LED HELP!!

[Bertyboy]

Hi Funsters,

Looking to change bulbs in my camper to LED they all seem to be 10 watts. QUESTION: Do need the same wattage in LED or does one go for a lower wattage? also best sites to order from.

Thanks
Bertyboy

We had excellent service from Aten Lighting -

I'm sure they will give you any advice you need.

Lower wattage...probably about 1-2 Watts

It's the luminosity your need to match, not the wattage. Typically an LED lamp will use between 10% and 20% of a halogen, and they are improving all the time.

If you get the same wattage running off the same voltage you are using the same amps! Go for an LED that will be bright enough.....you can get warm white as well as bright white.
I swapped my 20 watt bulbs for 1.2 watt LED and the brightness went up

Can I just say I hope all you fine people get some nice flowers from these bulbs.

And get suitable lamps for your light fittings

That's the short answer. Here's the long meandering answer.

Incandescent lamps work by heating a metal wire until it glows white-hot (over 2000 degrees C). If it was in ordinary air, the oxygen would react and destroy the metal wire instantly, so it is protected by a glass bulb containing an inert gas, like nitrogen. This process is very inefficient. A 10 watt incandescent lamp produces about 130 lumens of light. Over 90% of the 10 watts ends up as heat.

An LED works by charge carriers in a semiconductor junction recombining and emitting light photons. This process is much more efficient in terms of producing light from electrical power. Typically it can produce the same light (130 lumens) from about a tenth of the electrical power (about 1 watt).

Look in any shop, supermarket or even street lamps. LED is a no-brainer for running costs. It's an even better idea in a motorhome with a limited store of electrical power from the battery.

About the only downside is when you replace the vehicle sidelights, indicators or brake lights. The 'intelligent' monitoring system sees the huge reduction in power consumption, thinks the lamp has blown, and throws up a lamp fault code. Some of these replacement vehicle LED lamps even have a built-in 'ballast resistor' that deliberately wastes enough power for the system to think it's an old-style incandescent lamp.

You do not have to swap for the exact 'equivalent brightness'. I swapped all my 10-watt interior lamps for '20 watt equivalent' ones. It's much brighter than before, which I like, and about a fifth of the electrical power consumption.

You usually have to choose between 'warm white' and 'cool white'. I chose warm white, which looks exactly like the old incandescent lights. Some prefer cool white because it renders colours more accurately, or because it just looks more modern.

I got my last lot at NEC Oct last year there was a guy in a stall with every bulb going. No postage and if wrong you could take it back and swap.

got mine from hong kong via fleabay. £10 for 10 free delivery. still going strong.

Aten sorted mine out and they are great. No heat, lower power consumption, and NO interference
