You're going to like it! A few notes:
1. $60 at Home Depot, $30 for the smaller 300 Watt equivalent one (uses 38 watts, 4,000 lumens).
2. This one is so bright that it is better higher up on our garage ceiling. A store employee told me that they had one on display at eye level and had to remove because customers complained. I put the 300 Watt one in our basement with a lower ceiling, but you still don't want to look directly at it too long.
3. It's been a little below freezing here and it hasn't affected it.
4. It comes on immediately, but the one in the basement has a one second delay.
