The design is compact and easy to use, just plug it in. There’s no adjustments on it like thermostat or dimming. And it can only hold up to a certain watt of bulb. I find that it runs through bulbs quicker than other lights I have but it gets the job done.

Love these! They work perfect for my smaller tanks. They are easy to set up and change the bulbs out. Have multiple and never had an issue. 100% recommend.

I have used these for years and Im never left disappointed. I haven't had one burn out or cause any concerns when plugged
