Great to know mercury lighting still isn`t completely dead, not just yet anyway.
You can still get
mercury Nordex Astra lanterns too. I bought one of those from that site a couple of years ago, purely for the novelty of still being able to buy a brand new mercury lantern, while all around the country they are disappearing fast. Even the new motorway gantry signs along the M4 near here seem to be lit with warm-white ceramic metal-halide lamps now (could be Cosmo lamps even, I find it almost impossible to tell). It looks quite strange and doesn`t exactly compliment the blue colour of the signs, but I guess that`s the future.
I installed a mercury wall light on the outside of our office earlier this year, one of those brown bulkheads with the in-built photocell. And the three low-bays inside all burn 250 watt mercury lamps. Used to be SON, couldn`t bear it. They aren`t used all that frequently so should last for years and years.
