150 Watt 17500K MegaChrome Crystal Metal Halide Bulb - Giesemann, Double Ended Information

MEGACHROME crystal - the perfect light source for all marine aquariums that need a strong light performance in combination with a high blue/violett ratio.

The MEGACHROMEcrystal metal halide bulb offers excellent coloration and high intensity. It is crystal/crisp-white with a light violett/blue tint. It brings out the fluorescent pigments in corals nicely. Fluorescent supplementation is usually not necessary, but can be used for added intensity and to simulate dawn and dusk.

The light spectrum has a pink accent and shows fluorescent effects on many corals which gives a completely different impression of the colour. The very high colour temperature of this bulb is achieved through a special manufacturing process which at the same time guarantees a long colour stability which is a problem with many bulbs towards the blue end of the spectrum. The lifetime of this brand-new bulb generation, due to the innovative technology, will be over 3 years, prooved by several tests.

This bulb contributes to a healthy growth of your corals and produces stunning colours in your reef aquarium. An excellent choice for reef tanks with SPS and LPS corals.

Comments: I am very disappointed with these bulbs. On the plus side they are much brighter than the XM’s they replaced however they are very yellow. My tank, 120 gallon reef, has never looked this bad with any other bulbs. They have only been in place for a few days so I am still hoping they will change and I don’t have to throw over $200.00 worth of lights in the trash. Grading these bulbs as 17500K is a complete misrepresentation as I have not seen even a hint of blue or violet.

Comments: I bought these bulbs to replace my old XM 15000 bulbs. The 17500 have the same color. My SPS corals love them and they are growing like crazy. I did, however, have to move some polyps down lower. The bulbs have 6 months of use now and they're still strong...will buy again. They're not yellow in my icecap lighting system... THEY ARE PERFECT!!!!!!

Comments: I have a SPS dominant tank. I've been using Pheonix 14K bulbs for a year now. Thought I would try out the Geismann because I love their other products. 7500K color temp!!! They advertise 17500K. Completely yellow. I don't want a neon blue tank, but this is ridiculous. They may grow coral, it's too early to tell the coral response, but a complete waste of overpriced bulbs.
