100W bulbs

[timrandlerv10]

where can i get one?

and if that's the only light on a frag tank, whats the best color to get?

if i get a color that is growth oriented, but doesnt do much for the coral's color, will the coral's color change in a new tank over time?

thanks!

Most of 100W MH bulbs I see are mogul base pulse start bulbs. The color temp is typically 4000K. I don't know what kind of effect this type of bulb has on corals. The bulbs are relatively inexpensive. If you google for it, you will get a lot of hits.
Do you already have a pulse start ballast for it?

Double ended 70W comes in both 10000K and 14000K, but the bulbs are a lot more expensive. However, there are a lot of inexpensive ones offered on eBay. This bulb combined with a right ballast should be brighter than a 100W bulb on a poorly matched ballast.

A Viper fixture for nano tank is a complete fixture with 14K 70W bulb and an electronic ballast. I saw it as low as $158 plus shipping.
