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 ...

Dear Howard,

 

That's the whole point of the thread. Yes. In a single efficient unit that fits your normal lamp holder.

 

Bayonet or screw fitting. For a cost similar to the slightly higher current CFL [terrible start and dull light] and the significantly worse current consumption halogen ...

 

Philips is the mainstream maker, and they have solved the mains noise thing, as it affects replay - this being a replay Forum ...

Dear Richard,

 

I am sure that all that stands in the way of what you want. There seems to have been a spurt of activity with domestic lamps for mainstream applications this autumn, and no doubt that in a short while there will be LEDs for every single application.

 

The change to CFL lamps that was promoted a few years ago perhaps has stood in the way of LEDs till now as much must have been invested in CFL manufacture for normal light fittings. It seems to me that there will soon be LED replacements for all the varieties of CFLs Halogens, and old-style Incandescents. Perhaps the thing would be to wait just a while, and then your wish will be rewarded.

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.

Thanks Mike

 

I'm sure the Megaman or Philips ones would be good based on my experience of the former and George has reported good results with the latter.

 

The MR16's I found for the kitchen only worked out at £2.50 each from a specialist LED retailer, i.e. a reputable source and being tight was hoping to find similar in the smaller size. The cost mounts up when you need quite a few.

 

I may need to wait as George suggests, no rush.
