there are 3 types of control way
1, remotor : called "Shannon" , now there is a S16 (reef , fish , plant) version which is 30Watt.
2, controller : called "Turning", RS90, T75, T50, all are stop update.
3, Phone/WiFi: called" Herzt", RL60,RL90,RL180 (compact design) , H75,H50 (no fan, best cover the tank)
with more and more functions (Lunar, slow accalamation, simulate the sunshine of different region), it is impossible to set only by remotor and controller. so phone/WiFi is the best.
The wifi module (internal electric boards) is Tuya. we develop the function. the advantage is Tuya deploys a number of local servers to ensure the appropriate speed when run rich functionality. This is one of the most beloved features of the PopBloom WiFi light.
The noise is really annoying considering several fans spinning on one tank, also it is impossible that each light has same fan-noise ( I mean, Sometimes you think the left side is the loudest, no matter how much you swap lights) :).
Almost every brand of light with a fan has been complained about noise (redsea, echotech ). As the testing, RL90 is better 11% (front) compare with Redsea 90. RL180 is 14% compare with Redsea 160 , same as echotech.
