Frequently Asked Questions

How do I convert old watt values to LED watt?

Divide the old incandescent watt value by approximately 8-10 to get the equivalent LED wattage. A 60W incandescent bulb is replaced by a 6-8W LED with the same brightness (about 800 lumens).

What is the difference between watts and lumens?

Watts measure energy consumption, lumens measure actual brightness. For LED shopping, focus on lumens: 400 lm for accent lighting, 800 lm for general room lighting, 1,500+ lm for bright task areas.

What is the LED Watt Calculator?

The LED watt calculator helps when switching from conventional bulbs to LEDs. It shows the equivalent LED wattage and the annual cost saving.

How does the LED Watt Calculator work?

Enter the wattage of your current bulb. The calculator determines the equivalent LED wattage (approx. 1/7 of the bulb wattage) and computes the annual electricity saving at typical usage.

Key Data and Facts

Conversion: 60 W bulb approx. 8 W LED. 100 W approx. 14 W LED. LED lifespan: 15,000-50,000 hours. Saving: approx. 85% compared to incandescent bulbs.
