C101 99.99% pure oxygen free copper thermal conductivity: 391 W/m · oK
99.9% pure silver plating thermal conductivity: 418 W/m · oK
LEDs directly mounted to silver plated copper surface. No MCPCB insulation layer. Lowest thermal resistance path possible without extremely exotic materials (e.g. diamond)
6061 T6 aluminum thermal conductivity: 167 W/m · oK (Heatsink)
Pure aluminum thermal conductivity: 220 W/m · oK (MCPCB)
Bare aluminum for best conduction of heat into host. MCPCB screw torqued to 32 in-lb. creating a clamping force of over 1000 lbs.
Arctic Silver 5 thermal paste applied between MCPCB and heatsink.
Carclo Tight Optic: Brightest overall. Excellent "wall of light". Larger spot
with good flood.
Copper sink 5.6A = 1654 OTF lumen
Copper sink 4.2A = 1357 OTF lumen*
Aluminum sink 5.6A = 1489 OTF lumen*
ALuminum sink 4.2A = 1278 OTF lumen*
Carclo Spot Optic: Between Carclo Tight and Khatod optic. More output but a
sacrifce in beam shape compared to Khatod.
Copper sink 5.6A = 1572 OTF lumen
Copper sink 4.2A = 1290 OTF lumen*
Aluminum sink 5.6A = 1418 OTF lumen*
Aluminum sink 4.2A = 1214 OTF lumen*
Khatod optic: Tightest spot, most throw, more traditional flashlight beam from a
multi LED engine. Less output than Carclo due to more collimation of the light.
Copper sink 5.6A = 1404 OTF lumen
Copper sink 4.2A = 1152 OTF lumen*
Aluminum sink 5.6A = 1263 OTF lumen*
Aluminum sink 4.2A = 1085 OTF lumen

These light engines can be dangerous. If left unattended, one could get hot
enough to cause a failure in the battery, resulting in a possible fire or
explosion. Do not point light at eyes or skin. This is a very high power device.
Do not run unattended. Thermal shutdown designed for emergency shutdown only.
Always lock out tail-cap when not in use to avoid unintentional turn on. Only
use High quality Li-Ion cells rated for the current draw of the light engine. No
responsibility will be taken for any damage done, personal or punative, by the
extreme power of these light engines. You agree to this upon purchasing one.
FETtie high current switch
Introducing the ultimate high power tailcap switch for Z41 and FM26XXX hosts.
Designed as a suppliment to the P60 Quad drop-in, This switch's capabilities extend well beyond it's originally intended necessity.
With ANY Linearly regulated or Direct Drive light, this will reclaim power currently being eaten by your higher resistance switch/spring, and give you more current, and more lumens.
With ANY Buck, Boost, or Buck-Boost regulators, this will reclaim power currently being eaten by your higher resistance switch/spring, and provide longer runtimes.
How does it work?
The FETtie uses a solid state semiconductor, a MOSFET. Essentially a relay, with no moving parts, which is turned on by the clicky switch. The Clicky switch itself only conducts 100 nanoamps, that's 0.0000001A, to activate the semiconductor. This means the clicking mechanism will last nearly forever, as the electrodes will not wear from arcing.
The FETtie uses a small coin battery, 1216 size. You do not need to worry about this battery becoming depleated however. It's like the battery in a watch, it will last for many years. Even being left on, the switch will draw less current from the coin cell than it's self discharge rate
Current - 25A+
Voltage - 20V MAX

Here are some graphs to illustrate the difference in output using a FETtie vs. a McClicky at 4.2A These results would be much more profound at 5.6A and above.
Review and OTF measurements done by Run4jc:
$165 for 4.2A Aluminum sink, any modes, any optic.
$190 for 5.6A Aluminum sink, any modes, any optic.
$285 for 4.2A Copper sink, Khatod optic, any mode. Carclo optic +$10
$310 for 5.6A Copper sink, Khatod optic, any mode. Carclo optic +$10
(Carclo optic is smaller, therefore there is more silver/copper used and thus the extra $10)
$48 for FETtie switch
Special order R4 5000K LEDs incure an extra $15 charge because I do not buy them in bulk, and receive no discount that I can pass on down.
All drop-ins ship with a Q-tip and some Artic Silver 5 thermal paste to apply to your host drop-in socket for maximum heat transfer and maxmium peformance from your drop-in.
Please take extra care when handling the exposed optic. Mishandling of the optic can decrease output. Never directly touch the optical surface with bare hands if optimal output is desired.
