    Professionally Researched. (What's this?)

    On One Hand: Light of your life

    Many consumers are switching to metal halide bulbs, which can last nearly ten times longer than traditional incandescent lights. That means fewer times you have to climb a ladder and risk injury. Metal halide bulbs also emit a more natural light, which can provide higher acuity in low-visibility situations.

    On the Other: Don't get too close

    Some users have reported temporary vision distortion from exposure to short bursts of metal halide bulbs at a very close range. This is known as Photokeratitis, or snow blindness, and can result from unprotected exposure to ultraviolet light. Bulbs using a quartz arc tube have also been known to be susceptible to explosion at the end of their lifespan as corrosion of quartz breaks down the bulb.

    Bottom Line

    Metal Halide lights are safe when correctly installed and monitored. These power-saving bulbs last much longer than traditional lights and can be a safe alternative to incandescents. Always remember to power down a metal halide light for at least 15 minutes a week and protect vulnerable bulbs with a quartz shroud.
