Just bought a new shade for the pendant light fitting in the front room - 60w only. Popped in a 60w bulb and it's like stumbling around in twilight rolleyes

It would seem that you can't really get 100w lampshades any more as the powers that be have decided that we aren't allowed 100w lamps.

So, I'm thinking I'll get a 25w low energy lamp - supposedly the equivalent light output to a 125w lamp, but I understand it's probably closer to a 100w.

Just wanted to check with the PH massive - will this be OK in a 60w shade? It's all down to heat output, not power consumption, so I guess it should be OK.

Thoughts?

Yes it is down to heat output, and yes 25w will not set it on fire. CFLs are evil and I hate the unthinking morons who forced this insane legislation upon us. Once upon a time, we saved energy by switching lights off when we weren't in the room; now we are compelled to leave the bloody things on all the time because the crappy CFLs take a dog's age to warm up and give off more lighting power than a single sexually exhausted glowworm.

That's cobblers. We have these little curly type flouro tube 'eco' bulbs over in the backwaters of the Philippines, and I was amazed at just how bright they are, and it is instant, no warming up, and minimal heat.

Maybe ten years ago they were crap, but they are a different animal nowadays.

I shall probably be using them in my workshop, when it is finished, because they are just so small, so bright and so cheap.

I find the cheapo ones (10p each subsidised jobs) take a while to get going but Ok for outside lights etc. Decent Philips faststart ones cost about £4 each for 110w equivalent & work very well, look nice too!

+1 & the energy savings ARE huge over a year.

Energy saving lightbulbs? You'll expect me to be carrying the hideous heavy-metal-laden dim overpriced excresences in a hessian sack with 'ECO' written on it. Along with my water-based fence stain that doesn't work and water-based see-through Tipp-Ex. Pah.

That's a bit harsh, I save electricity by replacing all the 100w bulbs with 4 x 50w GU10 downlighters that are so popular now wink

Indeed; whoever did the cost/benefit analysis(if they bothered at all) didn't take cognisance of the fact they contain mercury and berilium and the stupid general public will just toss them in the bin so they end up contaminating landfill.

And do they really save you money? It's balls that the waste heat from incandescents is waste anyway; in the UK most houses have a boiler to provide heat, where do you imagine the heat from the lamps goes?

Dont get me started on Water based fence stain, wheres the fun of that? painting a fence is a dull job getting high off the fumes is the best bit!

yes This far from the equator we heat our homes for half the year. If my lightbulbs could waste enough heat my radiators would trip off. And I'm pretty sure they use more power than a lightbulb.

Ha, yet another benefit of low heat eco bulbs. biggrin

Average daytime temps where I live are about 30C. I need more heat in my workshop like I need a hole in the head.tongue out

I agree. Hateful things.

If anyone can send me a link to these super-duper, instant light-up bulbs I'd be most grateful.

A light bulb that starts up instantly? Blimey, who'd have thought it!

Not a link, but a vendor: They sell them in SM Megamall, Angeles City, Pampanga, Philippines, and also in Wilcon Depot, San Fernando.


Probably like cold water detergents; they had it in the third world for decades before releasing it in the UK. It is all about profit and power, politics and big business.

CFL's are at their most efficient if they are turned on for longer periods, and not on and off.

Exactly like normal 'old fashioned' fluorescent tubes then?

That's because it's already warm where you are!

Mate of mine says the outside ones at his house in Finland won't even come on when it's very cold.

So leaving them on longer saves energy? I'm phoning Dragons Den. biggrin

It's a pain - a lot of energy saving bulbs take up to a minute to warm up enough to give out the light you need, which makes flicking the lights on quickly to find something, quite pointless.

I have some 'candle' shaped low wattage bulbs which seem to warm up instantly though - I don't know if it's more to do with the design though, they're not the usual coiled fluorescent tube that most are.
