This is just a FYI news update.
Saw these on E-Bay. It is the highest LM/W ratio I have seen available thus far and easily puts it in the HPS league.
The problem? Very expensive. $40 for a 10W/1300LM light. For less than $20 you can get a less efficient, but higher output 20W/1800 lumen light (90LM/W).
Over time these and similar units prices will continue to fall.
