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?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.

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
