Hagen Fluval Prism Multi-Color Underwater LED Spotlight

Pros: Price, Tiny, bright, strong suction cup, remote sensor on transformer and not in tank, black and not white, easy to conceal, more angle options with the original due to sensor placement, no sharp edgesCons: Chord could be a little longer (about 36"), RGB white and not dedicated white led, inability to daisy chain on one remoteThese lights are great. I have one of the original, white ceramic, version of this light and I like it but it's too big and hard to hide to be used in many places in my aquarium. These lights the remote sensor is on the transformer so you can actually hide the light in a feature in your tank and still be able to use the remote. The lights are really small, about 1.5x1.5 inch. Very easy to conceal in the tank. The only issue I have is that the white light is RGB and not white LED so you can see 3 distinct colors when it's in white mode. it would also be nice to have a longer chord for those with larger tanks looking for bottom installation, but all things considered these are a fantastic product. build quality is great, no sharp edges to hurt fish during psychotic episodes and no little places for things to hide in.Overall these are a great revision of a cool product that makes it more flexible and less obtrusive. And they're cheaper. Well done little Chinese dude, well done.

Fluval Prism 2.0 is almost everything I was dreaming about for my planted tank:- bright, yet tiny (easy to hide)- colour and brightness adjustment- fun pre-programmed light cycles (everybody loves a stormy effect in their tank once in a while, and Prism gives you the whole two!)- tolerable light spillage (this is a spotlight, not a flood; great for highlighting small areas of the tank)- out-of tank sensor for the remote (makes it much easier to control my Prism)Sun option turned out to be great for growing dwarf baby tears carpet, which I was struggling with before. After just 10 days my previously melting plants are happily growing and spreading. I plan to add one more in my tank to provide better light for other light-demanding plants.All in all, it's a perfect tiny light for my needs. If I were to change something it would be adding a scheduling option or something like Finnex's 24/7 programme. (But I guess in this case it would not cost $35.) I am considering adding a Fluval LED controller to imitate day/night cycles.

The reason I'm giving this light 2 stars is because there's literally NO WHITE COLOR....The price is TOO HIGH for a few colors that don't really match, the only colors that match are the red, green and blue. The only good thing about it is the lightning 🌩 effect, which makes up the 2 stars. I hate writing bad reviews really, I rather not, but I got an email to write one, so here I am. I have a Fluval gravel cleaner which I'm not happy about as well. The only Fluval item I'm happy about is the Breeding box I have.Review UPDATE: I increased to 3 stars because you actually CAN turn it around. Since it was new, it wasn't moving much and I didn't want to break it, that's why I thought it wasn't moving, but today I was cleaning it and I was able to turn the light in different direction.Update, April 11th 2022. I forgot to write an update earlier. Sometime in January 2022 this led light shows completely different colors to what you select. But not by pressing red, but blue coming on. It's more like all the colors are completely messed up. It is a total malfunction. This product is a total failure. Shame, it looked nice when it worked, but was never worth that much money, since the white color was never really white, but a bunch of multiple colors together that gave a slight white color. Changed it to 1 STAR.

It has multiple colors that may possibly combine to be a white light but in my tank all I see is the rainbow. I've changed it to be an orangish color which works better for me than the rainbow "white".And yes, I am pressing the white light button on the remote.

Let’s be clear: this is a fancy light, not something that you will use as a primary tool to light up your whole tank, especially if you have plants in there. But, i must admit that it’s pretty cool. I don’t see 80 different colors tho, for me there’s no more than 12 colors and it’s way enough since most of them are not really usable unless you want your fish to have a little party :)Pros: the wattage is very low while the light is pretty bright. It’s a nice addition to your show tank, especially if you hide it behind a pile of rocks.Cons: there’s no white, it’s a clubby blue/red/green instead, looks very fancy but kind of cheesy after a while.

You get 20 colors including the sunrise, thunderstorm 1, thunderstorm 2, and rotating colors buttons (there is no way you get 80colors as the package suggests). That said this light easily projects across a 4ft tank.I had issues with the first one I ordered, however Fluval came through with a simple warranty process that replaced the defective light with a short turn around. The Fluval customer service exceeded my expectations.

The light worked very well and was very attractive in the tank. It only lasted for 3 months before it shorted out from taking on water on the inside.Definitely not worth the money for how long it lasted. This is a good brand and I’m surprised at the low quality of this light.

Fun little spotlight! The lightning affects seem to freak the fish out but other than that it’s great! Just adds a little extra to the tank…
