HM ELECTRONICS Wing 2S1 Smart LED Reef Light, 12-Inch, 21W, App-Controlled

HM ELECTRONICS Wing 2S1 is a 21-watt smart LED reef light with a 12-inch (30.5 cm) strip, designed to illuminate saltwater aquariums for LPS and soft corals or fish-only setups.

• High-output OSRAM LEDs and four color channels — provide a reef-focused spectrum for viewing corals and fish.
• Independent app control of all four channels — lets you adjust the light and preview spectrum changes in real time.
• 12-inch (30.5 cm), 21-watt size for 12–18-inch (30.5–45.7 cm) tanks — supports a specific aquarium fit.
• Adjustable, end-mounted brackets — span across rimmed or rimless aquariums.
• Fanless design and IP55 water resistance — operate without fan noise and help protect against dust and everyday splashes.
• Easy Mode, six presets, lunar-cycle settings, and Acclimation Mode — offer lighting options for setup and coral adjustment.

This reef light is made for saltwater aquarium owners who want to tailor illumination for corals or fish without manually adjusting each channel at the fixture. App-based controls let you manage lighting schedules and make spectral changes, while adjustable brackets help the light fit across different aquarium styles.

What aquarium is the Wing 2S1 designed for?

The 12-inch Wing 2S1 is designed for tanks from 12 to 18 inches (30.5–45.7 cm) wide. Its reef-focused spectrum is intended for LPS and soft corals, and it also suits fish-only saltwater aquariums. High-output OSRAM LEDs deliver a balanced four-channel spectrum for reef viewing.

• Four independently adjustable color channels.
• Light length: 12 inches (30.5 cm); power: 21 watts.

Will it fit a rimmed or rimless aquarium?

Yes. Adjustable end-mounted brackets span across the aquarium, so the light fits both rimmed tanks and open-top rimless aquariums. The brackets adjust to fit tanks up to 6 inches (15.2 cm) wider than the light. Compare your aquarium width with the 12–18-inch (30.5–45.7 cm) fit range for this size.

• Other size options include 24 inches (61 cm)/42 watts for 24–30-inch (61–76.2 cm) tanks.
• 36 inches (91.4 cm)/63 watts fits 36–42-inch (91.4–106.7 cm) tanks; 48 inches (121.9 cm)/84 watts fits 48–54-inch (121.9–137.2 cm) tanks.

How do the app controls and lighting modes work?

Use the app to adjust each of the four color channels independently, preview spectral changes in real time, and schedule sunrise and sunset. Wireless group control lets you manage multiple lights together from one app. Easy Mode provides a simple starting option, while six classic preset programs include lunar-cycle settings. Acclimation Mode helps ease corals into a new lighting schedule.

• Set scheduled sunrise and sunset transitions.
• Use the fanless construction for silent operation; IP55 water-resistant construction helps protect against dust and everyday aquarium splashes.

The Wing 2S1 is suited to saltwater aquarium keepers who want app-controlled spectrum and scheduling for LPS or soft corals, or lighting for a fish-only tank. Its 12-inch strip, adjustable brackets, and four-channel controls are designed around aquariums in the 12–18-inch size range.
