What did you mod today?

I agree, did not notice much diffusion, just coloration…

Very helpful. Thanks for helping me to understand better… all the colors are being reduced by the filter, but at that reduced level, they are more balanced (R9 goes up and the others appear to also increase)

agree

thanks, I did not know, was only addressing mattlward’s LH351d “low pop LH351d” solutions

you have convinced me mattlward should try a filter

I volunteer someone (Rayoui?) to sent mattlward a piece of Zircon 803 :wink:

I’d be willing to donate a piece of 803. I can also spare a piece of 802 and 804, for science.

:beer: :+1: :person_with_crown:

It would be interesting if the effects of each were tested.

I have an FW3A setup with sliced 351d’s, the dogfights. It is very nice indeed.

Here is a great post by maukka comparing several Zircon filters and some standard minus green filters.

Hi Xandre,
How do you keep the fresnel lens flat? It is really big but still thin plastic. Is it mounted all around in a stress-free way?

And what is the parabolic part of the body made of?

Thanks for the link Rayoui - very interesting read.

Swapped the emitter in my SF A2. CRI/R9 is great :smiley:

I’ve got some high CRI warm white 5mm LEDs on the way with which I’m going to try swapping the secondary LEDs (currently red). That should make for an interesting amalgamation of new and old world tech, especially with its buck converter driven Xenon lamp.

Well guys, about my most lame mod ever… I have been having eye problems and could not see to mod. Don’t know if I will ever get back to building my own drivers or not.

I have been on a kick with AA/14500 lights lately, not much out there with a decent driver. Now, I love the P60 modules for testing new emitters and drivers, way back in my P60 bin I had a Solarforce .8-4.2V XP-G R5 dropin. As you could guess, from Solarforce a very low drive current, crappy CW emitter. But, 3 decently space modes!

To me, this was almost no use because of the existing emitter. Given that high mode on 14500 is only about .9 amps, I decided to use something with a fairly low Vf… this required Nichia of course. I have them all from sw-30, sw-40, sw-45, sw-45k and sometimes multiple bins, my favorite emitter, But, my eyes… so I found that I had 2 sw-40 D200 already on Noctigons… Swapped out the nasty XP-G, wire soldering was bad enough. But now I have a very low voltage dropin that I swear now has a bit more output and makes my eyes happy.

The copper tape on the dropin is cut and folded back on itself to all for a better fit in the FiveMega 18500 tube. It was not making reliable contact without it. Someone told me there is a fitment ring made that drops in on top of the dropin, under the retainer that would likely fix that issue. According to FM the tube is SolarForce parts compatible, that switch and one other are the only 2 that I had that would screw on the tube. I was really bummed by that as I really want this to tail stand as it is a SHTF light for me. Overall, I am fairly happy with the final product.

I have Convoy low voltage drivers on the way, if they ever get here… I will test them in a shell, they will take more work as they are springless, I will either cut as solder a longer brass pin on the driver or see if the old AK springs will fit and find a longer version of them for the driver. But, the Convoy driver is 4 mode and a bit higher current draw. A good while back I built a dropin based on the Jaxman M2 driver for 2xAA operation and I am reasonably happy with it as well.

On an interesting side note, I compared all of my ECD 4000k lights in low modes to this dropin… Most look sick! I have lights with 2 bins of SST-20, 2 bins of Lh351D and with XP-L 5A3 and 5D2. Of all of them, the 5D2 was about a perfect tint match, but much lower CRI. All of the SST’s and one of my LH351D’s looked down right yellow green next to this emitter.

Anyone have an extra one of this dropin? I would really like one more, not sure why I only bought one at the time. I guess I figured SolarForce would be around forever.

Thanks Xandre, that sounds good. Nice beam, it looks like it will be a bit of a rainbow around the focus, like I had with my XM-L2 36cm fresnel box, but I hope it will still be a good spot :slight_smile:

I’ve been trying to get Convoy 12V boost driver with current sense resistor value halved to work with XHP70.2 on 12V MCPCB. Well, not a success. It lits up and is quite bright, but I can’t change modes. Few taps and nothing happens, few more and it flickers. 20 taps and I can get to config mode and change groups. If I use GT-FC40, the driver works just fine. Can’t really tell is it brighter than with stock driver. At least it works. So partially success?

Half the value will double the current, was that what you wanted to do ? It might hit the switch current limit and some components might be undersized for it.
Which driver is it, is it originally for 6V or 12V?

Yes, that was what I tried to do. It is meant for GT-FC40 and is 12V boost driver. I was trying to use it as a 12V 5A driver for XHP70.2. Didn’t work. For GT-FC40 it did work. Molicel P42 is the battery I used.

I see you had to drill the reflector...How's the beam?

Very floody. :smiley:

I know, i have XHP70.2 in my S21B but I didn't drill the reflector.

Any beamshots?
