Learn everything you need to know quickly:
- Know the difference between Lumen and Luminous Flux
- Calculate the light effect parameters
- Pay more attention to this parameter of light efficiency
When you purchase the gobo lights, it need to know the power, lumen, luminous flux. As different item with different power and the luminous flux.
How to calculate the light effect parameters of gobo projector?
Luminous Efficiency = The power of total luminous flux.
That means if the photosynthetic efficiency is more high , the electric energy of gobo light transform optical energy more strong. It will be more energy-saving if with high of photosynthetic efficiency in the brightness.
Some of gobo lights suppliers only advertise the high power of gobo light. However, if the luminous efficiency is relatively low, then the brightness is relatively small,That is why we emphasize different manufactures with different brightness of the same power. Therefore, The customers should pay more attention to this parameter of light efficiency when purchasing the gobo projector. When high power, high light efficiency, brightness is great.
Take our company as an example, the luminous efficiency of our LED lamp is 100-110lm/W, and the light efficiency of metal lamp is relatively low, only 50-90lm/W.
For example :
- 20W LED lamp light efficiency = Total luminous flux power = 2000lm/20W = 100lm/W
- 1200W metal lamp light efficiency = Total luminous flux power = 110000lm/1200W = 91.7lm/W
