LED Wattage Guide: Replacing Halogen and Incandescent Bulbs
Switching from halogen or incandescent bulbs to LED is one of the most effective ways to reduce your energy consumption at home. The key is knowing which LED wattage gives you the same brightness as your existing bulb.
Understanding Lumens vs Watts
Traditional bulbs were measured by watts, which indicates power consumption rather than brightness. LED bulbs use far less power, so the wattage comparison is not like for like. Instead, brightness is measured in lumens (lm).
Halogen to LED Replacement Guide
| Halogen Wattage | Equivalent LED Wattage | Approximate Lumens |
|---|---|---|
| 20W | 2 to 3W | 200 lm |
| 35W | 4 to 5W | 350 lm |
| 50W | 5 to 7W | 500 lm |
| 75W | 8 to 10W | 750 lm |
| 100W | 12 to 15W | 1000 lm |
Incandescent to LED Replacement Guide
| Incandescent Wattage | Equivalent LED Wattage | Approximate Lumens |
|---|---|---|
| 25W | 2 to 3W | 250 lm |
| 40W | 4 to 5W | 470 lm |
| 60W | 7 to 9W | 800 lm |
| 75W | 10 to 12W | 1050 lm |
| 100W | 13 to 15W | 1521 lm |
Tips for Getting the Right Brightness
- If you want a brighter room, choose a higher lumen output
- For a cosy, ambient feel, choose a lower lumen output with a warm colour temperature (2700K or below)
- Always check the lumen output listed on the product page rather than relying on wattage alone
