L.E.D. changeover.

Today I have at last completed the changing of all the halogens inside (and the awning light) of my van. It has been a costly exercise, mainly because I started with 4 at £11.00 each, before finding a new source at £4.50 a piece I also had to buy 2 M16 spots that were £11.00 with p&p. So nearly £80.00:eek::eek: on bulbs but I think I can now not worry about leaving lights on or changing bulbs they are supposed to be good for 50,000 hours, I don't think I'm good for that long so they will see me out and if I do change vans I will take them with me. So I will let you all Know how things go with my now (with solar panel) self sufficient accommodation.:):);)
 
thats quite an expence for the humble light bulbs, rick
you must be the only man who has to enter light bulbs in his
last will & testament :D
 
The LED lights i bought were about £30 for 10 but i had to shop around, it depends on what type you want. :)

Well Nick, I worked out that at the rate I use lighting they should last for 333 years, just wish I could upgrade me so I could use them till they fail. So I will have to hand them down through the generations, to make sure they last as long as they should and if they dont then Iv'e got the address so they can get a refund.
 
You could have always done what I did (being a tight a*se) and that's to simply change one in each area!

Afterall how often do you want ALL the lights on?

So I've changed the awning light, one in the lounge and one in the bedroom, I've left the loo as I wanted the brightness for shaving etc... and how long do you spend in the loo (answers on a postcard please).

might have been a good idea to do them as they failed one at a time it would have cost the same but would have hurt less a bit at a time
 
Led

I added some LED pastilles in the interior. They are really energy-savers. But as their tone is blueish-white; my wife doesn't like them. She is not found of purple tomato-soup or brown wine.:eek: But I think this will change in the future; it was the same as with the TL-tubes 50 years ago.
As for now LED's are quite expensive; but prices will go down and when red wine is red again: I change all the halogens for LED's :D

Anyone have any links for cheap LED Bulbs and lighting?

I still have 6 available, they are a straight replacement for the 2 pronged halogens that are in most spots. They do not replace the all in one M11 or G4 units, £4.50 each + £1.00 p&p. P.M. me if you want more info.

Now PLEASE don't cringe :confused::confused: when I ask
what are LED Bulbs? :confused::confused:
and I am now probably going to die with embarrassment asking :eek::eek::eek::eek: and probably not live it down
Yes I do know they are light bulbs:D:D
 
Hi Polly hope this explains it to you.

The incandescent lightbulb is a miracle of modern engineering. It requires a vacuum inside, blown glass and special filaments to work. Yet despite more than a century of refinements, an average bulb emits just 15 lumens of light for every watt of electricity it consumes. As a result, simple lighting accounts for 22 percent of the electricity used by buildings in the U.S. Now a team of engineers and chemists has created a carbon-based series of light-emitting diodes (LEDs) that operate at the pinnacle of efficiency while emitting a strong white light.

Electrical engineer Stephen Forrest of the University of Michigan, chemist Mark Thompson of the University of Southern California and their colleagues created the so-called organic LED by combining two layers of phosphorescent diodes--to release green and red wavelength light--and one layer of a fluorescent diode to supply blue wavelength light. Together, they produce white light much more efficiently than current incandescent or fluorescent bulbs. "A 100-watt bulb is about 15 lumens per watt and we're at about 25 lumens per watt just on the lab bench," Forrest says.

The diode also requires a lower voltage than purely phosphorescent devices do thanks to its fluorescent component, the researchers note in the paper presenting the finding in today's Nature. Furthermore, because the organic layers are only 10 nanometers thick, and transparent when turned off, they can be built into walls, furniture or even windows.

Challenges remain before light-emitting ceilings can become common. Among other things, scientists will need to find a material to encase the sensitive diodes. "This doesn't need a vacuum but it does need a moisture barrier and that can be expensive," Forrest explains. "The biggest barrier to large scale production is simply cost. It costs very little to make a light bulb today." Nevertheless, the development of the novel LED may well signal the dimming of the lightbulb era. :):):):)

Thanks profesor, have you got any idea where we can get cheap replacement bulbs, I have all my 12v on led's, and 2x240 25w lights for when we are on hookup.
Cheers, Pete
 
Hia
Now come on Bigboack

I am actually glad I asked
as you have made it very clear to me
I think:confused::confused:

and zee zee whats all this 12 volt LED and 2x240 25w

the pair of you have completely confused me

I may have to think twice before asking another question :rolleyes::rolleyes:
 
.

OI pigpoke ...(smartass).. i want all mine replacing please...:cool:
so get yer ass down here.. i'll provide the food, overnight accom and the wiksey lessons/appreciation classes.

i'll wait till yer disease has subsided though :eek:


regards :D

Hi Polly
In short an LED light is a light source that uses far less electrictity, therefore if you replace your normal lightbulbs in your MH with them your battery will last a lot longer. The downside is that the best price for a replacement LED bulb is about 50 times the price of a normal bulb. Thats about 50p for the 12 volt bulb in my interior spot light about £3 for a replacement LED to fit it with posting from Hong Kong.http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=160375933550&ssPageName=STRK:MEWAX:IT

If you replace all the light fittings with LED only fittings you can buy cheaper, about £2.50 a bulb. If you are a serious Wildcamper and need to use as little of the battery as possible its well worth the expense.

Like the new low energy bulbs we now all use in our houses expect the price to come down over the next 2 years, my new company car has come with all led bulbs so I would expect to see them on sale in Tescos before long.
