Bulbs can explode unexpectedly, so it is best to have a screen on the front of your lights. Do not use the bulbs too long, the color temperature will decline and your pictures will not turn out properly colored. Your finger oil will cause premature failure. Be sure your lamps are shielded. Occasionally lamps do explode, sending liquid hot molten glass and metal fragments all over the place.
Lamps come in a variety of sizes and shapes.
Do not exceed the specifications of the fixture you are using. Use heavy duty extension cords. The Lowel lights that we used, DP and Totalights, did not produce any irregularities on the digital image that we could detect with the naked eye. But Dedolights, of the kind operating from their own transformer, did produce appreciable defects in the digital images, though not every lamp and not every time. Electric fans, copiers, or any motor, even if far away in the same building, produced distortions of the digital image.
