How to Choose Energy Saving Light Bulbs..??

Morrisons are selling Philips 60W & 100W equivalents for 49p a go IIRC.

Thanks - is that for energy saving light bulbs?

I thought they were a lot more expensive than that...

Yes they are energy saving - from memory the 60W equivalent are around

Use a search engine, on this group and more widely, instead of expecting to be spoon-fed. They were discussed a few days ago.

fwiw I had a couple of philps and didnt like them, Osram I've had good results with. Equivalent power is at best 4x, so ignore the wattage equivalent nonsense on the pack.

And stay well away from cheapie =A31 jobs. Whatevcer you use will save you the cost of the bulb several times over, so its ok to get 1 of each of a few brands if youre new to them. Some are excellent, some so-so, some borderline, and the =A31 halophosphate jobs are dire.

Thanks for the info.

Sorry dear...PMT...?

Personally, I quite like the Morrisons 49p philps ones.

I've installed 20 as garage lights, on a wire, along the middle of a

Nice try. Now get off your fat backside and do some work for yourself, instead of expecting others to do it for you.

Baby birds sit on their backsides, squawking and expecting mummy or daddy bird to stuff worms down their throat.

you've got a 20m garage? That would explain a lot, all the things you get upto :)

But I still havent figured out why you were running a several foot long fl tube at 1uA!

Err, typo. Well, thinko. It's more like 10.

To measure the V/I curve of the discharge. It was quite pretty in the dark, a moon-like glow.

That is a good sized garage.

How do these things cope in the cold?

Ditto Morrisons here. 99p each but on a bogof offer. Philips brand. As near instant start as any CFL lamps I've used, although usual few minute warm up to full brightness.

Indeed - I meant 12*4

A bit slow to warm up. But then, because they were so cheap, I've put in about double the wattage that I really 'need', so to get up to half 'normal' brightness isn't bad at all. (based on one test with one inthe fridge)

That's *still* a good-sized garage!

So they will start OK, unlike (seemingly) my 4' or 5' tubes?

That's nice & thorough. What about sub-zero, I wonder?

I've stuck one in the freezer. Will post in an hour.

First bulb - 1/2 hour in freezer. Starts instantly, quite dim for first 10 seconds, then it rapidly warms up towards normal brightness. I would estimate that a 20W bulb is equivalent to the initial output of a 11W bulb at room temperature 15 seconds in.

I've got the blighters all over the house. Only ever had to return one 'cos it didn't work at all. Watch out for some of the real cheapies - they can produce a bluish light that actually induced nausea.

Great for middle of the night swap-outs if someone in the house is likely to get a hangover...

That's very useful, thanks for the results!
