Massdrop sells Lumintop tools that always start on low mode, @about 3 lumens, medium is about 20 lumens
for medical use, I encourage you to consider a copper Tool, although they are heavier, because copper is naturally germicidal and even kills MRSA.
your IYP is really an excellent light, if you like the 2xaaa size, I think you did the best you can do, regarding the LED from a stock light, particularly because newer models no longer offer the 219b
The Optisolis and E21a LEDs that Clemence offers are in a class way above the Nichia LEDs in the Lumintop Tools.
I strongly recommend the lights Clemence is selling, if the lumen levels meet your needs. The color of the beam, and the fact that it can be diffused evenly without a hotspot glare, makes them absolutely the best, and most exceptional choice you could make, in terms of light spectrum and beam quality.

(about money: I agree it is unfortunate that shipping is expensive, maybe you should buy more than one, to reduce the unit shipping cost… LOL… then you sell one to a friend, and become a Hero who brings High CRI Light to illuminate your corner of the world ;-))
