Glad these are around The wattage of these bulbs is 18, which neither HD or Lowes carry, they both have gone to the wimpy 8 watt. I was glad to see Amazon had these and though they are more wattage than what I was previously using(12) I have enough room on my transformer to accommodate them.Good: they are bright, might be too bright for someBad: can possibly cause you to overload your system, check the wattage on your transformer and then add the watts of all the bulbs to make sure that they dont exceed the transformers rating.Bottom line: great to use as a replacement for the bulbs you used to be able to get as long as your lights are spaced enough, otherwise it may be too bright.

I bought these and should have done a little more homework before hand. They do fit my light fixture and they do work well. However, if I had bought the xenon light from HD I would have bought one light that lasts 3000 hours and paid half as much. I bought 4 lights that in total only work ~2250 and paid twice as much. So I paid twice as much and got 750 less hours out of it. Next time I will buy the other light if still not offered by amazon.
