This is a bit of a braindump of information that hopefully will result in an improvement to the lighting of the space and lowering the maintenance level / cost of hacking. | This is a bit of a braindump of information that hopefully will result in an improvement to the lighting of the space and lowering the maintenance level / cost of hacking. | ||

We're not going to create our own foundry to create LEDs, but we will want to (quickly) evaluate the levels of building versus buying LED arrays/drop-in replacements | We're not going to create our own foundry to create LEDs, but we will want to (quickly) evaluate the levels of building versus buying LED arrays/drop-in replacements | ||

* the tube replacement things are no match for properly designed luminaires and not much cheaper. (Phil) | * the tube replacement things are no match for properly designed luminaires and not much cheaper. (Phil) | ||
* I had a look at replacement tubes in B&Q. They have Osram tubes that don't require balast replacement. 5' tubes are £25 each and consume 22W with 1800lm output at 3000K. Fluorescent tubes were £9 each and consume 58W for 5200lm at 4000K. So the LEDs are 82lm/W vs 90lm/W for the fluorescents. So they're not going to pay the 2.5 x cost off, and might require extra fittings. Confirms phil's opinion. (artag) | * I had a look at replacement tubes in B&Q.

=== Womble (Procure Freely) === | |||
* Many modern offices in London replace lighting at a far faster pace than the fixtures' duty cycle. This means free fixtures (and bulbs!) become available. | |||
** These fixtures are often 10 years old or less and can be quite energy efficient, using smaller bulbs. | |||
** Mentar was successful at acquiring some modern fixtures which were very nice - we installed one in the washroom part of the green toilet/store room. | |||
