THE GOODD, I've now had this light for just over 2 years. It is on my 48" salt aquarium. Super easy to install. unbox, adjust the extenders to your tank, plug in and set your timer via the remote. The light is great and the remote controller is fantastic to set your on and off time. You can program all three colors separately. So a delayed ON-TIME and then a delay off time to mimic natural daylight. With the blue light you can fade to moonlight for an hour or two before gong dark. I set this up twice and never had to worry about turning my lights on or off again. THE BAD: the light power cord has an easy separator as most LED's do. when i clean my tank unplug at the separator and stand this aside. After about a dozen unplugs the prong in the separator is sensitive as to whether it makes the connection. SO, FOR ANYONE that experiences a FLASH when you turn it on and then nothing this is why. The light still works, don't toss it!!!!!! You may need to play with the connector or wiggle it a bit and it will be good to go. I lost power once and had to re-program the timer and it took me about 10 min to make the proper connection. but it came back and never had to touch it again. That is the only flaw I find, but I may have bent the connection prong myself. I use it over the HOOD plastic cover and also have a glass evaporation barrier under it so it really gets no condensation like others have mentioned. I would buy this light again if needed. It is a great light otherwise.

The light was not bright enough and the colour of the light was not so good I no longer use this product. Great for beginners at the price
