LED Savings Calculator (Philippines)

How much will you save on your Meralco bill by switching to LED lights, and how fast will they pay for themselves?

Number of lights

Hours per day

Old bulb/tube watts (W)

LED watts (W)

Tip: a T8 36W fluorescent tube uses about 36–40W with ballast and can be replaced by an 18W LED tube. A 60W incandescent bulb can be replaced by an 8–9W LED bulb.

Other monthly usage (without these lights) (kWh, use 200 if unsure) Cost of LED replacement (₱, optional)

Monthly savings with LED

Bills before and after are estimated with Meralco's September 2026 residential rates, including the distribution bracket. Dropping to a lower bracket can increase your savings.

How it works

Lighting energy (kWh) = number of lights × watts × hours per day × 30 ÷ 1,000. We add it to your other usage and estimate your bill before and after switching, so a drop to a lower distribution bracket is counted too.

Typical replacements

Old light	Approx. watts	LED option
T8 fluorescent tube (4 ft)	36–40W	LED tube 16–18W
Circline fluorescent	32W	LED ceiling light 15–18W
Incandescent bulb	60W	LED bulb 8–9W
