good for a long long time
Your review: My amps that have lasted over 35 years. They get hot so give them rest time and turn them off. However, the light is the type of light that gives you natural light and a perfect color and does not distort or change color. The halogen bulbs are good for a long time. Marvelous.
Pros: GREAT white light which is Perfect for doing artwork of any kind especially color work.
Cons: They are halogen so they get hot. You must turn off periodically to cool them. You endure the safety and longevity by doing this simple act.
