How long do metal halide bulbs last for reef tank?

How long do metal halide bulbs last for reef tank?

Valuable Member. I would say 12 months and stagger the change.

What is the metal halide light ideal for?

Uses. Metal-halide lamps are used for general lighting purposes both indoors and outdoors, such as commercial, industrial, and public spaces, parking lots, sports arenas, factories, and retail stores, as well as residential security lighting; automotive and specialty applications are further fields of usage.

What color light is best for a reef tank?

Saltwater aquariums are lit using primarily a mixture of white and blue colored light, at least that is how it appears to our eyeballs. While some hobbyists prefer a whiter look and some prefer a bluer look, the reason we use this color of light is important.

What light is best for corals?

For optimal coral growth, you will generally want a full spectrum of light that includes some reds, oranges, and yellows, but that is heavier towards the blue range. There is a current trend in the hobby towards very blue, nearly dark aquariums, with glowing corals.

Do metal halide lights need ballast?

Metal halide (MH) ballasts are required to start the lamp, regulate the lamp starting and lamp operating currents, and provide appropriate sustaining supply voltage.

Why do metal halide lamps have a restrike time?

Metal halide (MH) lamps do not achieve their full light output immediately after starting. Rather, they require a period of time-1 to 15 minutes-to reach 90% of their full light output. This period is called the warm-up(or run-up) time. After a lamp has been on for a period of time and then extinguished, it cannot be immediately turned back on.

How many lumens is a 70 watt metal halide?

So, a 1000 watt metal halide bulb can produce 50,000 lumens to 100,000 lumens. Similarly, a 400 watt bulb of metal halide produces almost 24,000 lumens to 44,000 lumens. Now, what about LED lights? An LED light has an efficiency of 140 lm per watt which is about 130% more than metal halide lumens if you make a comparison.

How to troubleshoot a metal halide light fixture?

fixture or track is within +/- 10% of rated fixture/ballast voltage. Correct the voltage problem. 2. Check if fixture is located in a higher than normal temperature area (near heating ducts, etc.) which can cause the fixture to be hotter than normal and cause the ballast thermal protector to function. Move the fixture to a cooler location 3.

Why do metal halide lamps require a ballast?

Why do metal halide lamps require a ballast? Metal halide (MH) ballasts are required to start the lamp, regulate the lamp starting and lamp operating currents, and provide appropriate sustaining supply voltage. (See ” What are warm-up and restrike times for metal halide lamps?”)
