Aqueon Preset Heaters require no adjusting! The preset temperature has been calibrated to 78°, appropriate for most tropical fish. The fully submersible heaters are constructed of shatter-resistant quartz glass and features an automatic safety shut-off to avoid overheating. An LED indicator light displays red when actively heating.

I purchased 2 of these lights to go on a 40 long tank and I like the look of the lights sitting above overhead the tank.
Of course they have 2 settings one which is a soft blue for evening.
The quality and price have pleased me too.
Guppies loved it and I think my puffer will need a few more tries to take to the frozen daphnia, but she’s a diva about all foods until she’s tried them a few times.
