Update my amount of led from 3 to 10 please

81

Done.

I am in for 20
I salute your engagement :+1:

83

I’m in for 4, so long as an actual test shows no donut hole.

84

I already said it on Reddit - but please put me in for 20, blueswordm.

thank you!

and the closer to 4000k the better for me (4000k is my perfect cct). 4500k is exciting too, though.

85

Done.

86

I prefer 4000k for general purpose flashlight. 2700k or lower for bedtime use.

Put me down for 20!

Put .e in for 10 in the US.

I’m in for 20.

If the sample shows positive results, I’ll increase to 40.

93

I’ll take 50 if fogofwar is able to confirm low CRI samples look good in common optics and OP reflectors.

94

You’ve all been added :smiley:

95

@BlueSwordM, update me from 5 to 10 please. Doing what I can to make it happen.

Plus FOMO because I ordered 1/2 of what I ended up needing of the initial release of the DA0GF4RTS6’s and AZHU’s 219B D220 SW45K’s.

96

Done.

97

Would like to see beamshots of this first but I am interested.

Interesting update

Interesting new information for you my friends.

I’ve actually found another manufacturer making a high CRI 5050 3V LED!!!

Even better from Rayten in some ways: single emitter die(so it should have higher intensity and no cross-die), Ra9580 (not a “puny” R9070) and a nicely lower VF for better regulation :smiley:

The only downside? Much higher thermal resistance(5C/W instead of 2C/W) and a bit lower efficiency.
