The easiest way I’ve found to check for PWM is to wave a thin white card rapidly through the beam, against a dark background. With this method, I’ve been able to see PWM up to about 20 kHz.

Here are a couple pics showing how it looks… first at ~500 Hz and then at 4.5 kHz:

Or, with a sensor (or an LED) connected to a nice DMM, the frequency can be measured directly. With this method, I can get precise speed measurements for everything I’ve ever tried (the fastest I tried was 31 kHz, and it worked well).

Thanks jon_slider
Those ball cap pics were just what I wanted to see. It looks like it’ll work great!

I would take one in copper :-), hold the magnet, change to keyring style that does not prevent tailstanding

Great images, fortunately we wont be needing to worry about PWM with the ReyLight Tool… Im really impressed with the package hes put together.

Looking forward

Which Nichia, what CRI?

afaik The N219c is only 80CRI.
Hoping we got an N219 a or b, with 90CRI, yes?:slight_smile:
Looking forward!

Greetings I am new here. A Google search has lead me here on a quest to obtain a copper version of my favorite flashlight.
Can I get in on this group buy?

253

@ToyKeeper,

That works extremely well! I’ll have to give that a try, no more losing grip on my light and flinging it across the room.

254

Hi, it's 219B, 90CRI.

255

Just informed, Nichia has arrived HongKong, and will be transported to Lumin on Monday.

The new firmware is ready, and we need to confirm the order qty, then flash the drivers,assemble and shipping.

Paypal will be posted in OP, counting will end within Nov. Will order a few more extras.

256

Can I get 2?

Yes, sure, pls read the 1# post updated.

I ordered one, thanks Rey, perfect little light !

btw, do you have a more exact description of the Nichia 219B led? (is it a V1 R9050?)
