1) Check at your DB box MCB. Normally MCB for light is 10A or 15A. For 10A = 2400W. Do your calculation that your bulb add in total.

2) Your MCB trip.

PLC lamps can be dim as well. but u need the correct ballast

there are newer energy saving lamps which let u dim

Price of lighting in TXX TXX puchong increase. (Inflation?)
Find that the price there is no longer competitive anymore.

Last month went to survey downlight and get quoted RM18 for ballast 6 inch downlight, this month went back and the price already increase 16-20%

Even the uncle customer stand beside ask the sales person the same question "why is the price from last month is different than this month?"

But then there are some items (which they buy in bulk) are still cheaper than other lighting shop. just try your luck!

This is make sense.
China labour cost also increase significantly. Perhaps, China made product will not as as cheap as before.
Raw material cost also in increase trend.

My electrician suggested that I use normal fluorescent light (warm yellow) to replace the T5 lights.

According to him, fluorescent light has longer lifespan than T5.
Did anyone here use normal fluorescent light to replace T5?

anybody here using Led Downlight example 12 W 4"/6" type?
How much is the current price including driver?

My kitchen area was fitted with 10x GE energy saver, within 5months, 4bulb blew off. quality speaks for it self. Now i switched to philips, let's c how long they lasts.

Philip also is a crap. My early home using, is all philip. Now switch to hitachi. Running 2yrs average or 8khr before burn. It is between the spec as it claim.

If it blow off between each other continue, maybe cause by the high voltage. Sometime incoming is 250v.

Your "normal fluorescent light" you meant is T8?

Lee Yung, yes.
T8

T5 or T8 is same florescent light. T5 come with electronic ballast, and T8 can be coil or electronic ballast. Performance t5 is better. Don't get China brand, need to get reputable brand.

Nowadays T5 is the preferred flourescent light as it isthe newer and smaller model, but lighting wise T8 being bigger is arguably brighter.

But T8 brightness reduce after sometime.

Big does not mean bright. T5 is much brighter.

Never heard bout this wor..

My working place using alot of T8 light. Definitily can see the brightness reduce after a year. The reduce brightness make you feel dull.

Real practical example, mad valley parking used to be t8, they change to t5, and during transition can see the difference, and now the parking is so much brighter. My mom house I replace the old t8 to t5, brightness is so much much difference.

Dear Expert/Sifu,

I m not sure the qty of my downlight surrounding my Lbox(light through) is sufficient or not, attached 2 picture here for advise.

I m so confusing.... and anyone know the cost to install dimmer?

Thanks in advance.

Dimmer you have two option LED or halogen type. Led will be more expensive, halogen will be cheaper, but running cost is higher. Another forumer mention can use Pll light with special ballast, but I have not personally seen it before.

My house use t5 in the light box and within the light box area I put down light.
