250-watt MB/U lamp on Ebay, a bargin for someoneI think this seller must have a job lot of these, but is selling them one at a time.
Seeing that someone had bid on the one Claire had highlighted, I thought it had been an opportunity missed, as they are certainly rare, not on sale any more (as far as I searched), and I wasn't born early enough to see these in action (they are effectively the MBF/U lamp before they started adding the phosphor coating to improve the colour rendering).
Having said that, I still thought it would be nice to own one - and fire it up in the GEC Z8430CM once in a while - but I still didn't fancy an expensive bidding war with the other bidder. But as soon as the one Claire spotted had disappeared, another one came on sale from the same seller at the same price, so I bidded on it, was thankfully the only bidder, and won it for £5 plus £4 postage. And as soon as bidding ended on my one,
another one appeared! The auction for this one ends on Thursday night.
My GEC Z8430CM from Harrison Lighting now has three bulbs - a 250w MBF/U, a 250w MB/U and a 210w internally ignited SON retrofit, but it still has no bowl. Thank you to Claire for finding these rare bulbs for sale!
