Re: Compact Fluorescent Lamps - A Radioactive Surprise

Your right. One of the youtube videos I came across said the lighting ban for what's classed as "inefficient" lighting was raised by the lighting companies themselves surprisingly not the environmentalists. The likes of Sylvania, GE and Philips still get their £20 a lamp though the cost be...

Re: 70s Street lighting Vid

Nahh I doubt we'll marvel at LED street lighting. Mind you I seemed to remember the Flouros weren't great even though the were high density installed. What I find funny is there people used common sense and drove carefully, these days its a Blame culture and "It weren't my fault". If i rem...

Re: Compact Fluorescent Lamps - A Radioactive Surprise

I'm thinking this is why the US is banning them. This week I found a CFL takes about 2Kw of energy to make and 1-2Kw to environmentally recycle it, that's without the energy to make the components to go into it. I recon your looking towards 5kW + energy use not forgetting the 20% energy losses in th...

Re: The End Of The CFL

You mean you've forgotten, LED is the answer to everything. I remember many US homes didn't the like "Pig Tail" lamps. There was a huge row when they came in especially with the 15 minute evacuation routine if one broke as well as all the lamps being made in China rather than the US. What ...

Philips FRS / MA

I heard about this before but not seen one yet. Looking at the video it appears in Europe the Philips MA is fitted with a different gear tray and use one or sometimes 2 PLs instead of the SOX we have in the UK.

70s Street lighting Vid

This looks to be a top deck of a London bus, but showing some spectacular views including the large quantity of fluorescent and SOX street lighting with the absence of SON and old Tin Plessey traffic lights.

Note how shocking the driving standard was!

Its been a quiet morning at work so been watching Clive's channel on youtube.

Re: The New Super Effecient Incandescent?

You beat me to it Tom. I heard this promising news this morning on the radio. It makes sense using the same IR technology reflector technology they use on the likes of SOX to reflect IR heat back into the lamp. It makes sence if less heat is escaping and more being bounced back into the lamp the fil...

Re: T4?

I wouldn't say T4 has any benfits over T5 whatsoever. As Tom says T4 tubes come in random wattages and lengths with absolutely no standardisation between manufacturers making replacement tubes a nightmare. Generally though the crappy fittings fail before the tube does so finding a replacement tubes...

Bloody crap LED lamps.

Re: Philips’ 200 lumens-per-watt prototype LED lamp is the world’s most efficient

Sadly they'll never happen, well unless they can produce a LED lamp for next to nothing. Its a bit of a double edge sword, If we want products produced ethically then we need to pay double of triple the amount. As we are loured into the world of cheap consumerism we turn a blind eye to ethical rites...

Great to see them but for me even better to see MV still used large scale.

Its one of the advantages of non-EU membership, If you want to use lighting that is banned in the EU then fill your boots. :woohoo

lol - good point there Paul... But alas there is no Mercury involved so that's absolutely massive for the environmental argument. I'm guessing I've been running LED in the house for about 3 years.
