Metal Halide

Marine Color Brand 400w 20,000k Hqi Single Ended E40 Socket Metal Halide Bulbs for Aquarium Marine Tank Coral Fish https://a.co/d/8dhx7Tj


I have a bunch of indoor grow equipment including ballist and MH fixtures. I was looking on Amazon and found this bulb. I went ahead and purchased the bulb. I am cycling a 4ft 120 and put my fixture with this bulb and although I don't have any coral in I have live rock and liked what I saw. The fixture is an X large and the reflector is about 75% of the tank. I am just wondering if I'm barking up the wrong tree with this setup.

Below is the style of fixture and I'm able to run a fan through the fixture so it runs cooler. Running this fixture with a 1000 watt in a
12x12 room and venting the air coming from the light to out side, I was able to keep the room around 70 degrees.

I presume there will be lower light areas on the ends of the tank that will be fine for many things and the center of the tank will grow acros like a champ. What are you worried about?

I have not used these bulbs but 400 watts of light with a blue spectrum will grow clams no problem, and everything else.

Thank you, I took par measurements with the light just sitting on top of the tank,it will be higher up when used, and found usable par throughout the tank. I will do this again once the canopy is built. I will build the canopy so I can either use the MH or my T5 fixture. It will be in my build thread.

And my biggest concern was the bulb itself. Being only 30.00 compared to the 100.00 for the most popular bulbs that no one has any more. My parwise light meter also has spectrum analysis and the bulb looks like my T5 light set up with high blue but way deeper in the Actinic range. The green and red spectrum looks a little higher than the T5 by about 25% but is a lot smoother and almost flat. My T5 fixture is 4 B+ 1 coral+ and a true actinic.

Those bulbs have a bad reputation for reliability. Not sure with the mogul based, but the double ended bulbs are made with thin glass and sometimes just pop + break. I found the color and par very nice on them though. For the price you could run them and see what happens. Just keep it covered in a pendant or fixture with uv cover so it can catch the glass if the bulb shatters.

FYI aquabrite solutions makes their own line of bulbs that are great around around $60 or so. They look almost identical to a 20k radium side by side.

The fixture does have a sealed uv glass hinged bottom. This is what will make it so I can blow Air over the bulb and vent outside to keep everything cooler.

I use these bulbs, coming up on a year mark soon. Good bulbs. Except price is a bit higher since I got them a year ago. I think I paid $70 for 4 bulbs

Thank you, not too orange in color? I don't have my coral in the tank yet, so I won't know myself until next month. It's still cycling
