Customized T5 Fixture + Leds

Recommended Posts

I have a Aguatinics Constellation 7 bulb 48" T5 fixture that has two ballast that can be set to run 2x54, 3x54, or 4x54 T5's. One leg of a ballast went out so I swapped the two ballast around in the fixture so that the center bulb of the 7 was disconnected from the ballast. I've been wanting to run a T5/LED combo for a while now, so I took advantage of the bad ballast.

Here is the fixture after I unhooked the bad leg of the ballast.

I then purchased a 2"x1" U channel of aluminum. I drilled and tapped the aluminum to hold 25 Cree XT-E Royal Blues.

I drilled some larger holes in the end of the U channel so I could mount it to the fixture.

I removed the unused T5 end caps so I could use the existing holes on the fixture incase I ever wanted to go back to all T5's

My next step was adding the LEDs to the u channel. Unfortunately I did not have 25 working LEDs, so I'll be adding some more in the near future.

Then I started re-assembling the fixture.

Test after re-assembling.

And a picture of it over the tank with only the LED's on.

Sorry, these pictures were taken with my phone so the blue looks horrible.

If using a smart phone download an app called Snapseed, under "Tune Image" go to Warmth and slide it to 100% that will take care of the blue wash out from the LEDs. Great DIY btw!
