      A:

      This 250 watt metal halide lamp is intended for use in areas that require high lumen output such as gymnasiums, high-ceiling retail stores, parking lots, etc. This lamp is not a very good choice as a photography light source due to its low CRI (color rendering index) of 65. A lamp with a CRI below 80 will cause the colors of lighted objects to appear muted and not as vibrant as they would be under a higher CRI light source. If you need lighting for a studio or location shoot you should contact a Bulbs.com Lighting Specialist at (888) 455-2800. Let the rep know the type of fixture including socket style you intend to use. Any added information you can provide regarding your lighting requirement will be very useful in identify the best light source for your situation.
