Recently I came across few downlights on Shopee/Lazada but do not know how to differentiate branded vs no brand LED downlights. See below for my comparison.



Philips: https://shopee.com.my/PHILIPS-MESON-59466-1...3f-a5d358846695
No brand: https://shopee.com.my/product/244022032/4781463737

The one I highlighted in green means superior than the another. Philips' lifespan is 15000 hrs which is 3x more than "no brand" but the price RM18 is almost 3x. In terms of warranty, Philips can only provide 1 year. Should I consider to go for no brand since it can provide 2 years warranty? Usually what are the coverage during warranty period?

Does 1200lm (no brand) perform better than 950lm (philips)? Will it be too bright? Will there be any difference in terms of color temperature based on same 4000K for Philips and "no brand"? Will it provide same functional lighting and atmosphere?

Philips stated that it can give 80% energy saving. Do you think "no brand" can give the same assurance?

Besides pricing, warranty, the other things to consider is easy of installation (for future replacement), please advise if "no brand" can easy to install as well.

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°

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?

How do we calculate our electricity bill? Let say I use 1x 12W LED running on 12 hours per day, how much is monthly electricity cost? Is the calculation below correct?

Total consumption: 12W x 12 hrs x 30 days = 4320W (4.32kWh)

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

So estimated bill: 4.32 * 21.8/100 = RM0.94

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?
