## Description

desertcart.com : GXILEE Aquarium Light Timer and Dimmer, 5.5mm x 2.1mm DC Barrel Connector, 6/10/12 Hour Auto On/Off, Brightness Control 10-100%, Sunrise Sunset Simulation for Fish Tank 12-24V DC LED Lights, 2 Pack : Pet Supplies

## 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.
