did you have a chance to measure the lumens?

Pics? Lumens? :iagree:

Hi Guys...

I was down and out with a lower back injury for a few weeks there but I'm back to Bimmers now!

I brought home the a light meter so I can take some readings later when it gets dark out. Now I just have to find the stock bulb I took out :)

awesome, I was looking forward to the follow up because i'm getting cold monitoring disabled on the reverse lights in anticipation of doing this mod :)

Well Folks the results are in and they are hard for me to believe.....

And the OEM Bulb Results

I hard to believe when looking at them in person but the OEM has over twice the lights output.

I realize the perceived brightness was due to the change in color temperature but I didn't think it was going to be that much of a difference.

I will still keep running the LEDs because they look great and are bright enough for me but I might try a 15W HID kit in the future and see how I like that.

Oh damn, that is some stuff. Well actually nothing that we really didn't know really. Nice that there is proof. Thanks for doing this Lexicon.

damn.

Which stock bulbs were you using?

could temp have something to do with this? These seem dim in the cold....

still waiting for pics of your projector LED reverse lights :)

Glad I didn't place my order for LED backup bulbs.

how would these do in our housings, seller lists lumens on the meter in the listing too, maybe at almost 2 cm wide though they wouldnt fit through the opening?
