To rotate the separate heads takes a little planning. With quick rolling brownouts, they seem to remember the settings. With actual power outages, i did have to reset the timer function.

Perform well. Casts the light well, so plants get even coverage. No hassle from amazon or the seller. This light is an exceptional value.

The security sticker had been removed. Suddenly will only work at 25%. Cycled it off then on and still no light. Their customer service is not responsive. Go with the spider farmer 1000.
