Well, finals are over and I finally have some free time!
I got a private message from a member here asking how I installed my lunar lights.
I thought I'd just post it here in case anyone else was wondering, saving you the time of asking.
I'm using a Current Dual Soft White LED Lunar Light attached to my "FishNeedIt" metal halide fixture.
I like this LED fixture over others because it does an excellent job mimicking moonlight. Blue seems unnatural, IMO.
I avoided LED strips because for an aquarium of my size, that would be too bright. I wanted to leave shady areas should my fish or shrimp ever wanted a place to hide.
Initially, I planned to attach the fixture directly to the MH pendant.
But, to keep the LEDs centered, the only place was on the MH's glass cover.
I knew I didn't want the LEDs there, because the MH's intense heat would burn out the LEDs in a day.
Instead, I attached the LED fixture to the pendant with an extra conduit clamp I had laying around.
The conduit clamp turned out to be very effective keeping the LED fixture away from the very hot surfaces of the MH pendant.
Yes, heat still reaches the LED fixture via conduction through the nuts, bolts, and conduit clamp. But, the heat that does reach it is negligible.
As you can see, I'm using the thin conduit clamps.
These are easy to bend if the LEDs are pointing too far in front or behind the tank.
For me, it was pointing too far back, so I bent it so the LEDs shined in the middle of my tank.
In order to attach the LED fixture to the conduit clamp, I simply used a bolt & nut to secure it. Easy!
Here's an angle from below. Sorry about the glare.
In order to attach the conduit clamp to the "FishNeedIt" MH Pendant, I had to drill a hole in the fixture.
I used a simple Dremel and drill bit to drill the hole. Once drilled, I attached the conduit clamp to the pendant just like I did with the LED.
Nut & bolt. Easy! Of course, you'll need to unscrew the sides of the "FishNeedIt" pendant and remove the protective glass to reach inside.
Well, shoot... I put everything back together and hung the pendant back in place.
The extra weight of the LED fixture made my MH tilt in the back. My MH spilled its light all over the floor in front of my tank.
Luckily, the solution for this is also cheap and easy!
I opened the MH pendant back up and threw in a whole bunch of extra nuts on the opposite side of the LED fixture.
Eventually the weight evened out and the light from the metal halide was back directly over my tank.
Never had any problems from the nuts, they seem to be handling the heat inside the MH very well.
Hope this helps anybody with a "FishNeedIt" MH Pendant interested in adding lunar lights.
