Bests & Worsts Reviews from Amazon

Seems like a quality product. Super easy to install. Cut 2 holes and screw it to the furnace. Don't be stupid like me and plug it in while installing it. These bulbs must be VERY POWERFUL as after a short period of exposure I burned my eyes. A few hours after admiring my handiwork and cost savings (HVAC company quoted me > $1,000), my eyes began to itch. Going to bed I felt like sand was in my eyes. Horrible night of tearing and itching eyes. For 24 hours I could not see. It all cleared up, but wow, that was stupid. Don't be like me. Don't plug this in while it's outside.
