Hello,
This is my first post here, so apologies for any mistakes I made (I'm not a native english speaker so grammar mistakes are meant too
So, what is this all about. The basic things are already in the title. Half a year ago, I got a Ravemen PR1600 bike light. An all around fantastic light, but sometimes I do wish, the high beam especially, could be a bit brighter. I've contacted them to get some more information on the LEDs used and they responded very fast. The conversation was really friendly and I ended up making a few suggestions, which they forward to their R&D team. They also said, that I can always message them with new suggestions and that they are happy to get detailed customer feedback.
Well, my idea now is to roughly design a light how I envision it and send the design to them and if I have the time, maybe even make one myself.
So, here are the specs I could gather for the PR1600
- LEDs used are Cree XM-L2
- in neutral white
- limited to 800 Lumen
- kept at max 60°c (allegedly)
- I sadly couldn't get exact CCT, CRI or binning numbers
- powered by two 18650 cells (6Ah total)
What I want to do
- make the light brighter (whether that is through more Lumen, better CRI or another method)
- extend the runtime of the lower power modes
- I'll be using two 21700 cells (10Ah total)
- maybe change the lens a bit (though this is not the space nor the time to discuss that)
I've already searched for suitable LEDs and found some, but would really appreciate further input. Here are the ones I found
- Cree XM-L3
- Luminus SST-40
- Lumileds Luxeon V (sadly 4040 though)
I'm not really an expert on LEDs, so I don't know what the best way to approach this is. How many Lumen will I need (if the optics stay the same) to get a noticeable brighter light. Which CCT, CRI rating and bin are reasonable for this project and the like.
Thanks for any help in advance
Cheers CreepyShadow
