100 Watt Hybrid Led DIY

[DBLeite]

I am building a 100 Watt Led for my 125 gallon mixed reef.

I received my 100 Watt Hybrid Epistar chip in the mail yesterday and wanted to share some pics with everyone.

I originally made 3 lights with these chips last fall and I love them..... more importantly my tank does too..
I had to replace 1 of them and wanted to go in a different direction this time.

The heatsink is 5"x 5" and was salvaged from a small wine fridge.
The chip was attatched to the heatsink with 2 part Arctic Alumina thermal adhesive.

When I bought the chips they came with a non-dimmable, non-waterproof driver, a bit too ghetto for my liking.
I went with a meanwell HLG-100H-36B this time, much happier with the meanwell.
I also added a potentiometer to allow for dimming.

Looks good

Thanks

After letting the adhesive set up for a while, time for the soldering.

The optics for these chips are 90 degree lenses that I attatched with high heat silicone.
When I bought the original sets last year, the adjustable lenses were not available. They are a really nice upgrade from the ones I have.
I added a stainless steel 8/32" machine crew and wing nut to attatch a hanging wire.

So after connecting the hanging wire and a couple wire nuts, voila.
Let there be light....

My other 2 lights I fashioned out of PVC fittings to mimic a " kessil " look..
The problem with that design is the heat dissipation.
That's the reason that I wanted to go in a different direction with this build.
I wanted to get it up and going, but not sure how I want to hang it.

Can we get a FTS to see light spread with just those lights on?

 

[DBLeite]

Will do tomorrow.

very nice! I love the heatsink I took apart a mini fridge for one of my led also

Looking good!

Thanks guys.
Yeah, can't beat a freebie heatsink.
I'm trying to get away from hanging the light with wire, not sure what to do yet.

After much thinking, planning, and brain picking, I thought of utilizing the swing arm lamps that I have my par 38 boost Led bulbs in.
I'm not that crazy about the appearance of the lamps, but the maneuverability works out good for me.

Initially I tried to mount/hang my current set-ups to a lamp for a weight test.
As they were, they were far too heavy for the lamps springs and design to handle.

 

[DBLeite]

I scored a few of these heatsinks for a silly price.
The weight was much lighter than my current heatsinks, just wasnt sure how to connect them to the lamps.
After thinking about it until smoke came out of my ears, Andy from Underwater World thought of an angled or L bracket.
I used some extruded aluminum that I already had.
I cut the aluminum with a 4" grinder.
