This is the exact flux pen my local RS carries, if you have prime it should be about the same price as buying local.
for flux paste I use this from eBay, came in 3 days from a wearhouse in NJ. I went to a few places looking for it local before ordering (there are actually several different large electronics stores in the area, none carried solder paste and only one employee knew exactly what it was).
Added diffuser film sizing to the OP. I’m glad I have a bunch of random world currency to use as cutting stencils.
So, my original idea a while back was to ask RMM to do a S3-triple with three different tints, to get a wide-spectrum light the size of a cigar. And it’s almost time for him to open up his modding service again.
Looking through his current stock, here’s what looks like the best option:
XP-G2 R5 1A, ~6700K, 518+ lm at 1.5A
XP-G2 R4 5A1, ~4100K, 485+ lm at 1.5A
XP-G2 Q2 7C4 90+CRI, ~2900K, 288+ lm at 1.5A
This should provide the widest and most evenly-spread tint selection from what is available right now, and should result in a blended overall tint of just under 4900K.
That tint estimate was calculated by averaging the three tints multiplied by their relative output values/bins. ((6700 * 100) + (4100 * 93) + (2900 * 55)) / 248 == 4882 Kelvin
Using the same type of calculation on the BST-wide, I get about 4843 K:
(6700 + (4900*0.93) + (4200*0.80) + (3100*0.80)) / 3.53 == 4843 K
I’m not sure which Carclo lens would work best. The 10507 is described as “narrow spot beam that is very smooth all the way through with no discernable hotspot”, 10508 is “very floody”, and 10509 is “extremely floody”. I assume one of the three would be best, but it’s hard to say which.
As for power level, I’m guessing 4.4A total would be ideal, since that drives each emitter at nearly 1.5A, so it should make the tints as close as possible to the manufacturer’s specs. Also, it’s a nice balance between lumens and heat, and I think it would do about 1100lm OTF on turbo if the optics lose 12% of the output. (518lm + 485lm + 288lm) * 4.4A/(3*1.5A) * 0.88 == 1110 lm
WOW! Awesome build…very cool!
Very nice. That is something I’ve been considering with my EYE40. It comes on one emitter at a time progressively until all four are active. It would be nice to start with a single HiCRI coming on first and then moving into cooler tints until I reach U2 1A on the fourth emitter.
Nice work Toykeeper!
