Review: Useful, easy to set up, and works! - Really useful product - It doesn't have a high level of customizability, but does what it's supposed to do, which is automate non-automated lighting for a cheap price. Basically, you turn it on at the time you want it to turn on every day, set how many hours it should be on, and it repeats that every day. Easy and effective. These worked just fine in-line with both an Aqueon hood, and a Topfin branded hood. Most of my tanks, I just use separate 24/7 timed lighting bars, and never even plug in the built in hood lights - this makes the built in hood lights useful again, and there's value to that!
Review: Simple but great value - Very simple but effective timer. You turn it on and select your ON duration and it’ll turn off when you asked and repeat the cycle from whatever time you turned it on last. There’s no timekeeping display but so far it’s been keeping time just fine. I didn’t look into compatibility but luckily it connected fine with my existing hood light. I also didn’t need more than one of them which makes the price an even better value.

## Features

- Programmable Timer with 3 Modes: This fish tank light timer offers 6, 10, and 12-hour cycles that repeat daily once set — choose 10 hours at 8 AM and it turns on every morning at 8, then gradually dims to simulate sunset by 6 PM. Ideal for freshwater tanks, saltwater reef setups, and planted aquariums that thrive on a consistent day-night rhythm.
- Beginner-Friendly Setup: Press the timer button to cycle through modes — 1st press Yellow (6 h), 2nd press Green (10 h), 3rd press Red (12 h), 4th press cancels the timer. Color-coded LED indicators let you confirm your setting at a glance, so no guesswork even on your first try
- Designed for Aquarium Hobbyists: Whether you keep a betta tank on your desk, a shrimp breeding setup, or a 75-gallon reef, this LED light timer turns a basic tank into a professionally lit aquatic display. A go-to tool for aquascapers and fish keepers who want their livestock on a healthy photoperiod year-round
- Manual On/Off Supported in Timer Mode: Timer function stays active (no auto-cancellation) unless you intentionally press the timer button to disable it. Next scheduled on/off time adjusts automatically based on your manual activation (e.g., set to turn on at 8 AM, manually activate at 7 AM → subsequent cycles shift accordingly)
- Wide Compatibility: Features a 5.5mm x 2.1mm barrel connector that pairs with most single-channel aquarium LED fixtures running on 12-24V DC. Compact size (3.9 x 2.8 x 1.2 in / 10 x 7 x 3 cm) tucks neatly behind your tank stand. Low-voltage design keeps the setup safe around water and livestock.

## Questions & Answers

**Q: Do I need to set how many hours I need in the morning?**
A: Our fish tank timer offers three default timer modes(6, 10, and 12 hours). You set the timer at the hour you want the light on, and the timer will turn the light off after the set amount of hours.

**Q: Does it come in automatically everyday after setting the time initially?**
A: Yes. If you set the aquarium timer to 10 hours at 7 o'clock, it will come on daily at 7 and go off at 5 in the afternoon.If the power goes out or it gets cut off for any reason, the settings will be lost until you reactivate it.

**Q: Can the timer switch other colors of lights?**
A: No, the aquarium light timer can only adjust the light brightness. It can not change or switch the color of the light.

**Q: What lights does this timer work with?**
A: It will work with any 12v-24v LED light with the same 5.5mm x 2.1mm barrel connector
