Can these be used in under water fountain light housings? I'm concerned that they need air flow for cooling.

I'm guessing that water would cool the bulb as well as, if not better than, air...But I dont really know. I use them in a more traditional way.

I haven't install this MR 11 in that application but if water is hitting or around the fixture housing, I'm sure that the temper of the MR11 will be regulated by the water temperature and shouldn't be an issue.

I would assume. They act just like any other MR11. And besides, these are cool. Very little heat.

The lamps are sealed and should provide wet-weather operation with no problems. If mounted on a boat trailed, they should be ok as long as they are not submerged for a prolong period.

Sorry, but no. These will increase the humidity through the evaporation of the water used in cooling. Useful only in dry conditions.

Seems like it SHOULD work as long as the build is protected in water tight enclosure. It is not a bright as a regular incandescent, but it is cooler and should be bright enoughespecially for dim lighting conditions. Don't drop the remote control in the water.

This is a perfect indoor light but should be air cooled to get the longest life out of the 600 bulb. A 1000 watter should always be air cooled.

Could be, if the flow of air is not going over the cooling area it cannot cool it down. If this part fits your cooler buy it and try, it could be a really cheap fix...

No. They are halogen prejection And I would not get these lights honestly they leak water.

Definitely not. These LEDS in these hoods have a pretty low lumen count and are pretty much strictly for illumination, not plant growth. You could grow some low light freshwater plants, but that's about all.

Probably not. The design is as bare as you can get as far as structure. Mine was falling apart. They emit a great amount of soft light but other than that I wouldn't recommend doing anything else to them. The softboxes they come with are poorly manufactured and seem to be a bit much for the weight of the light heads.

Yes you can. If you are not using liquid cooling you can even install them on the top

Hydro innovations recommends using them to cool the exhaust air from HID lamps, based on chilled water.I say its a heat exchanger. Heat your res, vioala warm air; chill the res, vioala cool air. Use it like an A/C; chill the reservoir (10-20degrees F cooler than room temp) and pump air thru it. This is great if you dont have air cooled hoods, like maybe 2-3x sun system 150 hps in a small tent, gets hot but you cant vent the air out of your lights. Cool the whole tent!

They work outside with low voltage, however, in my situation,they are protected from direct contact with water. I suspect they would still work for low voltage lighting, even if they were occasionally wet

These units are sealed so you should be able to get creative with mounting. That being said I would not submerge the light.

The fittings could be adapted but the water would move through to fast to be effective. The manufacturer is very specific about the amount of water flow over the light as too great a flow does not allow enough light exposure to the water passing around and through it. GREAT sterilizer for a medium size pond with proper sized pump.

I really don't see why not. I have mostly used them indoors, but I do have one in my garage now where it gets quite cold. They run very cool, but LED's have been used for years outdoors in Christmas decorations, so unlike the CFL's they can withstand cold temperatures.

If the fixture doesn't allow much airflow it might be an issue (especially when it's warm outside) due to overheating of the bulb which can cause it to prematurely fail. You might want to consider using a CFL or LED bulb that specifically says it's compatible with enclosed fixtures.

The 12 watt will probably not meet your needs if you have coral, but 2 would probably light most of your tank for visual purposes. I am guessing that you could only fit 3 over the surface area of the water. Depending on how high you hang them above your tank I am guessing 2 or 3 of the higher watt bulbs (I have a 54watt on my refuguim and my colt corals are thriving there) would support some corals.If you are using a Bio-cube hood these will not fit under it.
