Uxcell a14031300ux1363 2 Terminals SMD LED Light Emitter Bulb, 1W, 3V, 10 Piece, White AMAZON. These puppies are super bright like 10 times the original. I figure to keep the single good one and use it as a Moon Beam night light.
I'm too tired to go look right now but I think it was 5 out of six were bad in the gifted lamp I am working on. Gifted by a friend that did not want to waste his time. Took about 4 weeks from HongKong direct for them to arrive. Yup Pictures later when it rains or freezes.
they aint got a visible heatsink either high power LEDs usually require a gud heatsink plus regulated power at the exact proper voltage that is needed to drive that particular LED not all LEDs are the same
Keep trying , I've gotten good ones out there in 12 volt DC that work well ,I have them all over my house,. I repurpose old burnt incandeasant with DC 12 volt LED and wire in the lamps to my 12 volt wiring through out the house. Before the LED was available i was using Quartz and other automotive lights .
