Alidou 7-Row LED Aquarium Light, 32W for 24–30 in Planted Tanks, Programmable 24-Hour Cycle

Alidou Advanced 7-Row LED Aquarium Light is a programmable freshwater planted-tank light with an automatic 24-hour cycle and adjustable fit for 24–30 in (61–76 cm) tanks.

• Automatic schedule covers 24 hours in 18 periods — follows a programmed progression from daytime light to nighttime blue light and then off.
• DIY, Day, and Night settings — choose custom time ranges, brightness, and available light colors.
• Seven LED rows with 182 LEDs and 32W output — combines white, RGB, blue, red, and green LEDs for freshwater tanks.
• IP68 waterproof rating and a 1.2 cm (0.47 in) aluminum shell — designed for water exposure and heat transfer.
• ETL-certified, separable low-voltage DC adapter — includes an AC/DC adapter and adjustable metal brackets.
• Wired clock controller with an automatic on/off timer — set the schedule to local time and see the current mode, color, and brightness.

This light is made for freshwater planted aquariums where a consistent daily lighting routine and adjustable color are useful. Its automatic cycle provides a preset progression, while the custom modes let you tailor the timing and light settings to your tank routine. The wired controller brings the clock and controls together, so the scheduled operation can be set directly on the unit.

How does the Alidou aquarium light’s 24-hour cycle work?

The automatic rhythm mode divides a full day into 18 periods. During daytime periods L1–L13, the light changes color temperature and brightness to simulate sunlight from sunrise to sunset. At night, L14–L17 shift blue light from bright to dim, and L18 switches the light off.

The controller’s clock keeps time for the programmed schedule. Set it to local time so the automatic lighting cycle follows the time you choose; the light turns on and off when its programmed times arrive.

• Four working modes can be switched with one click.
• A red indicator shows the current time, mode, light color, and brightness.

Can I adjust the light’s timing, color, and brightness?

Yes. The three custom modes are DIY, Day, and Night, with freely adjustable start and end times. DIY mode has five periods across 24 hours: set the times, color, and brightness for L1–L4, while L5 is the off period.

Day mode uses white light, with brightness adjustable from 10% to 100%. In Night mode, choose red, orange, yellow, green, cyan, blue, or purple, then set brightness from 10% to 100%. Together, the seven Night colors and white Day light provide eight color options; the product also offers 10-level dimming.

• Ten setting buttons provide direct access to the controller’s adjustments.
• Start and end times can be set for Day and Night modes.

What tank size and lighting specifications does it suit?

The light is intended for freshwater aquariums with a tank length of 24–30 in (61–76 cm). Its seven-row arrangement contains 182 LEDs: 118 white, 28 RGB, 12 blue, 12 red, and 12 green. The white LEDs are rated at 7000K, with a color rendering index (CRI) of 90; total light output is 2200 lumens.

The 5054 and 2835 LED beads produce white light that the manufacturer says is similar to natural light and flicker-free. The lighting is designed to promote aquatic plant growth and make plant colors appear lifelike. For fit, compare the aquarium’s length with the stated 24–30 in range.

• Power: 32W; input: AC 100–240V; output: DC 24V.
• The IP68-rated light is designed to withstand splashes or accidental falls into water.
• The 1.2 cm (0.47 in) aluminum shell supports heat transfer.

What is included, and how is the light controlled?

The set includes one LED light with a wired controller, one AC/DC adapter, two adjustable metal brackets, and one user manual. The adapter is separable and ETL certified; it is a low-voltage DC adapter, with the manufacturer identifying energy efficiency as a feature.

The controller has a clock for the 24-hour settings and uses its buttons to select a working mode and adjust the schedule or light settings. The power cord is supplied in two sections measuring 2.1 ft (0.64 m) and 4.9 ft (1.49 m).

• Included components: LED light and controller, AC/DC adapter, two brackets, and user manual.
• The adjustable metal brackets are part of the included setup components.

The Alidou Advanced 7-Row LED Aquarium Light suits freshwater planted-tank owners who want an automatic daily lighting rhythm with options to customize the schedule, brightness, and color. Its fit is intended for tanks 24–30 in long, with a clock-controlled cycle and three additional custom modes.
