Four assorted, junk studio halogen light bulbs: JP100V500WB/G by Panasonic, and others. I don't know how much they've been used. I don't have the equipment to test if they light up. Please understand this before purchasing. I've included detailed images, so please make your own assessment. ① Panasonic JP100V500WB/G ② National JP100V500WB/G ③ Fuji FCD 100V500WD/L 7J ④ BS7.5-30 100V750W RDSR-I ① and ④ look to be in pretty good condition. ② has what appears to be rust. ③ has one side that's blackened and cloudy inside the glass. For those who know how to use them, please consider purchasing. Panasonic national Ushio Studio lighting live HOH70100100
