mentar's LED lighting proposal

Given the cost and lack of reliability of the current lighting fittings at the space I'd like to propose we run a small trial with custom built LED arrays?

• 

  Adjustable constant current driver

• 

  3watt star leds

• 

  Galvanised steel stud

Approach

The approach I'm proposing is to use 3 watt star leds mounted on the inside of galvanised steel channel. The led driver is a an adjustable constant current source, this can allow us to use varied power supplies to power the strips including some of the old laptop chargers that have been gathering dust downstairs for some time.

Pros/Cons

• Pros
  • Relatively cheap
  • Reliable in theory (including overtemp and shortcircuit protection)
  • The galvanised steel stud provides a basic reflector and heatsink while the lip allows mounting of diffusion plates. Can also be used as the ground plane, simplifying connections.
  • Makes use of a range of un-needed power supplies

• Cons
  • Requires some effort to put together
