It was a really nice deal and I wished i was smarter and had bought more ..but these emitters are already really cheap anyway.
Great shots bob mcbob ..
*note to self :hold off on killing bob mcbob
The LH351C MF ones that were super cheap are a bit worse in tint than the more expensive but lower flux bin KF ones.
Measurement from the hotspot at 1 amp with a Yajiamei 10° beaded optic.
Rated (700 mA)
1000 mA
2000 mA
3000 mA
4000 mA
5000 mA
Output seems to taper off after 4 A.
Pretty much zero tint shift within the usable beam using the Yajiamei.
However, very visible green tint in the corona with the X7 SMO reflector
You say output seems to taper off after ≈5A, this means their die size is small, doesn't it?
Ouch with the tint! Slightlly less than promised CRI.
I have 3x LH351C MF pieces on the way, if they dedome right they may be a great emitter for throwers.
Cheers ^:)
The die is quite small yes, not quite as small as the 351B. The KF ones were better in tint but the one I tested has much lower output and tops off at about 3 amps. So filtering the green out on the MF is better. I did the output test with one sample each so YMMV.
