Plus the instructions come in the box will tell you how to operate the device. The automatic feature is very useful in any event though **Q: What is the size of the light body? I want a light to put in an aquarium hoid yo replace an existing light. I need something that is 3¾x 21"** A: My light is 4 inch wide x. 17 inches long and about 3/8 of an inch thick. It fits nicely on a standard 10 gallon tank with about an inch on either side. **Q: Would this light fit a 20 gallon long that isnt rimless?** A: If you purchase the 22 watt or the 26 watt it will fit. A warning to those wanting aquatic plants - this grows algae like crazy but every plant in every tank I have this brand of LED light on has died or is barely struggling to hold on. So I wouldn't recommend it for planted tanks. **Q: I know I can adjust the light intensity in manual mode but can I adjust the daylight intensity when it is in auto mode so it isn't always 100%?** A: By auto mode, you mean S1? The brightness is one of the programming options for this mode. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***E on February 12, 2026* ### ⭐⭐⭐⭐⭐ Review *by S***N on March 22, 2026* ### ⭐⭐⭐⭐ Review *by E***V on April 2, 2024* ## Frequently Bought Together - hygger Auto On Off LED Aquarium Light, Full Spectrum Fish Tank Light with LCD Monitor, 24/7 Lighting Cycle, 7 Colors, Adjustable Timer, IP68 Waterproof, 3 Modes for 18"-24" Freshwater Planted Tank - H2Pro 20" Glass Canopy 10 Gallon Aquarium Fish Tank (19.33 x 9.65 x 0.16in) - Fluval 12694 Plant and Shrimp Stratum for Freshwater Fish Tanks, 8.8 lbs. – Aquarium Substrate for Strong Plant Growth, Supports Neutral to Slightly Acidic pH --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/367660585-hygger-auto-on-off-led-aquarium-light-full-spectrum-fish](https://www.desertcart.vu/products/367660585-hygger-auto-on-off-led-aquarium-light-full-spectrum-fish) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
