how to change bulb in commercial landscape light
If your landscape lights seem to burn out faster than ever before, it may not be the fault of cheaper materials or shoddy workmanship; the fault may be in the method you use to change the bulb. Many modern landscape lights use halogen bulbs, both for inexpensive use and for the brighter light they give. If you touch a halogen bulb with your bare hands, the oils from your skin can transfer to the bulb. These oils will heat up and burn on the surface of the bulb, creating a thin spot in the glass that will cause it to burn through much more quickly than usual. Take precautions when changing halogen bulbs, and your landscape lights should last through the season.
