Lumens to LED Watts Conversion Table
Lumens to LED Watts Conversion Table reference with assumptions and boundary notes.
Reference boundary
Lighting estimate only. Actual wattage depends on fixture efficacy, driver losses, optics, temperature, and product data.
Reference table
Estimate LED wattage ranges from lumen output using typical efficacy assumptions.
| Light output (lm) | At 80 lm/W | At 100 lm/W | At 130 lm/W |
|---|---|---|---|
| 450 | 5.6 | 4.5 | 3.5 |
| 800 | 10 | 8 | 6.2 |
| 1100 | 13.8 | 11 | 8.5 |
| 1600 | 20 | 16 | 12.3 |
| 3000 | 37.5 | 30 | 23.1 |
| 5000 | 62.5 | 50 | 38.5 |
| 10000 | 125 | 100 | 76.9 |
| 20000 | 250 | 200 | 153.8 |
