Vinh,
Could a similar circuit be used on the BLF GTvn90?
I have no plans for this right now. GTvn is a 8 cell lights. Having 2 set of 4 cells in series with ultra high drains unprotected pushing tremendous power greatly increase the risk of various aspects. If such a design were implemented there will be EXTENSIVE testings and development before such application. GTvn is currently pushing an average of 1.6-1.7 Mcd. This is achieve using an all parallel design. The safest design possible for mass production. The light is also extremely versatile being able to run on any number of cells from 1-8. With a crazy driver may be we can hit 2Mcd. But its at a gain the eyes wont differentiate much while incurring great unprecedented risk all while losing the flexibility of cells configuration.
I know that even with the default circuit, it is around 1.75 Mcd, which is already incredibly high, but one can only hope for even higher numbers.:naughty:
As for the TN42vn, I'll soon purchase one with the Oslon LED.
Tn42vn Oslon is a dream thrower. One I adore beyond all of my current thrower offerings. The throw is INCREDIBLE. There is no heat to worry about. The light is extremely safe. Price is somewhat relatively fair. Also being a reflector thrower the beam is practical with general use as oppose to aspheric. CFT90 + developing driver will make the desirable level even higher at the cost of excessive $$$ and heat.
To be fair I would pick a TN42vn any version over a BLF GTvn any version if I can only have one light. The GTvn90 performance is amazing but the size is more or less amusing.
