Was the shipping from England expensive?
Thanks for the tip
That's who I was referring to.

This makes me wonder if the lens itself is the main reason the TR-38 appears a little better. I'm not convinced at this point that the 2,000 mw pill is superior, but the combination of it and the 38mm head is very good.
6mm06 it surprises me that the 38 is better than the 50mm from LL, must be the lens.
As for lens size with all components being equal the larger the lens the tighter and brighter the beam will be when fully focused. As components vary the performance varies.
I found this on another site
The LED driver current (usually 1 amp for an oslon) sets how bright the LED is.
The diameter of the lens controls how tight the beam coming out of the torch is.
Larger diameter lenses catch more of the light from the LED and squeeze it into a tighter beam so it illuminates further.
From long range to short range
T74
66
50
Doubled T20
Basic T20
The voltage has no effect on brightness as long as your battery has a voltage within what the driver can work with.
Many drivers are 3-6 volt, so use a single 18650
Other drivers are 6-18 volt so can use a 12v battery
connect a 12volt battery to a 3-6 volt driver and it dies instantly
Connect a 18650 to a 6-18 v driver and won't illuminate the LED
The T74 I have came from Ian Sirrel ir.light.build@gmail.com
It has a 3 mode driver running from a single 18650 battery
It's the longest range illuminator I've ever used - eyeshine from bunnies at 500 yards.
I would also look for this emitter and stay away from lights that don't list the LED.

If you can solder at all, you can build your own flashlight with different modes. If you want a dimmer in the tailcap (which could be very useful so you don't wash out your NV picture), HTRN sells just what you need with the T20 Infinity.
IMO the best deal going right now

This conversion will also include the new Osram 4715AS IR 850nm LED rated at 1,400 millampere (mA) since the 3 mode LEDs will not work with the rheostat switch. If anyone wants one converted just send it to me with your check or cash to:

Please also send me an email at hightechredneckinc@gmail.com so I can keep track of what is coming and going.
Thanks, Kevin
And yes those new clip-ons look promising, all the features are nice but will drive up the price.
