Review on Hygger Spectrum Extendable Controller Freshwater by Crystal Robinson

Advantages: These lights are bright. Like a bright sun. For example, I have (2) 14w 18-24 inch headlights and they light up my 120 gallon deep tank like it's nothing. It's shockingly bright. And the price is just unbelievable. Bad: The timer function is insane. When you use it, the light never turns off. They simply switch to their darkest setting at night and then return to their brightest setting during the day. Another option is to use an external timer, but it will then revert to the brightest setting (bright as the sun's surface) each morning. If you prefer a dimmer setting, you have to do it manually every day. If you want to use a night light (Blue/Red only) you will need to manually change it to this setting. Solution: Buy a bottom screw dimmer and some plug adapters and you can adjust the brightness setting and it stays that way. via an external timer. If you want to get creative, plug everything into a smart socket and use Alexa to program the time you want, and she can also turn the lights on and off at will with a voice command. https://www.amazon.com/dp/B07MQ9BZCV /ref=cm_sw_r_cp_apa_i_xq6fFbEJA783Qhttps://www.amazon.com/dp/B07F33H26V/ref=cm_sw_r_cp_apa_i_ir6fFbQA26YB1https://www.amazon.com/dp/B07GYL5Q7F/ref=cm_sw_r_cp_apa_i_WVYF1bXdvYF1
