Divers who want a slightly wider beam for general purpose use, lighting larger areas, would benefit from the 4TEC's brother the LFM 7XPG which has 7 smaller crees but boasts 2800 lumen at 6500 kelvin at a 12 degree angle.
The difference: 4TEC less lumen but more light in a smaller zone (i.e. more light in a square metre) and 7XPG more lumen but wider distribution of light and beam.
BATTERY PROTECTION MODULE
Operating method (on example of 24V battery pack): When the power supply is on, the module automatically recognizes the battery pack type (24V / 14.4V) and loads proper parameters from settings memory. Next it switches to „standard” operating method in which it regularly measures battery pack voltage (30 samples every 1 sec).
a) Charging
During the charging process, when the maximum voltage is exceeded (28.6V), the charging entry is disconnected. The charger is still able to measure the battery pack voltage so its working stays undisturbed. Connecting the charger again and supercharging the battery pack is possible after the battery pack voltage is lowered to 27.1V (max hysteresis).
b) Discharging
During the usage of the battery pack (discharging process), its voltage gets gradually lower until the value of 21.5V. At this point the protection module indicates getting to the complete battery pack discharge level by flashing the light for 5 times (temporary stops in circuit load).(Upon reaching the minimum voltage level (20.0V) the load gets completely disconnected in order to protect the battery pack against deep discharge.(Connecting the load again is possible only after charging the battery pack to voltage of 21.5V (warning of discharge).((The process of charging and discharging for 14.4V battery pack proceeds in a similar way, the module reacts to the voltage values shown in the table above.

Underwater ExplorersDirDirect is a world-leading online dive shop run by Underwater Explorers based in Portland, Dorset, UK. Underwater Explorers is a dive centre with a striking difference. It was born out of the concept of "Hogarthian" diving, safe and streamlined equipment configuration, using the most robust products available for recreational and technical diving -- but at the same time, keeping it simple. It is based on the concept of "less is more" in diving and acts as an equipment outlet, training facility and source of sound advice.
