Water cooled lamp fixtures

The bulb probally and the fixture probally break due to expansion when the water quits recirculating, making it stagnate in the fixture, boil, and crack the inside glass. Then water on the bulb and boom there it goes.

If you can afford water cooled fixtures then you think you would be able to afford a temp. shutoff to cut off power to the ballast if the temps rise to fast.
If your in a hot climate and yourlooking for a larg resevoir to use for your recirculation why not use your pool as your res? It would even keep the pool a little warmer :idea: no drain to waste. :)

Water-cooled and air cooled lamp fixtures are continuing to grow in popularity especially in hot climates. Lamps run cooler and can be moved closer to plants. Water-cooled bulbs are difficult for thermal imaging equipment to detect (fawkin feds) Air cooled fixtures are inexpensive to operate and easy to set up. The plastic shield around the bulb also lowers light output by as much as ten percent.
By using a cooled lamp marijuana growers will decrease heat by 80 percent with a properly set up watter cooled bulb. The water and outer jacket account for a 10 percent lumens loss. Growers make up for the loss by moving the bulbs closer to the weed plants. On an average day, a 1000 watt bulb uses about 95 gallons to keep cool, if the water runs to waste. To re-circulate the water requires a big, big reservoir. The water in the reservoir must also be re-cooled. Reservoir coolers can cost $1000 upwards. Cooling the reservoir can also solve many of your heat related problems when living in a hot climate.
For that price the pool pays for itself...note to self, buy lotto tickets :)
