HP 2100 bulbs

Greetings folks. I'm on a mission to get some replacement bulbs for my 2100A/S machines. The official part is 2140-0364 (38 of them per machine). Google appears to indicate that an identical replacement is CM7361-200. One of my old parts donor 2100's has both OL-783BP and OL-783BPC, but I don't know if those are completely identical and the previous owner may have just put something "close" in them instead (particularly important is estimated life, the 2140-0364 are around 10,000 hours I think, other replacement parts appear to be a lot less life-hours). I'm not looking to replace just a few bulbs, as I have a few spares on hand already. I'm looking to buy around 50 or 100 to just have inventory, and in case I decide to fully restore the two 2100's that are currently donor machines and get them fully running. Has anyone already found a good source/price for these? Given the number of bulbs per machine, cheaper is better :) I may have to go to one of those bulk purchase parts places, in which case I'd probably need an order of 1000 or so. If I have to go that route, anyone with 2100's want spare bulb sets and willing to go in with me on it? Just as an FYI for HP bulb related stuff... I just purchased 30 bulbs for my 7970E tape drive status lights. They were $0.28 each bulb (sold in 10 packs for $2.81). Those were: Eiko - 382 mini indicator lamp - 14 volt - 0.08 amp - T1.75 bulb - midget flanged base I just put in an order for the HP 2940 rack (these are the older off-grey/greenish racks) power switch bulbs. those were: GE & Eiko - 1819 sc1 - 28 volt - 40ma - T3.25, miniature bayonet (BA9s) Best, J
