Where the best place to get LED strip? I actually need 2 x 110cm only. Jalan Pasar?

Hi Strip you can get from anywhere, make sure they supply you brighter ones.
where you stay, i can recommend one of my dealer or my kaki shop near your place

make sure you buy a good driver, nothing less than 80 buck for less than 100w
usually driver gives you problem , strip not really

Hi, good idea, don't dim your LED even it is dimmable
anything pass thru a dimmer, the power factor drops, even you max out dimmer, you can't get 100% brightness out of the LED
unless your LED is too bright and you have dim, then no choice.

Unfortunately my dimmer is embedded into the original house. It will cost money to rip out and install another set of wiring and switches.

looks like you going to spend money anyway.

one normal switch to replace the dimmer is about RM3 , labour maybe about 20 buck
or you change the dimmer to a more efficient dimmer, estimate about RM300

so change to a normal switch still cheaper way , you don't need a set of new wiring

The wiring seems different. But thanks, I will consult my electrician and make a cost comparison.

hi, i am pretty sure is the same wiring , you just need to change from the dimmer switch to normal switch
and i am pretty sure you LED will be brighter.

3 possible way to solve this:

1. maybe your dimmer not compatible with the LED light

2. voltage drop - i am assuming you loop the LED in series, is like switch to 1 to 2 to 3 to 4 back to switch
    what you should do is loop parallel , switch to 1 and back , switch to 2 and back etc  or use bigger cable if you do series

3. don't loop too many units together, like 8 unit with 2 dimmer switches instead one 1

if is the driver problem, then the unit is not suitable for dimming. then don't dim ...
i think no. 2 is the most common problem, even with Aztech LED

dear sifu, my electrician told me that in order to do the point (20 above, he would need to re-wire the connection as currently two LED lights are wired to one switch. Is it true? Tx

1. maybe your dimmer not compatible with the LED light
>>> i think you change to normal switch , cannot dim will be a easier solve
>> if 2 LED to a switch, dimmer shouldn't have any problem, so i guess is not dimmer problem


2. voltage drop - i am assuming you loop the LED in series, is like switch to 1 to 2 to 3 to 4 back to switch
what you should do is loop parallel , switch to 1 and back , switch to 2 and back etc or use bigger cable if you do series
>>> yes, you need to spend a lot, i guess you better live with it or don't dim at all

3. don't loop too many units together, like 8 unit with 2 dimmer switches instead one 1
>>> same as above

sorry, best to save money is not to dim, unless you want to spend some money there
also if dim the Power factor PF will drop, mean the brightness will drop even you max out the dimmer
depends on the dimmer and driver, it could be as much as 15% - 20%

driver = transformer , is converting energy from AC to DC , same function
Gama, no comment , never spec there things before

Yeah, following the advice of the bros here I junk my dimmers that come with the house. Brightness, durability and energy saving are more important to me.

well, doesn't mean more wattage give you more brightness , for example

X brand old model 10w give you 400lm
X brand new model 7w give you 550lm
so which is better ?

depends what specification they give you, for current bulb technology is > 80lm per what and usually is 270 degree, rather than 180 degree angle.

so if you have about 720lm for 8w, current is about RM 40++ per bulb retail with 1 year warranty. your price i assume is less than 550lm, 2012 technology
