This 24V ACR 6003 bulb is a perfect replacement for your RCL100 spotlight. Each spotlight needs two bulbs, and they're sold separately. It's recommended to replace both bulbs simultaneously for optimal lighting.

Using this bulb is easy. Just remove the old bulbs from your RCL100 spotlight and insert the new ACR 6003 bulbs. Remember, each spotlight requires two bulbs. When replacing, make sure to turn off the power to avoid any electric shock. It's a good idea to replace both bulbs at the same time to ensure uniform lighting. To keep the bulbs working well, keep the spotlight clean and avoid touching the bulbs with bare hands as the oils can reduce their lifespan.
