This is what one fixture looks like over a 40b seaweed.

thanks that looks great
how high above is it?
hard to tell in pict is there a lot of shadowing ?

 

[Hondatek]

It's about 7 inches above the water line. No major shadowing . The little bit on the right side is from the overflow box not the light itself . I would have hung it at 10 inches but it would not have fit inside the canopy. Also the blue are only at 50% and white is at 25% so if you do hang it at 10 inches you'll still have plenty of light .

thanks Honda good to know
I don't have a hood it's a open top

I hear the dollars I'm saving already ...lights been on for over 4 hours and my chiller hasn't even kicked on once.my old metal halide lights would have the chiller running constantly

Oh, I see. Yeah, that would be cool. It seems everyone is buying these Chinese fixtures and re-branding them. It looks like all the same manufacturer.
You can see them right here:

Thanks - if they are all the same "guts" the evolution folks are proud of theirs as they want 399.

The are called optics. They focus the lifht into a beam. Mine are 90degrees but you can get 120 down to 45 i believe...

 

[Reefer4eva]

Any chance to they shield the light? My living room is blinding.if so where can I buy them?

No. It just focuses the light more downward to get a deeper penetration but that sacrifices light spread. It's great for deep or small tanks tanks. it works like a flashlight with the beam focused to a smaller area.

 

[Reefer4eva]

Sorry I'm new to this led thing,I did a lot of research as far as optics go.so I think with my setup (which is a 34 solana) going with a 90 degree would be perfect.i have my lights hung 10 inches above the water line on a 20x20x20 tank,anyone know where I can buy them?i seen some that have the double face tape adhesive on the optic holders this would be perfect

 

[Reefer4eva]

Are the optics measurements 14 mm x20mm?can someone answer this for me so I can order them

How many led pendants will i need to stretch over 100 gallon tank, 6 ft by 18" by 18"

Depends on which fixture your talking about,in my opinion I would go with 3 but that also depends on what kind of coral you are housing

 

[Dimdim]

Lets say i wanted the bridelux dimmables 120w.

 

[Reefer4eva]

I have one on my 34 which measures 20x20x20 and its more than enough you might be able to get away with two with a little shadowing on the sides

 

[Dimdim]

Its not a very deep tank, i might get two, then get an al sol or radion. To supplement the middle of the tank. Its 18 inches deep and tall.

 

[Reefer4eva]

I love them and so does my corals, i just need optic lenses for mine (they light up my whole room

 

[Dimdim]

Ive heard of issues with that problem exactly! If i do go that route im gonna build a canopy about 14 inches tall to house the leds

 

[Magma]

Alright guys im ready to purchase some in the next few days, just wondering from anyone who has bought VIA ebay. If you purchase them with optics, are they easily removed if I choose not to use them? OR What should I be looking for.

I know i need 3 fixtures as my tank is 72x20x20 and im going to be going for the Whites/Blues only. I was thinking I may end up emailing the guy at reef breeders for a cost to ship to Canada but I might end up going the ebay route. Either way just like to know what style of optics I should be looking for.

 

[Dimdim]

Your going with 3 over a 6 foot tank? Sounds like ill be able to do the same. I know some ebay sellers ship from the usa to canada. And i wouldnt have a clue about the optics. I think they come installed and thats that. If your going with 3 on that tank, 90 degree or 120 or 130 would be good optica 90 probably the best bet
