Waiting for better 160 lpw cree/bridgelux/lumileds.

??? I am not sold on any of them. My concerns are: Too expensive per lumen output, too fagile, poor quality control (lacking screws and thermal grease. Underdriving. heat sinking). Or never seeing a real 100 to 150 lpw flood.

(I can use more durability and smaller form factor. I am currently spoiled on 80,000 + lumens on these: http://www.ebay.com/itm/150960088148?var=450145115711 and http://www.ebay.com/itm/150928769289?var=450138309572 (though I think I concluded the Apollo Horticulture was a better brand) on a super light weight aluminum stand http://www.amazon.com/dp/B00XQQJQ5K/?tag=cpf0b6-20)

The one 200 watt led flood is like 17"x13"x5.5" which seems huge for only 13,000 lumens. I am wondering if this would seem way more cumbersome than my current 50 watt led that I throw in a small cloth shopping tote bag with a 15 foot cord, and can stuff under a car seat.

Update:

So far, I couldn't get the dollar numbers to make sense, since I could buy a 500 watt led flood light off ebay for $99, the 200 watt for $39, and the 100 watt warm for $20--with free shipping. So, I bought them all to add to my 50 watt led, and my 1000/600/400 watt metal halides.

My short conclusion: 1. Yes, in relative terms, the led is 2x my halogen for lux per lumen. Same as my metal halide with parabolic winged reflector. Probably, though, store made stamped metal halide street and sign fixtures have a much lower lux advantage than the grow light. 2. I am just guessing here, but in relative terms, the cool 50 watt led is about 3200 lumens (lamp level); the 100 watt warm is 4300 lumens; the cool 100 watt led is 6500 lumens; the 200 watt cool is 13,000 lumens; the 500 watt is about 30,000 lumens. All these led lights use epistar leds, where spec sheet says 80-90 lpw for the cool version at 70 cri. So, my calculation is 8000 lumen max (6000 kelvin) minux driver loss, and glass loss, toping the lamp output at 6500 lumen range per 100 watt.

I do like the warm 100 watt color rendering and size/weight ratio. I am not too keen on the 200 and 500 watt, as the heatsink is a bit too bulky. So the 500 watt is about 3k lux at 5'8", while the metal halide with winged reflector is 4k lux with 100 watt less energy, and roughly same form factor/cri. The 600 watt mh has 8k lux. the 1000 watt mh has an easy 12k lux at 5'8". The 200 watt is nearly too heavy to lantern out a wall.
