can anyone advise me on the following:
1. must each downlight be connected to a driver ?
2. if either downlight or driver rosak, can i replace using any other different brands of downlight/driver?
3. how does a dimmable downlight works? what are the additional installation required?
4. there is one lighting shop in puchong selling downlights which we can change from yellow light to white light & vice versa using remote control. can also control the brightness/dimmable.
has anyone used this type of downlights before? any comments?
thks a lot
1. Yes, unless there's huge driver that can drive multiple downlight. Not sure if this exist, but not difficult to engineer.
Cons? if that driver dies, so as the rest of the LED that are connected to it
2. Never tried before but it's based on the watts/power rating. If it matches, what brand also can fit.
3. Not all LED can be dimmable. These are digital lights, requiring 0.7V to power up. Some dimmable LED actually have high pulse rate (PWM) that our eyes cannot detect. Low PWM low brightness, High PWN (near DC) high brightness
4. I'm using that. Its actually different LED colors inside the housing. More expensive LED have multicolor spectrum depending on the voltage/current applied.
