Down Light

[MaCe 3]

i just went to a lighting shop just now.

each plc down light made in taiwan but inside part like the ballast is made in austraillia

each cost 38 bucks.

normal 4 inch plc can use max is 13 watt

normal 5 inch plc can use max is 18 watt

normal 6 inch plc can use max is 26 watt and bla bla bla.

okie ma?

cheers

then led light not bad also. each light cost abt 120 bucks

but the light need to change only after 6 to 7 years

cheers, Ching

NEVER buy a downlight that comes with ballast.

easier to change a blown bulb than to change the ballast.

$10 - $30. mine with stainless steel casing + bezel only $15.

get one without ballast - just screw in a energy saving bulb.

Mace ...

can pm me where to buy the downlight only at $15

(the one without ballast)

thanks in advance

For a 4-RM (94sqm), i am getting 10 units of square downlight for the living room [7100 (L) x 3450 (W)] which is a rectangle shape.

Wondering if a 13 watt square downlight is sufficient or 18 watt square downlight?

Can anyone advice?

Thanks.

1. 13 or 18 w is no good enought. PLC has "disfussor" so light emits to cover a limit round-area. I used all "white light".

2. Use those 2 x 13 watt = 26watt PLC. My 5-rm pt blk's hall fitted with 4+2+3 = 9 such with 3 switches. Folyer=1 such + 1 switch.

3. Dinning area with 6 such, 3 switches.

4. Study area with 6 such, 2 switches.

5. Son's rm, 4 such, 2 switches.

6. Daughter's rm, 4 such, 2 switches.

7. Master's rm, 6 such, 3 switches.

You can buy DL from Choo Chiang - they always have promo for them. Between $10 - $18 i think.

13W it enough, but again depend on hw bright u expecting.

Near missed to reply. Never too bright. The key is to install "a few" switches for a room, or a particular area. So one can control.

My precious condo applied the same concept.

Note: Nice to install "warm light" for romantic/soft ambience, but no good for reading.
