NICREW Aquarium Light Timer&Dimmer, Easy to Program Fish Tank Light Controller

This little switch does its job masterfully. (Tip: This switch lasts about a year, not bad at all for an $11 part. No need to buy a new aquarium lamp every year . The lights themselves will last much longer than that. Just buy this switch! This part, and the lamp, AND this company, HIGHLY recommended!

This works well so far, we shall see how long it lasts

I wrote very positive or very negative reviews only generally. This is a bad one! I have purchased two of these exact same pieces now, the first on December 13, 2022, and the current one on February 8, 2024 - BOTH HAVE BURNED OUT ALREADY! I bought the same one again, only because this piece has good reviews, and I suspected I just was unlucky and got a lemon! Nope, as both have burned out way too fast! I highly suggest you buy something else. To answer the obvious, neither have gone into the water, because I have made sure that would not happen; neither have been pulled on, so the cords were fine as they are tucked out of the way - they simply stopped working! I will never buy this fish tank light timer ever again, as it has clearly been a waste of money! I highly suggest not buying it! I even went back to check on the ratings just now, and was surprised to find them still getting a 4 star rating with 811 reviews just a moment ago! I like the concept, the ways it works - when it works, but it has poor quality electronics, and fails way too easily! Buy a different one!

I love this aquarium light timer! It fits perfectly onto my Aqueon LED hood, and the best part is the gradual dimming feature. Instead of suddenly turning on and startling my fish, it slowly brightens in the morning and dims at night, creating a much more natural transition. It’s a great product, easy to use, and makes a big difference for my tank. Highly recommend!

May 2025: beautiful in it's simplicity. plug it in. choose a timer setting. set it when you want it to start. that's it. and less than $10. My fish haven't said much, but i think they will love it Oct 2025: it failed after 5 months, but i like it so much i ordered it again

Love but has to be reset in power outage

I bought two of these in around March and in December one of them stopped working. They work great when they work, but it giving out bothered me. I’ll probably buy again as they are decently easy to use and they are compatible with my lights.

This product would be great, but it only lasted a little over 5months. Purchased July 2, 2025 and went December 14, 2025. I didnt even get 6months out of it.

Works great! Bought 2 for my lights that only had 1 setting and no dimmer. Plus it has a timer for 8 hours, 10 hours, and 12 hours.

Awesome easy to use

Definitely better than a bilky timer. Easy to use. Preset times work just fine for my needs, brightness increments go 10% brightness each press.

This is my third Aquarium Light Timer & Dimmer. It’s easy to set up, easy to use, and when it works, it performs well. I bought the first one on July 30, 2024, but after an electric outage it stopped working, so I had to replace it on March 25, 2025. I then decided to buy a third one on October 11, 2025 for a different aquarium, believing the first failure was a one-time issue. Unfortunately, I was wrong. The same thing happened again—it suddenly stopped working. This unit only lasted three months. At this point, I’m very disappointed with the durability and reliability of this product

Love it! Works with Aqueon Opti-bright LED.
