Comparative research
Our internship Dion of Eindhoven University has already researched the diversity of LED headlamps. This was largely theory and a little practice experience. Now we have done a new test in collaboration with TU Eindhoven, which makes it possible to compare with other widely sold leds of competition.
We think it's important to do a fair and transparent research as possible, so we chose to do this with a reflector headlamp. In case of these headlights, the likelihood of a poor light image is larger than that with a lens where the light is better projected on the road surface.
Which LEDs have we tested:
- Our neat XTR LED with Philips Luxeon Z ES chips
- A commonly sold led from any competitor with Luxeon Z ES chips
- A product with CSP LED Chips, these are led chips from Korea which appear like 2 drops of water on the Z ES chips but perform differently, these are also often sold as Z ES led chips on various Chinese webshops.
Heat production
We have 3 measurement moments, 1 after 30 sec, 1 after 15 minutes and 1 after 30 minutes. We measured with an ambient temperature of 27.3 degrees. Yes, it's hot in the summer!
Light beam
And then actually the most important aspect of good lighting, the light beam or the light image. Where is the light going and what does the spread of the light do with the final light output? We have used a Highlander headlight because this headlight with halogen also has a good light image. This way we can make a better and fair comparison.
Disclaimer: Although our test has been performed very accurately, there is always a chance that there is a small deviation, because the light image is highly dependent on the headlight quality. Recent US research shows that not all car manufacturers produce a great headlight. Therefore, no rights can be derived from the above research.
