oops i knew i forgot to post something.

here is a pic i got from the only retailer i could find.



not bad for a 5 year investment. price is per bulb. you can do retro or buy the fixture which cost like $300 for a 48".

im trying to find some info about those. A guy on nano reef which does a crapton with leds said those wernt the greatest light cant remember why though....still looking. personally I would do a DIY system about 2 months ago i purchased 18 cree xre leds...enough for prolly at least a 20g cost about 100 bucks. all i need now is a heatsink and a couple of drivers (about another 100) and should get comperable light to a 150w metal halide and is fully adjustable can go from 6.5k to 20k with the turn of a knob.

EDIT found this and this

Please post that data when you get. That will be great news!

yeah i read evil66's threads. he does know alot about the cree's.

but i wouldn't go by any 'hobbyists' info on these. these just came out in april and the owner of exotic aquatics in sacramento, ca. is still in china getting his order into the states. i spoke to the owners personally and have already pre-ordered my set. no hobbyists have had an opportunity to test these out. sanjay and grim haven't even posted any tests on them.

and i think the video shows that they have more than enough power to grow anything in your tank. the par at 24" was over 340. a 150w mh at that distance had only 150 par.

also i am not against evill66. i have actually pm'd him several times for help on a led diy for my biocube. he helped me out a bunch and the led's solved my growth and heat issues.

Hey Alex,

Nice find.

Do you know if the T5/LED lamps are running off of standard balasts?
Are they plug and play into existing T5 fixtures?

They look promising and the PAR numbers are great. Definately costly though.

no they aren't t5's. they are t10's i think. and they have internal drivers that allow them to be placed in regular fixtures.

oh and did i mention that the inexpensive fixture you can get allows the bulbs to be individually controllable!!!

i really don't know how these bulbs aren't all over rc yet...
