LED Lighting Lamp?

Posted by: George J on 18 October 2014

I am an enthusiast of everything efficient at what is supposed to do. A lighting lamp should make light and a heater should heat.

 

Of course an electric heater is 100 per cent efficient in the house as it converts all the energy metered to heat, but light bulbs of the incandescent variety make more heat than light, while the CFL type lamps make more light than heat, but contain Mercury in the light emitter ..  and are a horrible sort of bulb that is hard to read by apart from taking ages to warm up to full output. LED lamps are almost twice as efficient as CFL and come on immediately.

 

I have just bought a 9 Watt LED lamp to go in place of a CFL lamp for my main light. It claims an equavalalent light output of a 60 Watt incandescent lamp. In fact it is probably slightly brighter. It is far nicer than the CFL that also claims to replace a 60 Watt incandescent ...

 

Am I at the bleeding edge? I have a good eight light bulbs to convert, and at more than a fiver apiece, this is not cheap, but all sizes and fitting-types are now made by Philips. All will be converted to LED over the next twelve months, but none will yield such a saving as my main lamp, as all the others run much shorter times ...

I was starting to get paranoia until I twigged that the PLA in question was (presumably) a powerline adapter, and the 2.5 million strong Peoples Liberation Army hadn't just invaded Suffolk!

I know Suffolk's quite big, but that 'd be standing room only (and I wonder what the Chinese would make of the pink cottages).

 

And just because your paranoid, it doesn't mean they're not out to get you.

Update.

 

I ordered the five Philips LED lamps off Amazon to eliminate the remaining incandescents. 6 Watt LEDS to replace 40 Watt incandescents ...

 

The price was the same as Wykes without the promotion, but the new Wykes stock will not be on promotion in any case. I'd just like to finish the conversion. I shall keep the old bulbs to replace, should I have to move ...

Do you mean Wickes , George? Or do you have a local shop called Wykes?

The large chain hardware store!

 

Which ever speaking is correct!

 

Sorry about that!

Thanks for clearing that up, we only have a Wickes bathroom store around here.

Enthused I bought a LED to replace the lamp in the living room.

With the last lamps changed all is now converted to Philips LEDs except my bedroom and that will need my electrician friend to instal three wall mounted units to take standard fitment lamps of the LED sort. He is ready for when I get the lamp holders. No way would I try to fit such things. I could do it, but I would never forgive myself for starting a fire!

 

That is the November project.

 

I also secondary-glazed the single glazed windows, and the result is it is toasty without any heating this evening. Storm guard film glazing. I did one window last year, but with experience I used all the film and did the glazing on both doors and the front window successfully this time ...

 

Ready for a cold winter as it goes..

Thanks for this topic and discussion.  I bought a clamp LED for my turntable and it is very bright.  Now I'm in a remodel of a prefab house in Palm Springs.  The electrician and others said go all LED, I'm a bit nervous about that.  He showed me 2 pics of a very nice home he did and said don't worry.  I'm sure it'll take some getting used to. He's going to be using an LED strip lighting under  counters and a couple other places where a glow is needed. Good thing about recessed ceiling lights is no need for lots of lamps and cords to wall sockets. It'll be a very open living plan.

 

One of the great things about this place is a dedicated electrics for living room and sound system, probably the 100 and DAC.  I won't permanently move out with my big system here for 5+ years. Can't imagine moving my vinyl to the desert but the AC will never let it get hot.  Sure has been a whirlwind of contractors and many different decisions and changing ideas.

 

My apt in LA I have Halogen track lighting, always keep them dimmed because I like the amber glow.  I must be part werewolf as I hate walking in a room and having the bright light flash on, or is that vampire? Many nights I never turn lights on because I know the 650 square feet so well and where I keep that whisky.  Why have bright lights listening to gorgeous music? I do have a nice halogen reading lamp by my couch, when that transformer gives out I'll get an LED.

I have now completely switched to LED replacement lamps that fit into the conventional bayonet or screw fitting designed for incandescents. 

 

I like the light that comes. It is very white, and thus good for reading. My central light in the living room is a 40 Watt equivalent, but the quality of light is actually more like a 60 Watt incandescent in my experience. I have a lovely table lamp [once my Norwegian grandmother's] that I use when not needing to read, and because it has a nice bleached Hessian shade this does cast a very pleasant warmth of light into the room for music or watching DVDs ....

