I had a similar idea and a pair of 5000K CXA3590s hanging around. Running them at 250mA and no temp droop to speak of, they are about 65% efficient or 210lm/W. The 5000K Vero 29 at 250mA should be about 58% efficient or 188lm/W. Awesome vegging lights! Cost is $5-$5.50 /PAR W, much less than I recently paid for my Oslon SSL deep reds LOL.
Mounted on Alpine 11s so they can be cranked up if necessary.

Your all taking the light vs. heat efficiency wayyyyyyyyy to far lol, to a point of noooooooo return. The middle ground is very much a'lush.Crude math, just stinking.
1x vero 29, 70cri, 5000k+molex EZ-mate: $35
1x 2"x5.886" Heatsink: $3.50
1x Fasttech driver Link: $2.50
=$41+($41*0.15)= $48
Estimating about 61% efficient even after temp droop, 10.5w power draw.
A bit expensive but it would beat the pants off a CFL and would be fairly easy to assemble.
