Yes..
Usually there is 2 type of led lighting..
1 is with external led driver this 1 is good and can be repalce easily. Usually can find the driver easily anywhere.
2 is build in driver, can be good and bad.. good thing is 1 pcs hardware bad is when spolit usually is throw away. Some still can change back to the same brand n model driver.
So either u buy additional driver or light to keep...
For my home i got 35 downlight so i brought 40pcs if got spolit i can replace directly. The 1 i brought is philip downlight which is 1 pcs hardware so have to buy some and keep cuz they can eol the products anytime,
Another thing is to take note that they always market LED as below
Led last longer 5-10 years - yes it can last very long but as time goes buy the brightness will decrease, led can last very long but not the PCB or the led driver so if u got a lousy brand driver u will end up spending more money to replace.
Temperature is lower normal bulb- yes front surface is nt hot... try touching the back of the led.. can be very very hot tats y some have large heat sink to dissipate the heats.
Color temperature - especially warmwhite the color can run abit u will see some will be more or less yellowis. So i advise buy same batch production to lessen the color difference.
hello sorry because Im not familiar with lights. So as spare, I should buy LED DRIVER along with the full set of lights?
