The timers are very easy to use. They throw off plenty of light. The clamp is very strong, but it was too small of an opening for our table. You can improvise and attach it to a sturdy flat object under your plant. We are using them to grow seedlings and are running them 8 hours at night.

These are the real deal. They're the same ones sold at the big name stores but for over $20 less per ballast. Great buy! I've purchased these multiple times and haven't had a bad one. I'm about to purchase again

Great grow lights! My tropical orchids love them!

I'm using this light to start normal garden variety plants, the tomatoes and peppers are showing increased growth in just one day (14hrs) of use.

I had to put it very close to my plants. Not enough light

This light assembles easily but it can get tipped over without much of a bump, due to the weight distribution at the top. It’s manageable. The timers are fantastic. I bought two and may buy another.
