Anyone got any ideas about these L.E.D. lamps?

[cbianco]

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...

That's good to know.

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

Let's figure the low side of the initial ownership costs:

Fixture 4x24"=$180
Lamps 4x24"=4x~$100=$400
Total of ~$580

Considering the cost of a high quality T5 fixture, the cost doesn't seem so bad. Oh and those PAR numbers are amazing, makes me all tingly, lol.

When you purchasing one Alex?

It says it will fit in a regular t10 fixture but runs on household current. You would need to wire around the t10 ballast.

I've been lurking on this thread and I've been searching for more info on how many bulbs you would need to replace a MH. This video looks like they used 8 to achieve the same par as a hamilton 250w........

yeah that is correct. the fixture that has the controller is an 8 bulb unit. the total cost for a 36" 8 bulb unit is ~$1000. so initial cost is high. but for 250w mh power and no bulb changes for over 5 years, the cost seems ok. i think if you were to buy a used 250 setup [ballast, fixture and bulb] you would look to spend ~$350, then add in the cost of 2 bulbs a year for five years. another ~$750 [250w XM @ $75.00]. your already over the $1000 mark. and i haven't even factored in cost of electricity used. not to mention the need for a chiller, another ~350-500 if used...

i have ordered 3 12" bulbs that i am going to retro into my biocube. to try it out first. i am definitely into these bulbs, but there might be something awry, you never know right. i am just waiting for the guys to get back from china with the shipment. i have been told that they should be in in 2 weeks. if all goes well, i will be ordering a full 36" unit with 8 bulbs within a couple months. the website i posted earlier shows growth pics of their 55g sps tank, and the results look very promising.

Alex is gonna pioneer the way. As long as they dont end up like PFO we are good.....

[aggman]

haha. for real.

i so want a PFO solaris too..just the things it can do

[subsailor]

good luck as they are not around anymore. They got the snot sued out of them for patent infrig and closed up shop. Not a good light to have as if the littlest thing could go wrong and you would be stuck with an overpriced tank top.

no bulb changes for over 5 years, the cost seems ok.

From their website (www.sunbritelighting.com):

Any light bulb is a wear and tear items, expect a 10% to 17% drop on the PAR reading for the first year, 5% to 10% on the second year. We suggest replacing the bulbs every 3 to 5 years. (SPS-UV bulb) once a year....

I almost bought LED lighting a year and a half ago. Sure glad I didn't. The patent suits will probably put these guys out of business too. Then there are all of the warranty claims folks have had. if you have to send your light in to be fixed/repaired, you have no lights...

I'm kind of into LEDs, as I've replaced most of the lighting on our boat with state-of-the-art (unlike these) LEDs. I like them, but not for growing corals. Soon, probably, but not quite yet...
