I bought this light when I purchased a mega grow kit. I used the oven method to inoculate with this light providing additional sterilization. I used the light on all my surfaces before starting, on each jar top immediately before inoculation, and on my spore syringe needle after flame heating while letting it cool. The light was wrapping in a layer of aluminum foil and wedged between my top oven rack and the top of the oven. I fully expected the light to suffer or quit working afterwards due the the heat, but it pulled through like a champ and used about 40%, from around 75% to 35%, battery life over the 30 to 40 minutes it took me to inoculate my jars. I also plan in using it to provide added sterilization when I prepare agar plates and slants for long term storage. My inoculation was 100% successful in all 18 jars. I would highly recommend this light for anyone to provide added sterilization during any project. My final note is high prize for having a rechargeable battery, this keeps me from having one more thing I need to keep track of having batteries.

I recently bought this after losing a batch to mold that I didn't know how to get rid of. I'm new to the UV sterilizers and can't say much in comparison. This particular one has four settings, 5m, 15m, 30m and SE. The time settings speak for themselves but the SE setting seems to be running indefinitely. It auto shuts off if angled upwards to protect eyes.

The first one I received didn’t work - I called customer service and had a replacement within a few days - friendly and no hassle.

This thing works great! Was able to kill mold on 1 jar i had mold spot.... lid accidentally popped open.. split second , had mold!! Few days later..light saved jar!!

I received the portable UVC light just a few days after ordering. Light is portable and easy to use. I like the preset timers. My sister also bought one after seeing mine.
