Illuminance
Traditional photocells (also called light-dependent resistors or photoresistors) only have a luminance range of less than 10,000. As can be seen in the table below, this only covers a very small range of the ambient light that we encounter every day, which has a maximum range of 130,000.
A traditional light-dependent resistor
| Illuminance | Example |
|---|---|
| 0.002 lux | Moonless clear night sky |
| 0.2 lux | Design minimum for emergency lighting (AS2293). |
| 0.27 – 1 lux | Full moon on a clear night |
| 3.4 lux | Dark limit of civil twilight under a clear sky |
| 50 lux | Family living room |
| 80 lux | Hallway/toilet |
| 100 lux | Very dark overcast day |
| 300 – 500 lux | Sunrise or sunset on a clear day. Well-lit office area. |
| 1,000 lux | Overcast day; typical TV studio lighting |
| 10,000 – 25,000 lux | Full daylight (not direct sun) |
| 32,000 – 130,000 lux | Direct sunlight |
However, the latest technology has enabled new light sensors, which cover a luminance range of up to 55,000 lux. Although still far from the range of the human eye, this covers most of the ambient light we see on a daily basis.
The good news is, Tritium now contains this technology! This will allow Tritium adjust its brightness to be easily seen in the intense summer daylight where we do most of our jumps, and dim to an appropriate level for night jumps – and everything in between. Even better, Tritium will do all of this automatically.
We’ll make sure that Tritium will not only look awesome, but also that it will be the appropriate brightness for all situations! So if you haven’t signed up for it yet, what are you waiting for?
Tritium will set its brightness depending on the light conditions – from the brightest noon sun to night jumps, and everything in between!
