hi all,

may i know in term of tahan lama, comparing LED with normal downlight is there big difference?

currently calculating cost of installing led vs normal downlight, i only know LED save electricity but how about in long term for eg. changing bulb will i be able to save more in long term?

Guys, if I were to modify my room's normal lighting point to a 4 down light points, Will the electrician charge rm50x4 =rm 200 ? If this is the case, it's too expensive.. I thought he will just need to loop the lighting points and it should be cheaper, about rm20-30 per loop? Any idea?

A lot better than those china led. If you don't mind the price.

how much per piece? this type can change the bulbs if rosak nanti?
i think i cant afford it already.

even china made also not cheap.

what is another alternative?

From the forumer here said, probably cost rm400+. The led cannot change. It come in whole set.

The alternative is use CFL.

can i replace my halogen running on 12v with these?
just change the bulb?

If your halogen is 12vdc and same kaki, should be no problem.

ok thanks for the help

at the moment, there is no guarantee for LED. how long they can last is anyone's guess. Even the Osram LED bulb, it is written 3years guarantee, but when you check the website, it says only warranty in Europe. why? Europe's current is more stable, here, variance can be big. so LED can rosak.

LED now have wide range in prices. Cheap ones may not necessary rosak faster, but the lumens drop, i.e. gets dimmer as times flies. Find out more info in the net, then u can get a clearer picture.

I see... Thanks for the info!

Hi, I would like to seek opinions from the experts here...
My ceiling height is only 100" and planning to use 4" downlight without glass..
what is the suggestive distance of each downlight?
I prefer bright environment

If you're using 4" downlights and want a bright environment, I would say at least 4-5 feet distance.

guys about MR16 LED bulbs again -

the ones i found locally all have the drivers externally. the ones i saw on eBay are all packaged into the MR16 bulb itself. any problems with that?

normally wat light u all use for bathroom?

I just would like to know if there is a wiring problem for the downlights (plastered ceiling), will it cause the energy saving bulbs lifespan to be much shorter than expected?

Hope to hear some advice. Thank you.

Wiring won't cause problem to your bulbs. Wiring problem cause your power trip and short.

Bulb problem is from quality of the bulb and the over voltage problem.

What is your bulb lifespan now?

To some people one year is short, for me one year is consider ok for bulb without ballast when install at place need to switch on and off frequent.

What bulbs are you using? With our without ballast? Without ballast energy saving bulb won't last long especially on off too frequent.

Thanks for the replies... i only found out that there is a dimmer connected to the energy saving lights. I suspect without me knowing it may cause the voltage not being stable... and causes flickering that i did not notice. That's why the light bulb goes off fast.
By the way, if i'm not mistaken the bulbs are only 2-3months old that's why it is a bit odd.

Need to remove the dimmer connection... and monitor this senario.

Thanks again.
