I decide to go for branded LED downlight. But, i heard one contractor said that philips LED will be more difficult to install. Is it true? He advised me to go for Megaman or OSRAM. Both also from Germany. I believe all of them are same quality standard, right? or do you have any thoughts on this?

For Megaman 5 inch 12W, I can get better deal at RM16.90/unit with 2 years warranty. Have not negotiated yet. I was thinking to get lower rate with bulk purchase 20-30pcs.
For Philips with same size & power output the  best deal I can find is around RM17-18/unit with 1 year warranty only. Another deal is RM22/unit with 2 years warranty.

Should I go for Megaman? Anyone using this brand b4?

Question: Which one is better? and why?
1. Megaman beam angle: 120°
2. Philips beam angle: 110°

I have seen a demo by one of the PHILIPS Professional Partner in my condo demo.
As per normal our corridors were using those generic China LED DL D150 18W (rated 1500lm). They showed up with an equivalent D150 size DL but running only 12W (rated 1300lm). Hence it is a direct fit.
The generic China 18W when measured using a light meter only got about 70-80lx while the PHILIPS 12W under same condition got 110-120lx.
They then bring up another unit same sized but running at 9W (rated 950lm) and was measured at 65-75lx. Now JMB deciding to go for 9W or 12W model. Running 12H per day, every 1W saved is equivalent to RM 2.40/year. The unit offered is with 5-Yr warranty.

China 18W got about 70-80lx, are u talking about beam angle?

For this "Running 12H per day, every 1W saved is equivalent to RM 2.40/year", where can we get proof on this?

They demo using a digital light meter as brightness of a lamp is not measured by the eyes. The light meter will measure the brightness, the higher the number the brighter it is.

The savings RM 2.40/Year you can download the respective tariff table from TNB and calculate it.

I try to calculate but could not get RM2.40 per year.

Every 1W running on 12hrs daily will save Rm2.40, but I only can get RM0.94

1W x 12 hrs x 360 days = 4320W (4.32kWh)

For the first 200 kWh (1 – 200 kWh) per month, the rate is 21.80

Estimated bill: 4.32 * 21.8/100 = RM0.94

so it should be RM0.94, right?

Our condo is on 0.509KWH rate + ICPT 0.0037 = 0.546KWH
Corridor lights are switched on 12H/day = 4.38KW

For own house use, the average usage is 4Hrs/day, therefore only RM 0.80/year for every 1W. However, the quality if the light you get from PHILIPS will be much more better especially they are rated at CRI80. Generic ones, they usually do not quote their CRI ratings, so it could CRI70 or worse only.

The demo also mentioned that PHILIPS utilizes L70B50 meaning during the warranty lifespan the light output cannot be lower than 70% from the 1st day installed. If lower it is considered warranty claim. Cannot really remember the B50 ratings already

any LED bulb or downlight with high CRI spec?
*
I am using PHILIPS GEN9 MyCARE Bulbs with CRI90.

There also another downlight from PHILIPS that I use is CRI90 also but forgot the model. Not easy to find. For 6" I paid something like RM90. But light quality is really good.

This 1? price seems acceptable

3500k is very yellowish?

No, not this shape series. It looks like conventional round bulb type. Either 3000K or 6500K is a matter of preference.

High CRI light very hard to find locally.... at most also 80+

Taobao got more choices when it comes to 90+ CRI

China branded specifications, I will take it with a pinch a salt. Many over promised, under deliver.

But how do you actually know? All the branded stuffs also made in China nowadays. In fact many lighting supplier here in Msia source their lights direct from China also except maybe certain high end brands

For example brand like Philips, I can buy the same model that is available here in Taobao for cheaper, especially if you buy in bulk. If you dont trust 3rd party sellers you can always buy from their official stores, same as Lazada / Shopee only. And there's even more choices of models available there

Branded Made in China and China Branded are very different. If you traced back my earlier post, I have seen FSL LED T8 Tube 18W being outclassed by PHILIPS 10.5W tube. Lux level in fact the FSL 18W even loses out to PHILIPS 10.5W. My condo just changed the 6" Downlight from China Branded 18W to PHILIPS 12W. Again the lux level is higher. I saw the demo before.

Buying from China is no big issue, just ensure the voltage range is 220-240VAC and not 200-220VAC.
