I have purchased this lamp several times for my crested gecko aquarium. It's timed to turn on and off throughout the day to provide natural light and doesn't give off as much heat as other bulbs, which is a plus as my pet needs temperatures between 68 and 78 degrees. I've found that it helps the aquarium not smell so bad and it didn't appear to have any harmful effects on my pet. But it's hard to find, so I order from Amazon.
