If you’re planning on purchasing new work lamps, you ought to consider the light output. Your lamp must provide you with ample light.

The number behind the light output, what does it mean? What’s the point if you have to struggle in the dark?

The operation and theoretical value of the light output have been added to our LED work light’s specifications. What do these values depict, and what are the differences they state?

Let’s find out.

The Value Of A Single LED

The maximum number of lumens each individual LED can produce in light. It is referred to as the theoretical light output.

The external factors that influence the light output are not considered when calculating the value of theoretical light output. Focus on the electronics and lens to understand the effectiveness of heat produced.

Light output cannot be achieved through theoretical values in practice. However, reading the value of the practical light output can help you find out the amount of light a work lamp produces in a stable environment.

How To Measure The Light Output

Measuring the light output as soon as the work lamp is switched on would give you a slightly higher value. This is because the lamp has not been heated up yet. So this value cannot be considered accurate.

Measuring the light output after the work lamp has been switched on for approximately two hours would be realistic. It would be stabilized by then.

Finding The Values Is Similar To An Autotest

The difference between the output of operational light and theoretical value can be kept in comparison to a new car’s test. This test indicates that the vehicle’s consumption is 1 in 25.

But the fact that it is not mentioned where the test drive happened. It has driven around 50 km/h and special tires.

The value achieved in theory can be entirely contradictory to practical value. Thus, relying on the light output based on the practice tests is more accurate.

It applies to these work lights as well. If you want to see the realistic light output, make sure to check the practical or operational lumen value mentioned in the specifications.

What To Assume If Only A Single Value Mentioned

In case your lamp does not specify whether you are dealing with theoretical or operational values. It can be concluded that the value mentioned is more likely to be theoretical.

Manufacturers presumably mention the value of the theoretical light output as it is higher than the value of operational light output. It tricks you into assuming that the lamp emits much more light than it actually does.

Output Of Light Is Comparatively Lower When In Operation

New Vision lights produce top-quality work lights. Plenty of attention is paid to the design and production of the electronics and the dissipation of heat in the lamp.

The value of operational light output is on average 35% lower than the theoretical light output in an NV light.

Compared to NV’s light lamps, cheap light lamps pay very little attention to electronics and heat dissipation. Therefore the difference between the theoretical light output and operational light output is vast.

You can divide the number of lumens stated in the cheap light works by two to determine the operational light output.

Other Factors To Consider When Purchasing A Work Lamp

Apart from this, the light output other factors that need to be considered when buying work lights are:

• The electromagnetic compatibility and your work lamp’s Ingress Protection Rating (IP).
• Maintenance and resistance of the lamp.
• The external environment and the location where your lamp is being fixed.
• And considering whether your work lamp is energy conservative is essential.
