I was at the Millpond in Marianna Fla. last week. I sent my sunspot mr11 10w hid back and had it refitted. I never cared for that bulb because mine always had a hole in the middle. My old AUL 10w hid MR11 (6 degree) is much better than the sunspot. In Twin Cave I had a chance to compare the LED 700 upgrade to several back ups and the focusable DR 10w HID. The LED 700 blows the old sunspot away. Compared to the focusable DR it was more than bright enough to run with it. The focusable DR had a better beam as far as "punch" and light in the center of the beam. My opinion, I really like this light. If I need more I will have to get a bigger light, but it is a much better light than the sunspot and I am comparing apples to apples. The upgrade is very affordable and if you have the sunspot I would do it. If you have a regular W/A MR11 bulb, you may want to compare the two first. LED technology, being what it is, means less replacement of bulbs, or ballasts, so the LED makes sense. If you "need" the extra punch, than you may want to wait. I have both so I have a choice, but I am thinking the LED will be with me most. Mark
