Lumen Output – Halogen vs. LED

You have probably heard of the many benefits by switching to LED lighting. In this blog post I will be talking about lumen output and in doing so, I will compare Halogen and LED on the basis of lumen output.

In our example, I am comparing a Halogen PAR30 and an LED PAR30. See the table below for the technical details:

Halogen

LED

Shape

PAR30 Longneck

PAR30 Longneck

Energy Use

75w

16.3w

Lumen Output

980

800

Beam Spread

25

23

Application

6” ceiling can

Foot-candles

89

104

Foot

I’d like to call your attention to the lumen output and the foot-candle measurement in the above table. The Halogen lamp has an output of 980 lumens while only producing 89 fc and the LED lamp has an output of 800 lumens and is producing 104 fc. Note: Each light was measured in the same ceiling can with the same ambient lighting.

LED Foot-candlesSo how are 800 lumens outperforming 980 lumens? A true LED lighting expert will tell you it’s the difference between initial lumens and delivered lumens. Initial lumens are the quantity of light output measured after the first 100 hours of operation using controlled system characteristics. What? Basically, initial lumens is the light output of the lamp or luminaire before any light loss factors are considered. Delivered lumens is the light output of the lamp or luminaire including factors of light loss, optics, heat, etc..

So why is this important when you switch to LED lighting? It’s simple really. If you are happy with your light levels and think you can switch to LED based on similar lumen output you are likely in for a very BRIGHT surprise! I would recommend that you consult with your LED lighting experts at LED Source before you make the switch. This will ensure you get the right amount of light for your application, and who knows, you might be even able to reduce the number of lamps or fixtures that were previously used. Another bonus point for LED lighting!!
