Delighted with this aquarium light! My fish colors are on full display. All the light options are included, and I can put light color, brightness and on/off on a timer. Just use the 24 hour clock, not the 12 hour one, and you're good to go.
I have 3 of these lights and I love them. They turn on at 7 am and turn off at 7 pm. They are great for my plants also.
I'm very pleased with the SR-666. It has worked very well so far in my planted aquarium, and I like the programming features. The timer was a little confusing at first, but it was fine after I got used to it. Overall, very happy with this light and highly recommend it.
See the attached photos of two of my planted tanks running these lights. You get a lot for the money. One has been running over a year with no issues.
This is fantastic and works exactly how it should. Has many options of color density and light strength we use it on our 75 gallon tank and depending on the plants we have in there or things we change up this light allows us to use one light for multiple reasons and we love it!
