Good Day To You All.
I am looking for advice with regards to LED’s.
But 1st I better let you know what it is I am trying to do.
More and more new cars on the market use LED based rear lights, for side lights, brake lights, ect.
My car is 20years old now, so still uses incandescent light bulbs.
I would like to remove the old incandescent light bulbs and replace them with LED’s.
The problem I have is that LED brightness is given in lux, mcd, lumens, not in watts
From my understanding lumens is the right way of finding out the brightness of a LED or Bulb, ect.
Most of the web sites I have looked at so far list the LED brightness in mcd and not in lumens.
All the bulbs in the rear lights of my car are clear, as the lens (cover) of the lights is frosted with the colour needed, So I will only need wight LED's.
I know a lot of the users here don’t like giving out any advice when it comes to Main’s Power related or Automotive Related questions.
I am not going to be trying to change the front main lights to LEDs, but they are being up graded to HID lights.
I am just trying to feel like I am bringing my poor old car into the new age.
So my main question here is: Are there any charts or conversions so that I can find out what brightness led would be compaible of replacing say a 5watt & 21watt incandescent light bulbs?
Thanks for your time.
Best Regards.
