"Long Shipping Cover" (a.k.a Bulb Protector) as used in the Alien Bees / White Lightning and UltraZap flashes.
Why do we have these, you might ask...
We manufacture a machine vision system that incorporates multiple Alien Bees strobes into its illumination system.
The strobes go into custom enclosures, with custom wiring and mounting, so we strip the unneeded factory accessories when we receive them. From time to time we put these items up for sale.
See our other auctions; we have reflectors, power cords, and sync cords, and occasionally, modeling lamps and flash tubes as well.
We offer combined shipping on multiple units. Stock up and save!
To take advantage of this, *request an invoice before paying*...
If that doesn't work, go ahead anyway, and I'll rebate you the excess shipping.
