Hot Spots??....................

I see these mentioned all the time but cant find a defention.
can they be a problem with low temp CFL lightbulbs?

My walmart emergency blanket is NO WHERE near flat against my walls. Couldnt find mylar in my area.

Thanks~!

You don't have to worry much with CFL, unless you get into the real high wattage ones. Just make sure they stay an inch or two away from stuff.

I believe hot spots can only be caused by HID's. I've had them. There is a diffuser out thats about $30. I plan to use one next time to evaluate. As for definition??? I guess I'd say it's a spot where the plant receives too much light concentrated on a small area. You would probably only see this with 1000 watters.
