Ok so im in my second season with my 30' AG Pool and its been great, but unfortunately while draining it down before winter, which I was doing at night and kicked the light on to help see the water, which was a bad idea, because now the bulb is burnt out. (i know my fault) anyway, what im wondering is if anyone knows what bulb this thing takes the only info I can find in the book is the bulb assembly, this doesnt look like what I need, but the whole entire unit where the bulb goes. If anyone knows it would be greatly appreciated, also recommendation where to buy, because my pool store is over 60 miles away.

TIA
Phil
