Light Output – Lumens
Is a measurement of the total amount of light produced by a source(s) and in this case a LED or multiple LEDs, measured in a calibrated integrating sphere between 30sec and 120sec.
Typically this kind of sphere measurement is performed on an LED at the chip level and it is this data that is used for advertising the lumen output before any application of optics or reflectors.
Not in our case, because of the method we build our flashlights we take this measurement after the optics have been attached.
Peak Beam Intensity – Candelas
Peak Beam intensity is the strength of the light beam at its brightest point and measured at a specific distance measured, 2m, 10m, or 30m, while on its highest output mode.
- The ANSI FL-1 Standard requires this measurement to be taken with a fully charged battery and within 30 seconds to 2 minutes of pressing the power button.
- To convert LUX to intensity (candelas), Lux is multiplied by the square of the distance between the source (flashlight) and the target (lux meter). The intensity of the flashlight does not change with distance. A 700LUX reading measured with the flashlight 2 meters away yields an intensity of 700*2m^2=2800cd. 1Lux = 1 Cd at 1m.
Trinity’s light beam is a uniform, high powered, high density light pattern and therefore the intensity, the candela measurement, is the same within the square pattern.
Beam Distance – Lux Throw
The light beam distance is an ANSI FL-1 Standard which focuses on the brightest output portion of the light beam, measured in meters, when the output brightness equals the same light output as a full moon, which is 0.25lux.
It is very difficult to take this measurement accurately so a standard calculation is used to determine the light beam distance (throw) of a flashlight output. The distance is equal to the square root of the beam intensity (candelas) divided by 0.25lux, such as ²√(2800cd/0.25lux) = `106m.
Battery – 18650 Li-Ion Rechargeable
- Lithium Ion batteries are becoming more common place and can be found in many electronic devices used on a regular bases such as laptops, cell phones, cordless power tools, and cameras.
- Lithium Ion battery, including the 18650, can be dangerous under certain conditions and because of this the 18650 uses circuitry to manage the recharging process so that there is no overheating of the battery.
- Lithium Ion batteries, including the 18650, may be dangerous under certain conditions. TLMI designed circuitry to prevent overheating during the recharging process.
- Damage to the battery or the internal charging circuit may cause the battery to rupture or explode. Dispose of batteries that have damage to the casting and consult with TLMI if there are problems with the charging circuit.
- 18650 batteries may be recharged a minimum of 500 cycles and is dependent on usage, storage temperature, drain level during usage, and duration of excess charging with the charger.
- Battery storage should be in a cool dry place preferably between 20-25C (68F to 77F). If the flashlight will not be used within a year, TLMI suggests removal of the battery from the housing and properly stored.
If you are storing this for emergencies then it is best to check it or top off the charge every 6 months.
Draining a rechargeable battery to very low voltages causes longer recharge times and reduces the life span or number of recharge cycles of the battery so it best not to use the battery below 2.8V on a regular bases.
