stillwave Posted June 15, 2009 Share Posted June 15, 2009 Additional information re the coming ban on incandescent lamps, received in an email from a major lamp suppliers. 150 watt and 200 watt GLS lamps are now banned, in any finish, (suitable alternatives are halogen or compactflourescent) All common types of pearl/opal/otherwise non clear lamps to banned from the end of this year, including GLS, candle, golf ball.(suitable alternatives are compact flourescents) Has anyone else got a reference to this i.e. Gov papers, google turned up http://www.ableduk.com/ but this seems to be a 'household' orientated website. does anyone know of alternative lamps for 230V/240V DC secondary BC fittings?

rooftop Posted June 15, 2009 Share Posted June 15, 2009 I've also been told from two sources (one a distributor, other elec. engineer) that everything down to 15W GLS are being made illegal to import into / manufacture in the EU by the end of the year.

musht Posted June 15, 2009 Share Posted June 15, 2009 Calm down guys, sure distributors would like you to be looking at retrofitting everything in sight in the next 6 months...in fact mebbe this is a rumour should be encouraging. Reality being that 2017 is target to get rid of al GLS style lamps in all the sizes and colours and pearls etc. It is reliant on acceptable alternatives being found and specialist lamps being exempted for long after others will dissapear, specialist in this context being a fairly wide definition. Havent actually seen IR reflective K series lamps on the shelfs in 230V. Now if you try and raise any of these points with the Green Party...........er........good luck Link to comment Share on other sites More sharing options...
Andrew C Posted June 16, 2009 Share Posted June 16, 2009 I suspect that the difficulties will start much sooner than that; when the general public stop buying 100w GLS, the manufacturers will stop making them. This is regardless of our need to use them in house-lights or whatever. Equally, 25w golf balls fr dressing rooms (which is probably a small market already) will disappear.

Nick S Posted June 16, 2009 Share Posted June 16, 2009 Already there's a big sign in the window of my local hardware store that says "Yes, we still have 100W bulbs!". Link to comment Share on other sites More sharing options...

Grahame Posted June 16, 2009 Share Posted June 16, 2009 There is an excellent article by Kevan Shaw in the current issue of the ALD magazine Focus, detailing all the arguments against CFLs, and it's scary reading in parts. It's mostly summarised on savethebulb.org, and in this PDF of Kevan's presentation given to the Joined Up Lighting Seminar in London on 17 October 2007 covering the arguments regarding the problems created by the proposed ban on incandescent lamps. Essential reading! Link to comment Share on other sites More sharing options...
adam2 Posted June 17, 2009 Share Posted June 17, 2009 I've also been told from two sources (one a distributor, other elec. engineer) that everything down to 15W GLS are being made illegal to import into / manufacture in the EU by the end of the year. I think that they are mistaken, AFAIK it is only the opal and pearl lamps, and higher power lamps that are being banned from the end of this year.Clear lamps in 75 watt and up will still be available, but only for a limited time. A concurrent post has been automatically merged from this point on.

Havent actually seen IR reflective K series lamps on the shelfs in 230V. Now if you try and raise any of these points with the Green Party...........er........good luck I believe that 2017 is indeed the target date for abolition of virtually all GLS and similar lamps. however many types are being banned long before then.I have seen linear halogen lamps in IRR on retail sale, and these may soon be the only types available. A concurrent post has been automatically merged from this point on. Has anyone else got a reference to this i.e. Gov papers, google turned up http://www.ableduk.com/ but this seems to be a 'household' orientated website. does anyone know of alternative lamps for 230V/240V DC secondary BC fittings? I received details from a major supplier, not certain if OK to post here or not. Almost all modern types of mains voltage CFL can be used on DC supplies as well as AC.The light output will often be less on DC since about 340 volts DC is needed for full output.This should be no problem for 240 volt DC secondary lighting since the much higher efficiency of CFLs would allow higher output lamps to be used.For example on a 240 volt battery system I would replace 25 watt gls lamps not with 5 watt CFLs but with 9 or 11 watt.The reduced output of the 9/11 watt CFL on DC would still be greater than the 25 watt GLS previosly used.I know of one installation where the 240 volt battery required replacement, and was replaced with one of 252 volts, so as to give better light from CFLs.

Tomo Posted June 18, 2009 Share Posted June 18, 2009 Almost all modern types of mains voltage CFL can be used on DC supplies as well as AC.I hesitate to say this, but they are almost certainly wrong, and dangerously so.All 230VAC CFLs are designed assuming an AC supply - the clue is on the rating plate!The one I have on my desk says "230-240V ~50-60Hz" It makes no mention whatsoever of DC operation, and therefore it would be foolish to try to run it in such a manner. The majority of 'off-the-shelf' units absolutely require an AC supply as they use capacitive and inductive components which will not work in DC conditions. These would fail dangerously if given a DC supply, as the inductor will become a short circuit within moments. CFLs provided by that particular company may have electronic ballasts designed for both DC and AC operation, but they would be the exception, not the rule.

dbuckley Posted June 19, 2009 Share Posted June 19, 2009 Oooh... discrete components. I thought the world+dog had migrated to some chip made by IR for this purpose. But yeah, I'd hazard that pretty much any modern non-dimmable CFL would run on DC, the days of chokes in CFLs is pretty much gone the way of the dodo.

adam2 Posted June 19, 2009 Share Posted June 19, 2009 Virtually all modern compact flourescent lamps will work fine on DC. The incoming supply is first passed through a bridge rectifier, and then smoothed by means of a capacitor, the rest of the circuit only sees DC from this rectifier and capacitor, and therefore does not "know" if the supply is AC or DC. When powered from an AC supply, the capacitor charges up to nearly the peak value of the AC mains, about 340 volts.If connected to a 240 volt battery, then the capacitor can only charge up to about 240 volts, not 340, hence the reduced light output on DC. The Philips lighting catalogue refers to operating compact flourescent lamps on DC. It would be potentialy dangerous to connect a CFL with a built in magnetic ballast to a DC supply, these however have not been manufactured for at least 15 years, which is why I stated that only MODERN CFLs should be used on DC. AFAIK the only mass produced magnetic ballast CFLs were the early versions of the Philips SL lamps, these went out of production about 15 years ago, and were never very popular.(Phillips still make an SL lamp, but it now has an electronic ballast) Link to comment Share on other sites More sharing options...

OK, I've replaced eight out of the ten that I insisted would save us money (much scepticism there was too!) over the last year or so, but there are still two running!

The Yellow Transit Posted June 19, 2009 Share Posted June 19, 2009 I have seen the replacment lamps for gls style lamps and they are halogen capsule lamps within the old shape envelopes , so the 60w lamp becomes a 42 W giving a saving of 30% . This infomation is displayed at Wilts wholesalers. The price is high at the moment but will probably drop when theres no choice conventional style halogens Link to comment Share on other sites More sharing options...
rooftop Posted June 19, 2009 Share Posted June 19, 2009 Indeed - Osram are now manufacturing these as direct replacements for pearl GLS... I have been sent a 70W sample which is indeed very bright - easily equivalent to a tungsten 100W. Trouble is, they're only going down as low as equivalent of 40W tungsten for the moment Link to comment Share on other sites More sharing options...
