Telephone & VP Signalers
When using a lamp that plugs into a signaler or transmitter, there are several types to choose from.
- Instant-On CFL (compact fluorescent lightbulbs): The key is the instant-on feature. They have a life span about 10x longer than incandescent bulbs, and use less energy.
- Halogen: Provides a warmer light than CFLs but can cost up to 2x more. As incandescent bulbs are phased out, halogen bulbs should drop in price.
- LED: Works well but can be quite expensive, averaging about $18/bulb or more.
- Incandescent: Can last up to 5 years or more. Stock up while they're still available.