 

They come on instantly, and will; save money over time compared to incandescent lamps. They run very cool, and so I am happy that the kitchen and bathroom now have three 40 Watt equivalents in each, yet using less than half the replaced lamps, as I only had one incandescent fitted in each room to save on electricity.

 

You could call me a skin-flint!

Its amazing the LED options around these days,  its gone from a limited number of "looks like" type lamps to stuff that is far different to any of the old designs of lamps

I now have most all my house lamps on LED, some CFL & halogen G9's (soon to be replaced). 

My kitchen has CFL in ceiling downlighters,  but under cupboard I have LED strips, these are self adhesive flexible lengths cut to fit (exactly) with about 2 LED's per inch.  Instead of 3ft & 1ft fluorescents that sort of fitted some of the undercupboard area,  I now have end to end lights on every linear inch available - very nice effect & because of the very uniform lighting spread enough light to work with despite that the actual lumen number is less - but 50% less watts !!!

George plenty of us have been doing this for some years now but we don't bleat on about it all the time.

Current bulbs are so much better than those of ten years ago in terms of brightness and speed of lighting up.

Dear Tom,

 

Just because you have already converted to LED is no reason why others may not choose to discuss it now.

 

After all the thing that is new is the release of LED lamps that fit the conventional bayonet and screw type [Continental] fittings, currently used for incandescents. 

 

If you had to fit specific LED fittings the conversion no doubt was either part of a rewire, or was much more expensive than it would be nowadays, when normal lamp fittings can be retained.

 

However - if you think this discussion is superfluous - then no doubt that you could well have ignored it, rather than simply being negative about what has been in all other ways apart from your quoted post, a positive discussion.

Before everybody jumps on the LEDs are brilliant (pun intended) bandwagon, there is a down side.

 

The one SMPS I have that creates so much RFI that I can't keep it out of my audio system is inside a GU10 LED lamp.

 

They're not all sweetness and light (also intended)

The noisy LED issues (& rumour propagation) is mostly historical leftovers from 1st generation lamps & what we have now with cheapo knockoffs found around the cut price & www market. 

There are noise control guidelines in the LED industry & the quality manufacturers follow these more or less to the letter.  The noise modern well designed lamps emit is small & mostly inconsequential - I could however agree a potential effect is possible with LED's on the same power circuit as hifi,  but not between a lighting circuit & hifi power.

Yep.

Although a poor quality LED light's mains wiring can form quite an effective antenna for radiating 'crap' far beyond the source.

Actually, this isn't actually a 1st gen product, nor is it a 'cut price knock off'.

 

The problem is that, unfortunately, due to the configuration of the house, it HAS to be connected to the same mains circuit as the audio equipment.

I recently swapped out the incandescent floods in my kitchen ceiling for LEDs. The kitchen is noticeably brighter, even though the LEDs were sold as equivalents for the ICs that I took out. Everything is great except that the dimmer doesn't get them very dim--only to about half intensity. Are there specialized LED dimmers available?

Posted on: 01 December 2014 by Mike-B

LED's cannot dim to low levels such as incans & halogens that can go to visually off & half is probably as low as they will go. 

LED works differently from incans; when working the light is actually flashing on/off at high frequency like a strob (try wagging your open fingers hand around, you get the stopped strobe effect)  Dimming slows down the flashing Hz - keeping the same colour temp (K), - but it can only go to a level that the driver & the dimmer system can work together with.

 

Take a look at a www technical guide info sheets such as MK have on their dimmers.

Are you commenting on the right thread?  I can't see how this comment fits whats been said previously

Posted on: 04 December 2014 by trickydickie

Back on topic, thanks for starting George it was most timely with my own mini project to replace some lights.

 

I have changed our low voltage MR16's in the kitchen from 20 Watt halogens to 4 watt LED's with good results.  We have 12 of these in all and the light level.quality is good and we didn't need to change transformers.

 

It took quite a bit of searching to get ones that were comparable to the Halogens.

 

I'm now looking to do the same in the bathroom which have the smaller MR11's (20 watt again).

 

Has anyone found a decent one that isn't too expensive, unfortunately the make I used for the MR16's don't do an MR11 equivalent.
