The VaraLight mod is an experimental prototype light designed to
push the SST-90 LED to it's maximum allowable limits, and then
some, using only common NiMh batteries.
VaraPower Series Cautions and Warnings
Varapower
The VaraPower series flashlights are high power modified flashlights

The flashlight will become hot quickly when operated at, or near maximum output on 4 C NiMh
cells. This is a function of the heat produced by the LED running at 30+ Watts and the physical
size and mass of the flashlight. If the light gets hot, turn it down or off and let it cool down.

The flashlight can become hot when operated at, or near maximum output for extended times on
3 D NiMh cells. Always observe caution when light is operated near maximum output.

Never leave the light running at or near maximum output unattended
Never allow children to operate or handle the light; it can reach temperatures in excess of 160F,
hot enough to cause burns

Never substitute different battery types or combinations - NiMh cells only!
NEVER use Lithium or other type batteries in the VaraPower Mod; lithium cells may explode,
burn, out gas, burst, or otherwise go into thermal overload

Never make configuration changes or alterations to the flashlight
For example, DO NOT copper strap the tailcap spring in the flashlight. The small resistance in
the spring is critical to limiting peak LED current

The VaraPower flashlight can produce intense light
Never look directly into the light, or shine in another person's eyes
Do not allow children to operate or handle the light; it produces intense light capable of causing
eye injury

The tail cap spring can become very hot when the light is operated at or near the maximum
output level. Use caution when opening the flashlight right after use; spring can burn you.

Use common sense - you are in control

The flashlight has a power control circuit built into it. Use it to turn down the light if it starts
getting too hot to hold.

Seriously, please do not substitute battery types or combinations. And respect the light for the
high power lighting device it is, and use with common sense; it's very bright and can get very hot.
