Useful Tools

Here's a list of useful tools which will greatly help working on lights:

•Digital multimeter ($10-$200) – buy one with (LED) diode test and AC current functions (photo).

•Soldering iron & rosin cored solder [1.6mm diameter, 60/40 grade] ($40) It's best to buy a variable temperature type because the temperature can be set to suit size or type of job.

•Wire strippers – buy one as shown: it clamps wire then strips. It’s safer than using a knife.($20)

•Retractable knife ($2), Side cutting pliers ($14), crocodile leads ($6).

•The above items can be bought on eBay™ or similar supplier.

Fault finding items:

•Resistors fitted with 3 metre lead + crocodile clip each end (to suit):

–  12V LEDs – 2 of 1200 Ω 1/2W connected in parallel (= 600Ω or Ohms)

–  24V LEDs – 1 of 820 Ω 1W

–  120V LEDs – 1 of 5,000 Ω 10W

–  120V bulbs – 3 of 220 Ω 10W connected in series (= 660Ω)

–You will have to make these – see next slide for an example.

Note: resistor wattage was made oversize to reduce its temperature. Ensure live parts are insulated as shown.
