midpower led solution for the BLF lantern, and a few people use them in flashlights with VirEnce boards, but that is probably not a high volume.
Do those Ikea tealights have their own flicker circuits, or is it integrated in the stock LED, in which case you lose the flicker effect when swapping the emitter?
The LED tea lights I have are the latter type, so Iām keeping an eye out for something else.
I finally got the 2300K LEDs and tried them in my rechargeable tealight candles. I absolutely love it, itās the closest Iāve been to a real candle light, and in a light holder of any kind it looks convincing.

Here they are with their included diffusers, looks pretty good. Canāt wait to solder all 12 of them and place them around the house.
I still use real candles on my living room table due to the cozyness and smell, but these are a lot safer to use unattended around the house, especially with cats around.
I hope you meant to say ā10 in parallel to an AMC7135ā. But why do you choose AMC7135 and PWM? :facepalm: The Arduino could be used to sense current over 3x sense resistor paths, precisely tuning a driving MOSFET VGS in each of them for accurate, PWM free linear current control.
No, thatās fine.
For 10 in series you need 32 29 Volts.
For 10 in parallel you only need 3.2 2.9 Volts, like from a single Li-Ion cell.
The AMC7135 will eat up a minimum of 150 mV.
