Great light. Set up was easy. Timer works great. I really like the blue light and the moonlight effect. Some people had commented that setting the times was hard. It was straight forward and easy. Very happy with this light. Havent tested par so not sure if it would work for corals, but works great for lighting the tank.

So this is a great light as far as functionality. I allows you to set a timer, the I intensity of the LED on different channels and even has a sunrise and sunset option. However, if you loose power, the time is reset. In my recent experience, the other configurations were not lost. Not sure why time needs reset but the rest of my configuration was good.This has great configuration options. It’s pretty customizable for the price. Make sure you read the short instructions ahead of time so you understand the codes and the button presses.The white LED is not exactly a high white. The white alone without the blue is really ugly. I always have the blue on with the white. I actually lower the white intensity a little to about 50% to give the tank a little more blue throughout the day. I did notice the white channel has some green spectrum mixed in which might cause this.The white and blue are on different channels so you can have a timer for the white and a separate timer for the blue with different intensities.My favorite part is the sun up and sun down uptown. There is a setting to turn on the lights fully, or use the sunrise-sunset option. Sunrise and sunset each are hardest to 15 minutes.My setup turns on white at 50% intensity and blue at 100% intensity late morning. The white fades off early evening for an all blue moonlight and then a couple hours later, the blue fades off to night.I would buy again at this price. I would also request the manufacturer to put brighter white LEDs for a better white color.

I am really enjoying this light on my 100 gallon saltwater aquarium. It is about 1/3 the price of the name-brand unit it replaced and works every bit as well. And it is bright. Very bright. I have a fish-only tank and don't need to turn it up past 20%. The controls are easy and intuitive, and I like the settings for day and night lights. Thumbs up!

The reaction of my corals that I started again was incredible, they love the light and automatically opened up.

Bought this light because it was cheap and they said it could support lps and soft corals. It does not my corals look sick under this light it’s no where near strong enough it’s does not provide good par it is bright might be good for a freshwater planted tank but not corals I have the 24 watt 24inch to 30inch on a jbj 45 gallon would not recommend

bulletproof light, been sprayed, soaked, dunked, etc with saltwater and still going strong. got one led that is finally starting to go out, but just dont submerge it in saltwater and you wont have that issue.

I've had this product a week. The lighting is good, but the timer is difficult to program. 5-7 days and I haven't been able to figure out this time
