great little shop you guys have there, great looking corals and tank.

i would say the spread of the spotlights are roughly 1ft x 1ft range for the 27W version and abotu 10"x 10" for the 15W version. Penetration on the LED are fairly good, with the light at 10" above the surface and the PAR meter 10" below surface we were getting ~250PAR for the 27W and ~160PAR for the 15W. Considering MH coverage is roughly 24-30" depending on the reflector, these little bulbs are pretty up to par(no pun intended) in terms of area of coverage and PAR value(almost equal to a 250W if not equal).

And it does just fit right into an average lighting socket so if your socket breaks somehow something at homedepot or hardware store can fix it.

Thanks! Glad you liked it, come drop by again once we get more things up and running!

Looking Good Eugene! Great to see a more affordable option in LED spots.

Here's a review of the PAR38 lamp and its PAR coverage at varying distances THROUGH THE AIR:

FWIW, the coverage is pretty pathetic but would suffice for spotlighting - certainly not a MH replacement.

i don't think it's fair to say coverage is pathetic or to compare them directly to MH as they aren't intended to replace MH over larger tanks. LED's can produce performance equal to MH over a small area which is why you need a large array of LEDs to cover a larger tank (I'm using 80 LEDs to cover my 48"x18" 75 gallon). But for nano tanks or spotlighting these Par38 type bulbs are a great option.

That LED spotlight looks really cool. Any word on getting any that have more blue colour? It's kinda white for my liking.

If you look into the PAR38 lamps by evil66 those are 15W Bulbs, they are not comparable to MH much in terms of PAR value as well as coverage. Since they do roughly 10" x 10" and right after that the PAR value pretty much becomes non existent for a large tank 1 bulb will not cut it to replace MH, and its not made for that as Ron has pointed out. Also the test in the glassbox design was done with 40degree optics which isnt really all that useful for reefing applications. The O.C ICE CooL.E.D comes standard with 60degree optics and they have a much better coverage area compared to the standard evil66 PAR38s. If you look at the nano tank above, lite by the 27W version the footprint of the tank is 14"L x 8.5"W x 10"H and we have about 1" on both sides thats a little bit shaded, so these are definitely able to power bigger tanks just not so much tall tanks.

Now looking over across the ocean to Japan/Taiwan/Hong Kong, Spotlights has been used with great success, they use less power, injecting less heat into the system and most tanks you see thats 50-60gallons or above has at least 5+ on them. If we were to guess at the wattage total i would say 5 spotlights would only use no more then 250W(and this is over rating them) over a 3ft tank, are the tanks in Japan able to keep SPS or any coral they want? I think we all know that answer, but these bulbs were not made to replace MH by each bulb and if you do plan to use spotlights as the main lighting system multiple would be needed, either that or as Ron has already mentioned earlier in order to light up a system thats big, you would build a big enough array that would allow it to illuminate the footprint of the tank like a MH system would.

I am personally debating whether to switch over my 2x150W MH + 4x T5HO lighting setup over to these spotlights, as im running 2 over my frag tank at home and couldnt be happier with the way that its bringing the colors out of the corals.

The Spotlights come in 2 colors right now, a 12K which is what the latest photos were taken with. and a 14K which unfortunately we dont have a bulb right now to show. I would say the 14K bulb is an ice white color, meaning that its white with a tint of light blue to it.

we are going to get a sample of a 20K bulb to see how blue it will get, but we are afraid that since there will be too many blue LED and not enough white ones that the brightness (lumens) to the human eye will seen dim. So we have to test it out first to see if we will bring one but definitely we are looking into a 20K version
