HappyBird Lighting Programmable Sunrise Sunset Dimming Timer - Slowly Dims On & Off - Works on Any LED Light - Auto On and Off - Provides Accurate Timing – Comes with Built-in Battery Backup

This product works well and the seller is responsive.

I am super happy I got this in addition to the light fixture it goes with. Having the auto light feature is a lifesaver for me and my bird! Love this so much. Great quality and easy to use!

Its great and the sunrise/sunset is so helpful but you need to reset the timer about once a month because it runs a bit too fast and will start turning on too early

I like the ability to adjust the on off times on this unit, you have to watch the main time function gos out of sync and needs to be adjusted now and then.

This timer,works great on my AquariumTurning the lights on and off.At any programmed time.It has a fade in and outWhich gives my fish time adapt.Very nice product so far.Its bin a month...Very satisfied.

This item requires a power supply. When I ordered there was no reference to the fact that a power supply was not included only that it only worked with low voltage dc lighting. Also the power input and output cords are very short(less than 4 inches each) so for practical reasons you need a power cord extension for a light. I didn’t know what kind of star rating to give as I haven’t had a chance to use this as I am waiting on a power supply and cord extension.

got this for my aquarium. programming was a breeze, had it for months now, worked flawlessly.

Works great. Makes remote chickening so much easier.
