I don't know how my contractor calculated (5). Although he quoted me $45 per wiring point, I end up 2/3 of my downlights need wiring, so end up a hefty big bill close to $2 k for the wiring alone May I kenna chop but he mentioned that he will install wiring pipe on the ceiling concrete and run wires inside them. My item (6) is the same as yours but mine is square LED so requires more skills. I didn't ask for quote for manhole but maybe I should as I think I need to change the LED drivers in future.

I agree. If the house doesn't come with false ceiling, better to leave it as it is. Cheaper and easier maintenance for lighting and fans, plus higher ceiling height for loft effect.

I was told by a lighting vendor that if there is a chance of rain splashes, then it is better to avoid LED lights as humidity reduces the lifespan of LED lights. My T5 outdoors are CFL.

I think outdoor wise T5 using CFL is better.

Mine was less than $40 RM. Location is Johor.

T5 is very bright. Purchase price is very good compared to LED. So I think outdoor use like car-porch if you don't need to switch on for several hours is very good value for money. Also less worry if they are stolen.

I estimate a factor of 1.5 for LED light. E.g. I equate 12 W LED to 18 W CFL.

This is my first floor LED light along the corridor:

I selected LED lights with temperature 4100k (similar to rice grain color), as lower temperature is too yellowish and higher temperature is too glaring for me.

That photo was taken in the afternoon.

Two LED downlights of 12 W each is just sufficient for a small bedroom. For master room that is larger, it is advisable to install 4 downlights of 12 W. You can adjust the number of downlights according to the layout of your room and the power of the LED. The lower the power, the more you need to install, but the more uniform lighting you will get and the better the effect. The downside is the huge cost for lighting renovation and higher chance of cataract for over brightness.

For my case, I installed four 12 W downlights with one at each corner for all my small bedrooms. They are connected to 2 switches, with each switch controlling 2 downlights. I installed five 12 W downlights for my master room. Below is a photo for my dry kitchen, which is about the size of a small bedroom, with four 12 W downlights. You can judge yourself whether it is sufficiently bright.

That is all I have. My whole house interior is LED, even the toilets (actually not advisable since humidity is high but I just want to standardise 12 W LED so that I just need to stock up one type of spare LED lights):

The living room lights are different as it is not plaster ceiling


The staircase lighting is also LED

Yes, every light is LED, even for the store room light. I just wanted to try LED

Not sure about shadow as I din really look out for them. My lights are spaced quite far away from the fans. I can check them out next time.

Staircase LED light - $250 RM
Ceiling light (with four LED lightbulbs) - $550 RM x 2 sets

I used 6 W (4100 K) per bulb x 4 bulbs per ceiling lighting, so total is 24 W. The two ceiling lights are sufficient for the living room and I like them very much. There are many designs that can accommodate more or less bulbs. I threw away the boxes already so I'm not sure of the brand. Have fun chosing.

Yes, quite cool. I can hold e LED light bulb at e shop despite being switched on for 1 he.
