Convert lumens to watt

Lumen is the unit of luminous flux and indicates the total amount of light emitted by the light source. Wattage indicates the amount of energy consumption of a lamp. As lights are becoming more and more energy-efficient, the wattage at the number of lumens become lower and lower. For example, to replace an incandescent lamp with LED , the amount of lumens must be compared. With the table below you can easily compare watt with lumen.

Type of bulb 200-300
Incandescent 25-30 Watt 40 Watt 60 Watt 75 Watt 120 Watt 150-250 Watt
Halogen 18-25 Watt 35 Watt 50 Watt 65 Watt 100 Watt 125 Watt
CFL 5-6 Watt 8 Watt 11 Watt 15 Watt 20 Watt 20-33 Watt
LED 2-4 Watt 3-5 Watt 5-7 Watt 8-10 Watt 10-13 Watt 13-20 Watt

Color temperature

To determine which type of lamp you need, it is also important to look at the color temperature. The color temperature indicates the color of the light coming from the lamp and is indicated in Kelvin. The lower the number of degrees in Kelvin the warmer the light color. The most common color temperatures (Kelvin) are:

  • 2700K = Very warm white light. Provides a relaxed and intimate atmosphere (home environments)
  • 3000K = Warm white light. Not too hot and intense. Pleasant to the eyes (office environments)
  • 4000K = Cool white light. Sharp white light. Ideal for work environments (warehouses etc.)
  • 6500K = Daylight. Similar to daylight. Applicable in areas where everything must be clearly visible (company halls, factories)
