I saw this awesome warning recently few days ago:
This flashlight poses a risk of personal injury and property damage if not handled and operated with great caution. This light is not a toy and should not be used by or entrusted to anyone other than a knowledgeable and cautious individual. Heat: The very high current from the battery and to the LED generates a great deal of heat very quickly, and the relatively low mass in this very small flashlight prevents heat dissipation at a rate that would permit extended operation of the light at a high output level. When driven to its output capacity, heat reaches a level making the light too hot to hold within minutes or less. Either the light should be turned off or Peak™s proprietary QTC system should be used to reduce the output before this happens. If left unattended, build-up of heat could reach the point of ignition of nearby flammable objects. This light should never be operated at high output unless in the hand of an alert operator prepared to quickly reduce current and output. Batteries: All batteries are affected by heat and current draw, and if either becomes too great, a battery can be damaged. At a minimum, battery life can be significantly reduced. At worst, failure could be explosive. BATTERY FAILURE CAN OCCUR DURING USE, OR DURING ANY SUBSEQUENT RECHARGING OR USE. A protected battery is no guarantee against this. Regularly check batteries after use for signs of excessive heat. Always closely monitor the recharging process and follow safe practice procedures: use a quality charger; charge in a safe location, check status frequently; terminate the charge timely; inspect and test the battery after charging. IMR (LiMn) batteries are believed to safely handle currents much greater than any other battery chemistry and are therefore the preferred battery for this light. Other Li-Ion 10440 batteries are not designed for high current applications and when used in this light can be driven to the very limits of their design. Only new batteries of good quality should be used in this light. Battery voltage should also be checked regularly. At the first sing of reduced capacity or other problem the battery should be retired. Under no circumstances should this light be operated before the user has studied the important materials readily available on the subject. We suggest that users follow the advice and instruction posted throughout the CPF Forum and in the CPF Marketplace by respected dealers.
To some people, this warning makes the light in question even more attractive! The light can be used as a fire-starter in a survival situation and keep you cold in winter.
I understand that these warnings are to limit liability and are a byproduct of our litigious society, but that doesn’t mean we can’t enjoy them!
