Hi,
just a quick question - has anyone tried to measure CRI/RA for multiple lumen outputs?
SC64c even though advertised with the same XP-L2 came out as 88-91 CRI, and not 93-95 - link

Let's keep it simple. My H600w MK2 does use PWM (during thermal throttling at least). Therefore I assumed all ZLs might use some sort of PWM in one way or the other. Therefore "Low...
I don't accuse ZL of using PWM in that sentence, but since H600w MK2 does have high frequency >50kHz PWM, there's a possibility this frequency was lowered to meet the demands of switching step-up transformer, which could leak some of its switching current to the LED in form of IMD as well, if...
@Lexel Wow, thanks for the tip, I was bent on getting the $60 (sic!) H52w, but that JetBeam looks awesome. At $13 it's nearly a nobrainer.
150/30/1lm seems just about right intensities. I don't mind PWM as long as it's above 10kHz and thus not visible for naked eye or camera equipment.
My...
I just want to share my 2c regarding XHP35-powered Zebra MK3s
I don't own any of them, but I'd advice against purchasing one.
First off, it seems that SC600 in its MK3 continuation has shorter shaft which makes it impossible to insert protected cells.
That's at least what people have been...
