1000 Lumen Versus 230 Lumen Tactical Flashlight

This is a comparison of an UltraFire WF-502B 1000 lumen and a Vizeri VZ230 230 lumen tactical flashlight. For the comparison, we are utilizing identical 18650, 3600 mA lithium-ion batteries that were charged in the exact same charger. The UltraFire has a CREE XM-L T6 led unit and the Vizeri a CREE XR-E Q5 LED. These flashlights have an identical interface. They both have the exact same 5 modes that are switched by means of the on/off button, and a memory feature to remember the last mode. The UltraFire does not have the capability to alter its focus, whereas the Vizeri has a zoom focus. We took temperature level measurements at the start then at numerous points along the test. Their cool beginning temperature level was about 81 degrees Fahrenheit. With both lights turned on and running for 14 minutes, the temperature level on the UltraFire increased to 154 degrees, which is far too hot to hold. The Vizeri light was at 104 degrees, which would feel warm to your hand. At 19 to Thirty Minutes the UltraFire reached its highest temperature level of 158 degrees, and the Vizeri reached 112 degrees. Another test at 27 minutes revealed the Ultrafire was beginning to drop a little, while the Vizeri reached its highest temperature level of 112. At an hour and 17 minutes the UltraFire is nothing but a faint glow. It started to get dim around 1 hours and 5 minutes, but we ran out of storage on the camera. So we chose to charge the batteries overnight and run the test once more. On the second run, somewhere in the very first 20 minutes the UltraFire totally died. It obviously hit its 158 degrees external temperature level and fried something inside. Upon taking it apart we discovered that it melted the wires inside to the integrated circuit that controls the functions. Quality 1000 lumen lights, which cost around $160, have a "step down" feature to safeguard them from heat buildup.…
