Product Features
- 2 Light Modes are Available
This LED fish tank light provides 2 modes to light up fish:
1. Default mode (24 /7 natural mode)
Gradient Orange light (sunrise) from 6 am to 8 am;
Gradient White light from 8 am to 6 pm;
Gradient Blue light (moonlight) from 6 pm to 10:50 pm;
The LED tank lights are off in other periods.
In this natural mode, the light slowly wakes up by emitting dim orange light at dawn, bright full spectrum light during the day, and blue light at night.
Once it is set up, the light will automatically turn on and off at the same time every day. The light color and intensity are fixed. The indicator light on the top of the hour points out the current time range.
You can press the 24/7 button once to choose 8:00, and the indicator light is red.
Please note that the 6-time points on the controller are used as a reference for the first running time setting. In other words, the overall default period can be delayed or advanced.

- New upgrade
This LED fish tank light is waterproof and easy to clean and wipe, so there is no need to worry, even if it falls into the water briefly. With the separable adapter, there is no need to replace the whole light even if it is damaged. The extendable bending bracket can be adjusted in length and can be applied to various freshwater tanks. Thicken aluminum increases heat dissipation efficiency.
- High-quality LED aquarium light
The fish light is soft, and the color rendering index is close to natural light, protecting eyes and fish, to refuse the discomfort caused by stroboscopic fish and viewers. Using high-quality 2835 + 5050 model lamp beads, it has a long service life of at least 50,000 hours.
- Adjustable timer & brightness
Lighting time can be programmed to 6 H, 10 H, and 12 H. Lighting mode can be adjusted to 9 stages of brightness (10% – 25% – 50% – 75% – 100% – 75% – 50% – 25% – 10%).

Wanted the Fluval 3.0 but couldn’t justify its lofty price tag…$200 – 300. This light is a great alternative. I use the 24 hour cycle mode and my plants and fish both seem too like it. Although it doesn’t have an app to control settings ect, if you just need a plant light that can penetrate down to the substrate than this light cannot be overlooked at the price of $60.
The finnex light I had for my plants died unexpectedly. I was looking for a quick replacement, I don’t have any extremely demanding plants and so far it seems fine. I’m using the 24/7 option. I have a crazy schedule and feel like this option gives my fish atleast a little bit of normal day cycle & easier transitions. It unfortunately did arrive damaged, hygger offered a small credit for the damage or a return. Fits my 55 gallon well. I like the low profile. I’ll have to see how plants fair long term.
Absolutely love this light. It’s so easy to use and it’s bright and beautiful in color. Mine, for some reason shorted out about five months in, but I contacted the company and spoke with Luna and they had a new one sent to me within two days of me sending the email. Great customer service, great product. Very happy and highly recommend this product!!
Compared many led systems to me the Hygger units are the best!!!! I will even compare them to the Fynex plant series which is a more expensive price point. Customer for life,I would love to evaluate new systems for the company,hint lol
This light is the best I had so far! I love the 24 7 automatic. Light slowly comes on at 7:30 am & in moonlight mode at 7 pm, & off at 10pm.My fish & plants are thriving.
