Possibly, if the ballast is suitable. Get the wrong ballast and your bulb will not be driven to the right colour temperature or maybe even blown.

I have used such 'industrial use' MH before and they cannot hold a candle to the proper aquarium MH pendants somehow... they were much dimmer even though they were the same wattage. I narrowed it down to the ballast.

So that means changing the ballast as well ....and I guess the suitable ballast wud cost much more than $30 dollar

i have a Wall mounting enclosed Tungsten Halogen Floodlight casing. I know halogen not suitable to marine but can I use the casing to modify into MH??

First thing that floodlight came to my mind are those search and rescue light onboard ships. I hope that is not what you mentioned, if it is, prepare to have cooked seafood for dinner even with chiller. (its burning hot, one cannot stay too near or under the light for long)

haah the one i saw is those people put for ponds.. landed property.. those type.. square one.. i dont see any ballast leh hha not sure.. quite small and compact thot can use for my 2ft..

the bulb is yellowish

if i change to the marine type how much it cost???

[ah wa!]

When you mentioned that it cost only $30, I've suspected that it was a halogen light instead of metal halide. A halogen light does not required any ballast to operate.

yah its halogen.. but can use?? the tube can change?
