Submersible Aquarium Lights for Fish Tank, 24/7 Cycle Fish Tank Light with Timer, Full Spectrum+7 Single Colors, Auto On/Off, Adjustable Brightness, 10W (38cm)

Fab little light, offers a more versatile colour range than my other aquarium lights. Really great build quality and it does what it says on the tin.

When turned on this light is very impressive. Illumination of the fish tank is top notch and the colour range is great. The only let down is a very poor instruction manual and awkward timer set up. Two days in and still yet to have this item working on its timer

Not entirely sure how I managed it, or if I could do it again but I've currently got this working on its 24/7 mode on a 12 hour cycle and it's very impressive. Stumbled across a guide on YouTube but can't comment on the accuracy of that because I'm not touching something that's not broken! Have bigger tanks and would buy the same for them if these came larger.

It's only been one day and so far, very good. 24/7 setting is nice, dimming at dusk. Easy to set up,instructions easy. Nice lighting for aquarium.

Arrived on time. Very pleased. The only complaint I have is the writing is so small, it’s hard to see how to operate the different light settings. It’s a bit of Pressing guessing but in all very pleased with the light settings, I do get my tank looks lovely

Bought to replace an older style standard led that failed, and so far the fish seem much happier with the perfectly controlled 24/7 cycle. The light itself is very well made, and the slim profile means it's unobtrusive if you put it in the tank. I have mounted mine above the water line though, because there is no way to mount the light pointing downward if it's in the tank. That's the reason for dropping a star. The sucker mounts are very good, strong suction, but, unlike others I've seen, cannot turn the lamp 45 degrees to allow a side mount with the lamp pointing downward. Overall though, fabulous for the money. Jets see if it lasts as long as my old one (5 years).

I'm not sure who writes all these reviews,the light aspect is good but the instructions are useless and don't bother buying it I'd you don't have perfect eyesight because you won't be able to see what any of the buttons do !! I've been trying to set the 24/7 mode for hrs and it's still not right :/

This light is amazing the 24/7 timer mode is great. Turns itself off at night but changing to a blue colour and then getting dimmer and dimmer until it turn off completely, on a morning in comes on with an orange glow getting brighter. Colour help to simulate dusk and then sunrise. My fish tank is in my bedroon so is perfect.
