100w lamp.

[Dave Plowman (News)]

Have only one room with what was once the traditional way of lighting - a

100 watt single central light. And noticed there seems to be no modern equivalent commonly available in my local large supermarket.

So have the elderly, who would be most likely still to need this, suddenly have better vision than once?

Biggest I could find in BC was a 60 watt equivalent. And LEDHut no better.

Did find an 105watt halogen. Which from previous experience have a short life. Not the 1000 hours you'd expect from a 100w GLS type.

[Martin Brown]

You won't find 100W equivalent in supermarkets. They are available. I prefer LED warm white with Samsung or Cree LEDs. eg

Nominally 1500Lm. I might get one for my mum as she is always complaining that the new light is too dim in her living room.

The difference between 75W and 100W isn't all that great. The eye has a logarithmic sensitivity.

You can also get CFLs upto about 25W. Never been impressed with them.

[Jimbo /p]

thought you could still get 100w bulbs for "industrial use"...won't bother me though.. I stocked up with 100 150 and 200w bulbs in bulk before the ban ...

Jimbo /p put finger to keyboard:

You can get 'rough service' 100w GLS bulbs. Look in pound shops, 'Savers' etc.

what wrong with a fitting with multiple holders. Not being particularly green-minded, I have 5 upward facing 60w dimmable tungsten ones, probably worth 3000 lumens, plus they keep the room warm.

[Martin Brown]

And also at Amazon. I sometimes need 150W rough service lamps.

[Charles Hope]

It depends how hot they get. We use them in our Village Hall. We don't have life problems.

The 12W LED lamps at Toolstation do a fairly good impersonation of a

100W bulb IME. Not cheap mind - about 8 quid last time I bought one (although they do claim 35000 hours of life).

Charles Hope put finger to keyboard:

Vibration killed mine. Halogen lamps in downstairs fittings (in a two- storey house) sometimes only lasted a month.

[Dave Plowman (News)]

A pretty standard pendant fitting a couple of feed long. Plain lampshade with a large hole in the middle. So should run as cool as anywhere. ISTR it had a claimed life of 2000 hours. Which with this application would be many years.

I have a 150W-equivalent (25W CFL) in my office and we have 100W-equivalents (20W) in the bedrooms and on the landing. All daylight rather than incandescent or warm white, because that's what we prefer, but I'm sure inc or WW are available. Ours are branded Eurozone and we bought them on Amazon.

The only slight disadvantage with daylight bulbs is that it is harder to tell that you've left the light on during the day (my office has fairly small windows) because the light from the bulb really does look like daylight, whereas the orange tint of incandescent bulbs makes it a bit more obvious that the interior light is not just sunlight shining through the window. I've gone out several times and got back in the evening to see the light still on :-(

I prefer CFLs over LEDs, mainly because the lit surface of a CFL is larger so you don't get sharp, stark shadows from the point source of the LED cluster.

[Martin Brown]

It isn't heat buildup that kills them (unlike CFLs and LED bulbs) although it may set fire to things. The filament already runs very hot.

It is vibration of the filament whilst hot and/or power surges that does for them. Haven't had any problems here since they rewired the main power line into the village. Prior to that it would arc and spark flickering horribly every time there was a storm taking out lights.

Most annoying were classic spotlight failures where the internal fuse would invariably take down the lighting circuit ELCB as well. They are all now rpelaced with Phillips LED spotlights (non dimming ones I bought up remaindered) which are if anything too well collimated.

[Martin Brown]

You prefer a light that takes five minutes to reach full brightness?

LED lamps do come with diffusers unless you buy cheap and nasty corn on the cob types or engineered acrylic cone ones for chandeliers. The latter are surprisingly convincing in the right sort of fixture.

[ChrisK]

Asda have (had?) an 18w LED lamp which works well as a 100W substitute. A bit expensive (£14.99) but were reduced to £10 or so recently. I've been using two in the main living room since January with no problems though I'd imagine closed fittings would be a problem.

Colour temperature is also better than the two 23w CFLs they replaced.

You can buy 135W CFLs (true wattage not equivalent), they are about £10 each and last about 8000 hrs.

Look for photoflood replacements.

[NY]

The ones I buy seem to reach an acceptable brightness almost instantaneously. They may increase a little bit further over the next few minutes but there isn't the experience of turning on a light and finding the room is so dimly-lit that you can't see anything for ages.

It's a shame that "time to reach x%" of full brightness (for some agreed value of x) isn't a parameter that manufacturers are required to publicise on all sales literature to help you choose fast-start ones.

I find that LED lights are a bit stark. Also, the conical-beam GU10 downlighter spot lamps (eg for use in a bathroom ceiling or in a multi-head kitchen light) tend to have a much narrower beam with a sharper cutoff than the tungsten equivalent. They are fine in a kitchen or a bathroom, but not in a room where you want to read or want a slightly more restful light.

[harry]

I have several of these. They seem to be as bright as a 100w lamp.

You are looking in the wrong shop.

Instead of looking in supermarkets (who voluntarily gave up selling 100W lamps) you need a shop where two streets meet to form a right angle:-)
