New Batch 10 watt LED's Arrive Back Spasms
Yep, they arrived. Made an adapter connector to connect a pair of plates to a 12.24 volt regulated power supply. Eight of the twelve have one LED segment that does not light Two of the twelve ha...

To be of any use, one board should emit ~350 lumen. This is the brightness equivalent to 20W incandescent (leaving color temperature aside, which seems to be a problem with Chinese).
Cheap LEDs are - normally - 3 or 4 times more efficient than incandescent, so such a board should draw 5-7W.
Mex, sounds like you've got 10W equivalent, and in 5000K color temp at that.
China. No comments.
There is still a huge lag in the industry, probably caused by the makers waiting for a big enough profit margin.
You can buy 200LM per watt LEDs from Cree and Philips, but finding those LEDs installed in something useful at a reasonable price is impossible. I decided to go the build my own route instead, but that's not exactly bulletproof and easy.
I chose LEDs from Philips rated at ~180LM per watt. Running three LEDs at two watts each, I haven't figured out a way to get rid of all that heat inside a small fixture designed for incandescent bulbs. The dumb incandescent bulbs are not affected by heat, so the fixture can be small and poorly ventilated.
