Electrum

Electrum is an application designed specifically for the BlackBerry PlayBook. Lighting designers, engineers, architects, and anyone interested in lighting may find this program useful. Electrum includes four distinct lighting tools: Lamp Life Calculator, Inverse Square Law Calculator, Lux Conversion, and a Glossary of Lighting terms.

The Lamp Life Calculator allows the user to see how Voltage variations will affect the Lamp Life and also the following characteristics: Wattage, CCT, and Lumen output. The calculations are based on the IESNA Lighting Handbook. Results are displayed in a scrollabe grid.

The Inverse Square Law Calculator allows one to determine the Illuminance of a light source at a certain distance.

E1 the known Illuminance value.
D1 distance at which E1 is known.
D2 the desired distance.
E2 the result of the calculation. The Illuminance at distance D2.

E2 E1 D1/D2^2.

Lux Conversion allows the user to convert values from Lux to footcandles and from footcandles to Lux.

The Lighting Glossary is displayed in a scrollable list. There are also buttons for which the user can select to jump to a particular letter.
