I’m an artist and sometimes I dry my paintings in the sun. I find myself in the winter climate this year, with less sun available, so I thought there has to be a UV lamp esp for paint. I was happy to find out they exist, and thought this hand-held lamp was suitable for my paintings. Using it for the first time... To my amazement I only had to hold it for a few minutes in order to bake my paint dry. I could see the vapors of water rising off my canvas. I hold it about 2 feet away. Just like the sun. Now I don’t have to wait hours for my paint to dry. It has worked great. Because it’s a bulb, I recommend handling it with care and limit banging it around.
