250 Watt 13000K Metal Halide Bulb - MegaChrome Marine, Double Ended


MB6612

This item has been discontinued.

Giesemann Aquaristic

We offer a wide variety of Metal Halide bulb choices to suit your aquarium lighting needs.

Most of the MH bulbs in the same wattage format can be interchanged. However, please contact us to make sure.

The K at the end of color rating for each bulb stands for Kelvin. This is a measurement of the color temperature. The higher the Kelvin rating, the cooler (bluer) the color of light given off by the bulb. In general, the color given off by the 10,000K German is interpreted as being a perfect white color.

NOTE: Double ended bulbs should always be used with the UV shield (supplied with most pendants). You and your corals can suffer from excess UV radiation otherwise. The bulb should be handled carefully as well since it has no outer glass casing. Using soft gloves is a good idea to keep finger prints off bulb. This is during installation and replacement.

This is a very bright bulb. It is white BUT bright colors do come out with this bulb. I highly recomend for ppl that dont want a blue tank but want colors to pop like the blue bulbs do.

“Megachrome is Megagood”
5.0

Have this in a marineland pro fixture and love it, no humming! I have a 20" ritteri right under in about 10" away and it has picked up more color with spectrum.

“Sweet lighting”
5.0

Have this bulb in my 24" Giesemann Infinity. Puts out a clean and crystal clear bright white light with some minor blue hues. Makes the tank shimmer at all depths within my two foot depth reef. The corals had to start out easy with this light, but now they seem to respond really well to the bri...Read More

“Great With Two Notes”
4.0

I have the same fixture running with the 10000K's and much prefer the bluer look. The two warnings are that the lights on the leg stands make it very hard to get your arm in th...Read More

“Very warm”
5.0

I have been using this light for close to a year now. I recently added it to a larger tank with multiple (and more expensive) halide lighting. This bulb was much warmer and really brought the color out in my corals. It is in the middle of a three bulb halide system and puts the other bulbs to shame....Read More
