Illumicare 300W Multi-Tap Transformer

300W Multi-Tap Toroidal Core Transformer with Built-in Timer. Whether you need a short wire run to light a few clustered fixtures, or a longer wire run to power enough fixtures to illuminate a 200 foot driveway, our transformers offer voltage taps ranging from 12 to 15 volts. Illumicare’s multiple voltage taps reduce the risk of installing wire runs that lower the light output, change the color temperature, shorten the lamp life, or even burn lamps too hot.
