    New lamps

    Hope this is the appropriate section to post this?

    Here in the UK by the year 2011 the goverment are phaseing out most types of tungsten lamps and replacing them with energy saving lamps. I don't know how this will effect enlargers and safelights that use tungsten lamps.

    These energy saving lamps are brighter watt for watt then normal tungsten lamps, for example a 9 watt energy saver is approx. to a 40 watt tungsten lamp. Also they are at the moment physically larger then standard tungsten lamps.

    My enlarger uses halogen lamps so as yet this will not be a problem, my concern is with the small 15 watt pygmy lamps I use in my red safelights. If these are discontinued the new lamps will be too bright and physically too big to fit the lamp housing. In any case these new lamps are not suitable at present for use in enclosed fixtures.

    I would be most interested if anyone can provide more information and if a similar scheme is in place in other corners of the globe.

    Always in the dark,
    Trevor.

    Check but I think the small CFCs can fit an enclosed housing.

    It shouldn't be too hard to find the small bulbs. What do fridges use ? Range hoods?

    Worse case an LED safelight could be rigged up.

    You'd think that as pygmy lamps are 15/25 watts only, then the Govt would have the good sense to realise that these are already on a par with energy saving lamps but there's the snag - believing that Govt and good sense on such matters go together. We'll save planet by eliminating pygmy bulbs and building extra runways all over Britain.

    Somebody said that most of the Govt ministers can trace their ancestry back to deck chair arrangers on the Titanic. Scurrilous rumours - probably.

    Sorry not very helpful but "By God I needed that" as Ken Dodd used to say after having a quick burst on his banjo.

    Trevor, this doesn't really answer your question but I have been very satisfied by replacing my 15W-type safelight with an amber LED from Optiled (no connection), webpage http://www.optiled.com/products_lamps.php?prod_id=21. They can be had in bayonet or screw fittings which work with standard UK sockets, and they are brighter than most tungsten-based devices. I suspect that they have a narrower spectral spread, so should in this respect be safer too!

    If your are that worried that suitable replacements will not be available why not buy a six pack now; should last a life time, or two.

    Somebody from the govt or similar public position said on BBC Radio 4 this morning that only standard domestic bulbs are being phased out, and specialised incandescent lamps will continue. Also on the news today there is growing concern about the health risks associated with CFLs - they can cause skin problems for some people. http://news.bbc.co.uk/1/hi/uk/7172662.stm

    As Dave says, buy a six pack anyway. In my 20-odd years of printing I can only remember one of those bulbs blowing!

    By 2011 LED technology should have come on far enough that CFLs themselves will probably be obsolete, and LED safelights are available now.
    Regards,

    CFL can be regarded as short term technology, to be superseded in this decade. So the arguments are moot.

    Agreed, Dave. LED replacements for some types of incandescent are already available, for example 20W halogen MR16 lamps and more will surely follow.

    Please excuse the darn commercial at the beginning, the Neurosuergon is brilliant, he also suffers from migraines.
    CFL's give me headaches, and I get migraines too, it doesn't take a million euro, pound, or dollar study to tell me that the flicker rate caused headaches.

    Are LED getting cheaper? Cheap enough to build a nice large enlarger head?
