Instructions for LED DIY
1. Measure the inside bottoms of the front width of your cabinets, between the sides (called fences). This assumes that the upper cabinets are completely flat bottomed.
2. Create a box diagram of your pper cabinet layout on paper and include the measurements.
3. Decide how many lighting zones (circuits) youÂd like (groupings with their own switch or dimmer). Decide if you want dimming in each zone. You will need a transformer and a switch for each zone. Purchase dimmable transformers and switches for the zones that require dimming.
4. If you have lighting levels in your current kitchen you like, determine the lumens (light output) of those lights to be sure you are adding similar brightness. I used the following
Â Incandescent are typically 14 lumens per watt.
Â Fluorescents are typically 60 lumens per watt.
The lighting should be determined by a desired lumens per linear ft basis. The type of lighting (xenon, halogen, fluorescent, led, EL) possible could be dictated by conformance to local laws (eg - title24) FWIW, http://www.greentorch.com/LED-Strip-lights.htm has a claimed output of 83 lumens per watt. Environmental lights has their lumens here:
5. Determine the lengths of lights for each cabinet. You want at least one light every 30". Many have suggested getting the widest you can for each cabinet and then putting them on a dimmer to give you the most flexibility for task and ambient lighting. You can stack two or more lightbars parallel and connect them with jumpers for more lumens over a high-task area, such as a sink.
6. For each zone, add up the volts for the lights in the zone so you can select the appropriate transformer. Add 15% to your total. Here are the conversions I used (This is specific to the environmentallights type light bar)
Â 15 cm = 5.9" = 1.65w
Â 30 cm = 11.8" = 3.3w
Â 60 cm = 23.6" = 6.6w
Â 90 cm = 35.4" = 9.9w
7. Decide where you will place your transformer(s). Transformers should be placed in a wall, but in a cabinet, basement or attic where there is circulation and you can access it, if needed. You need one transformer for each lighting zone. By code, the transformer(s) have to be in an accessible location. One transformer per lighting zone is required if independent control of each zone is required. If multiple transformers are required, you need to ensure that there is adequate electrical branch wiring to the locations where each transformer is located. The necessary switch controls need to be planned for.
8. Add your lights to your box diagram. This will help you determine the accessories needed and where to place the wires. The lights in each zone must connect to each other and each cable must reach the transformer. For new installs, you can pull the wires back through the wallboard. For existing installs, bring the...
