Help - Lighting Question - "bulbs"

I am new to jewelry photography - I purchased a
Impact Two-Light Digital Light Shed Kit - 15 x 15"
it came with two 2x Daylight Balanced 250W Bulbs
but they burned out within hours!! - does anyone have any suggestion of bulbs that will last longer???
also is 250W enough or should I be using brighter? help!

The B&H page says these lamps are BCA bulbs. BCA are special photoflood bulbs for photography, controlled color (4800K, near daylight), but have a short life, about 12 hours. They are sort of low voltage bulbs operated at regular voltage to make them bright, but short lived. You don't turn them on except for during actual use.

For example, see
Sylvania / Osram BCA Lamp (250W/120V) 11655 B&H Photo Video

There are others, like ECA, 3200K (incandescent) and 20 hours life.


Or, you can use any type of bulb that suits you. Regular bulbs will have regular life.

You really don't need bright. Jewelry is not going to move, so you can use any slow shutter speed you wish. With a slow shutter speed, it is good practice to use the self timer, to get your finger off of the shutter button a couple of seconds before shutter, to let your fingers vibrations fade away. Or a shutter release cord.

If you shoot RAW, you can get the White Balance right in the post production. As suggested use normal LED bulbs and use longer shutter speeds.

thanks guys!
