Anyone Using LED Spotlights to supplement Metal Halides?

[arc eye]

I am setting up an open top aquarium and I planning on running one large lumenarc on a 400w ballast as my main source of PAR.

I am looking for a tasteful way to achieve actinic supplementation and the ability to create a dusk/dawn effect.

I came across a few people mentioning the use of either LED or 20K metal halide spot lights. Below is a link that shows basically what I'm talking about.

Has anyone tried LED spot lights? Or better yet know where I can get them to try it myself?

I was also planning on using LED spotlights on my new tank, but i have no experience with them

Also interested. Will be following the thread. Users please help!!!

I know someone out there is doing it!

I have a 400w hqi and also 2 x e27 blue LED bulbs with 70 LEDS each. The HQI overpowers the LEDs to such a degree that I feel that having the LEDs on with the HQI is just a waste of electricity...! I can make them out in the shaded spots, but I can't tell if they are on anywhere else.

They are good for dawn/dusk effect though. They will give you shimmer-lines wich t5 will not.

i have heard that you can do it, but you would need a ton of led's and wouldn't be cost effective b/c of it. similair to what herzberg said

If you aren't using high powered LEDs like Cree XR-E's with optics, then don't even bother.

How about 20K metal halide spotlights?

 

[HookedOnReefing]

"E27" is the type of base/fitting. E27 is a bulb with a large base/fitting (like your standard 100W household light bulb) and E14 with a small base/fitting (like your "candle light" bulbs).

Hope my explanation makes sense.

Glassboxdesign and Invincible569 use them.

google their names you will find their blogs both of them have excellent blogs.

still looking for some ideas..........the profilux sticks and spot lights look pretty nice, but you need the whole unit to run them.

liveforphysics is using them on his 48" x 48" x 24" tank....unfortunately the site that was hosting his pics went down

You can DIY (if you're handy with a soldering Iron and can read a schematic) some spots using the Cree LED's and lenses. Just 1 LED and lens per "spot" will do the trick...and you can run them all from one CCSD.

I'm using the simu spots on my profilux and love them!

The profilux simu spot works great for dawn/dusk/moonlight, but the main lighting will overpower it to the point that you can't tell the difference between having it on and not.

I just put one of these between my two Sfiligoi twin 400 watt MH reflectors.

It definitely stands up to 1600 watts of MH with SOLID actinic supplementation for the middle three feet of the tank. Even at the bottom.

I have JUST the UFO growlight on right now, and, it practically lights up the whole tank. It looks like a haunted house in there!
