forsh, since they have all the sense resistor pads bridged with zero level resistors the only way I can see to improve output is through a better MOSFET. That may be difficult to find in the package they used, but there are some or have been.
We used to use one that I still have a few of, back when Comfychair started hacking 105C drivers into FET controlled direct drive. The numbers are in my mind but jumbled, something about N and 0 and 7… lol (memory, totally sucks) I’ll see if I can find em and let you know what to look for.
I remember they were getting scarce at one point, and MTN only had a few left in stock so I ordered a couple. Never used them because right at the same time I kind of got out of modding for a good while. Bought a ZL SC63w at the time and that kept me satisfied for quite a while…
I recently picked up an Olight S1R Baton II to use at work because I like the tiny form factor and the magnetic charger is great for quick top-offs when I swing by the desk. I work in a semiconductor fab and the overhead lights have UV filters on them to protect the wafers during the photolithography process. This makes the ambient light look very yellow. The S1RII’s cool white low CRI emitter looks positively horrid in these lighting conditions, so I decided to swap it.
I swapped in a 3000K 90+ CRI XM-L2 (XMLBWT-00-0000-000UT20E7) and was very pleased and surprised to see that this is one of the most beautifully tinted emitters I’ve seen. I measured it with a color meter and the tint measures almost exactly the same as a sw45k. I wasn’t expecting that but it looks absolutely lovely. I want to order a few more but I’m afraid they’ll end up being from a different tint bin.
Rayoui, where did you get that emitter and when? Mouser? Interested as I have a few lights with picky reflectors that only seen to like doomed XML2s… never found a non-80/85cri tint I liked in this emitter… found the answer in another thread.
And I did some stuff as well. Modded my FW3A with an S21A reflector that I machined down to clearance the head. I’ve been trying to source one of these reflectors for so long and finally broke down and bought a host from MTN. Turns out I really like the s21a as well, but it’s going to turn into a long runtime LH351d triple/quad soon enough.
HB4 is above the BBL. No wonder why it’s so green. KD used to sell a HD2 bin that was somewhat rosy. I was assuming it was the HD2 bin because it’s more popular so I was surprised how the XM-L2 appeared that much rosier.
Even without comparing it next to another light, this particular XM is one of the pinkest LEDs I’ve seen. It measures about the same tint as my sw45k lights. I can take a comparison photo with some slightly rosy XP-L HI in 3000K when I get home from work.
