Good item – Review by Lsa73@yandex.ru (Posted on 30/12/2016)
Good quality, very fast shipping, excellent item! Thank you!
Works as expected – Review by ethjzz (Posted on 08/12/2016)
I bought this product as a replacement of lighting JUWEL aquarium. The size is suitable, the equipment works well for 14 days. I hope I will have a long life ballast...
Good quality, excellent value lighting controller – Review by IainS (Posted on 04/04/2016)
This unit seems very good quality so far (it turned out to be the same make as was used in my original hood) and was easily the cheapest option I found for replacing my old broken T8 aquarium lighting system. It's very easy to install, just follow the wiring diagram and push the exposed end of the single core wires from the tube holders into the terminals on the controller. I only had to lengthen some of my existing wires. I also purchased some new waterproof T5 end-cap tube holders from Covershield which were a like-for-like replacement for the old T8 versions in the hood. I've now replaced an old broken T8 aquarium lighting system with Jewel compatible T5 tubes of the same length and the light output is awesome. You'd never know this was not the original lighting setup.

Tip: T8 Tubes are 8/8 inch in diameter (26mm). T5 Tubes are 5/8 inch in diameter (16mm). When measuring the length of your tube, measure in mm from end to end without the pins. These ballasts are to be used with T5 HO tubes(see label) and not T8 26mm.
