*So after further tests and checking on the one LED that flickered & went out, its definitely a dead emitter… Its my luck to get a bad LH351 4000K for the lantern testing.
I have flowed on the three good ones, but can’t do a test of the four compared to two LEDs until i can fins another one*
EDIT I discovered when i gently push in on the LED dome with a pair of tweezers, the LED comes on. So it appears the internal bond wire came loose. I have a short video fo the LED flickering, but don;t know how to post videos here without using Youtube.
As of right now I am in need of a replacement LH351D 4000K High-CRI emitter to test the lantern using four to compare that configuration over the two-LED set up. DO any one have any sources where i could get one?
Looks like you’re good for now, but Digi-Key actually has 8 varieties in-stock with no minimum. Different CRI’s (70-80) and CCT’s (3000-5700) available. Link
