Edward is living in a world he can't afford and to which he doesn't belong. To camouflage himself, he has catered to his friends' needs: fetching drycleaning, sorting flowers for premieres. It's a noble effort, really - anything to keep his perfectly awful 'best pals' Robert and Stanza happy. In return, his proximity to their abundance might sponge the shame of his birth and violent past cleanly away.

But Edward has - secretly - been in love with Stanza since their Cambridge days. The shattering discovery that Stanza and Robert are an item pushes him too far. His little acts of kindness take a sinister turn, giving way to the unspeakable brutality Edward fears is at his core.

Are there limits to what he will do for his friends? Are there limits to what he will do to them?

Battery Voltage Indicator
When the light is turned on, the built-in power indicator under the stainless steel side switch will show different color light to indicate remaining battery voltage:While battery voltage > 10.2V, blue light turn on and last 3s.
While battery voltage 9.6V-10.2V, purple light turn on and last 3s.
While battery voltage 8.7V-9.6V, red light constant-on.
While battery voltage < 8.7V, the light turn off authomatically.
* Low voltage warning
When the battery voltage level drops below the present level, the light is programmed to downshift to a lower brightness level until lowest output is reached. When the battery voltage level still drops low under lowest output, it will shut off authomatically.
Intelligent Overheat Protection
Advanced intelligent temperature regulation technology allows MK38 to dynamically adjust output performance according to its body temperature.The light will accumulate a lot of heat when you use it at high-output levels for extended periods. When the light reaches the temperature of 65°C or above, the light will automatically step down its output to reduce the temperature. at the same time we also make more premium cooling fins on flashlight head and built-in duable-row fans to blow effectively these cooling fins through the outside to protect flashlight overheat.
* Note: DO NOT submerge the flashlight into any liquid when it is hot. Doing so may cause irrepareable damage to the light due to the difference of air pressure inside and outside of tube.Note: We also high recommend the oridinary users to purhcase Samsung 40T unprotected flat-top 21700 batteries or Modell P42A unprotected flat-top 21700 batteries to drive MK38.

Battery Voltage Indicator
When the light is turned on, the built-in power indicator under the stainless steel side switch will show different color light to indicate remaining battery voltage:While battery voltage > 10.2V, blue light turn on and last 3s.
While battery voltage 9.6V-10.2V, purple light turn on and last 3s.
While battery voltage 8.7V-9.6V, red light constant-on.
While battery voltage < 8.7V, the light turn off authomatically.
* Low voltage warning
When the battery voltage level drops below the present level, the light is programmed to downshift to a lower brightness level until lowest output is reached. When the battery voltage level still drops low under lowest output, it will shut off authomatically.
Intelligent Overheat Protection
Advanced intelligent temperature regulation technology allows MK38 to dynamically adjust output performance according to its body temperature.The light will accumulate a lot of heat when you use it at high-output levels for extended periods. When the light reaches the temperature of 65°C or above, the light will automatically step down its output to reduce the temperature. at the same time we also make more premium cooling fins on flashlight head and built-in duable-row fans to blow effectively these cooling fins through the outside to protect flashlight overheat.
* Note: DO NOT submerge the flashlight into any liquid when it is hot. Doing so may cause irrepareable damage to the light due to the difference of air pressure inside and outside of tube.Note: We also high recommend the oridinary users to purhcase Samsung 40T unprotected flat-top 21700 batteries or Modell P42A unprotected flat-top 21700 batteries to drive MK38.

Battery Voltage Indicator
When the light is turned on, the built-in power indicator under the stainless steel side switch will show different color light to indicate remaining battery voltage:While battery voltage > 10.2V, blue light turn on and last 3s.
While battery voltage 9.6V-10.2V, purple light turn on and last 3s.
While battery voltage 8.7V-9.6V, red light constant-on.
While battery voltage < 8.7V, the light turn off authomatically.
* Low voltage warning
When the battery voltage level drops below the present level, the light is programmed to downshift to a lower brightness level until lowest output is reached. When the battery voltage level still drops low under lowest output, it will shut off authomatically.
Intelligent Overheat Protection
Advanced intelligent temperature regulation technology allows MK38 to dynamically adjust output performance according to its body temperature.The light will accumulate a lot of heat when you use it at high-output levels for extended periods. When the light reaches the temperature of 65°C or above, the light will automatically step down its output to reduce the temperature. at the same time we also make more premium cooling fins on flashlight head and built-in duable-row fans to blow effectively these cooling fins through the outside to protect flashlight overheat.
* Note: DO NOT submerge the flashlight into any liquid when it is hot. Doing so may cause irrepareable damage to the light due to the difference of air pressure inside and outside of tube.Note: We also high recommend the oridinary users to purhcase Samsung 40T unprotected flat-top 21700 batteries or Modell P42A unprotected flat-top 21700 batteries to drive MK38.
