I put a Samsung L351D HICRI led in my D4 Emisar and M43 Meteor lights

I’m curious about the beam, I don’t think I’ve ever read any review/tests with samsung emitters

Samsung LH351D color testing

Kiriba-ru sent me a Samsung LH351D for testing. The emitter tested is a model number SPHWHTL3DA0CF2R1W2 with 5000K, CRI70 and rated luminous flux of 460lm at 1050mA. It fits on a XP/219/319 MCPCB. Now I’d like to test the higher CRI options, which are also plentiful. I tested it with the small OP reflector from the Reylight Pineapple. It was sitting on an MCPCB, so no heatsinking and no stress testing at high amps. I’ll put it later in some light Visually I’d rate it close to the Nichia 219C …

Samsung LH351D 5000k LED output test by Texas_Ace - Amazing output, low thermal resistance but high Vf

kiriba-ru sent me these LED’s to test. I had never even heard of them before so I didn’t hold out a lot of hope for them but they really surprised me! They have one of the lowest apparent thermal resistance I have seen so far. This can be seen in how the output hardly jumps from a cold start, that says it is moving the heat away very efficiently. The output is also very impressive at over 2200 lumens! This is more then any other 3V LED I have hot tested. The XP-L2 will make a bit more from a co…
