They last almost indefinitely, do not go dim, do not need warm up time and use 10x less electricity!

These are LED light bulbs, lamps, and tubes! Don't confuse these with awful "low energy" fluorescent ones you probably have now.

LED lighting now available in EVERY imaginable type, size & fitting. It is now being produced in China and is a massive improvement over the awful "low energy" fluorescent lamps we are using today.

An old style INCANDESCENT filament lamp as invented by Edison* takes 100 watts of electrical power to give you the light output you are used to getting from a 100 watt bulb/light. 

The ones shown above here are 10 watts only input. But equivalent output to a 100 watt traditional bulb. And come on with 100 percent brightness instantly. And do not wear out or need swapping for about 10 years (estimated).

A LOW ENERGY FLORESCENT (the ones you likely have already) take around twice the electrical power to give the same light output. And they flicker, take ages to warm up and start to go "dim" and lose light output very quickly as they age.

So changing your complete house over to LED lighting today, is going to save you a lot of money long term.

They cost 10x less to run than incandescent lights. They cost HALF AS MUCH TO RUN as so called EFL or LOW ENERGY lamps that we are mostly using today.

(*not actually true! He didn't invent them it was a collaboration)






100 watts of power gives the amount of light you are used to! Lets call it 100 Watts of light. Which isn't correct but for now its good enough.

So 100 in gives 100 out. This was what everyone used for most of my life.  they make more heat than light, don't last very long.


Low energy CFL lighting.  Here approx 20 Watts gives you your "100 watts of light" output. Same as above but 5 times more efficient.

But... They start off dim, get better as they warm up, and then get dimmer and dimmer throughout their life. And that life may be shorter than we are lead to expect.


10 Watts of power in only! And 100 watts of light out. This gives the same illumination as a 100 Watt old style light bulb. 10X as good!

And they start off at full brightness, do not significantly dime during their life, and that life is quoted as 5000 hours plus. Or practically fit and forget.


After testing a few DIFFERENT LED bulbs/lamps I decided that these things are very variable! Some work great with dimmers. Some not. There are many colour temperatures and so on.


  • Daylight. (very blue, no good for a domestic setting).
  • White, is too "blue" for living areas but fine in a garage, kitchen or utility area. Because these give the greatest light output per watt of energy.
  • Warm White. This is the one you want. But there is no consistency across manufacturers. Some are very warm, some more yellow, some more red. Most people don't notice or care but I do. It doesn't much matter, provided all are the same. It is best to stick to one manufacturer then And order all your LED lamps at the same time from the same supplier. These are around 3000k to 3500k colour temp. I have only tested these on 240v and most claim to work on 110 to 240v AC. I cannot vouch for performance on 110/120 as I haven't tried that! 


First then I changed all the lamp holders in the entire house to E27 Screw thread. as these are more common, and there's a greater selection of lamps, and they are cheaper to buy. Typically around £5 for a 10 watt bulb/lamp and that's a 100 watt equivalent output. That then lets me buy a large quantity or E27 screw thread lamps, or different sizes and types.


I use exactly the same 10 watt (100 watt output, warm white) outdoors, in various external fittings. Be careful though. SOME manufacturers lamps do not like the cold! They go dim and have low output. Others work fine. The perils of buying Chinese!

ALL of my outdoor lights, 3 on the front of the house, 2 on the gate posts, 6 in the back where we drink and BBQ etc, light up automatically via some simple daylight sensors. If its getting dark they come on. At dawn they go off. These things use so little power than it no longer matters that they all stay on all night. My garden and driveway, and the front of the house is always lit well. Makes it easier to park, get in and out of the van in a wheelchair, and makes the whole place more "comfortable" at night. No more security lights flashing on and off as people move around.




This is known as a Corn bulb. Can you guess why? These are available in 2 watts, up to 30 watts or more.

The ones I use are either 4 watts (equal to 40 watts) in say my living areas, and there are 4 in wall lights and three in the central fan/ceiling light.  Or 10 watts. Equal to 100 watt incandescent. The 10 watt ones are used outdoors too.  Some use SMD LEDs some the round glass type. SMD type are more efficient and maintain brightness better.

Every type of lamp/bulb is available.

Take a look on eBay.


Including strip lights, or tubes as shown below. I use 3 of these 1800 long tubes in my kitchen, 2 more in the garage. I also use 1200 long ones in my en suite bathroom. These too are available in white (ok in a kitchen where lots of light needed) or warm white.

They replace the old fluorescent tubes. They take half the electrical power, and give the same light output level. Actually a little more, because ALL the light comes from one side of the tube. Facing down.

These are 20 watt tubes. They actually take 18 watts measured.

You need to remove the starter from your existing light fittings, and throw it away. And also connect the two wires that go to the "choke" together. Takes a few seconds to do. And its easy enough with one block connector.

Again these come on at full brightness and will not go dim or flicker.

Actually in use in my kitchen. There are two more behind me.

Also in the kitchen are these night lights. 1.5 watts. Enough light to raid the fridge etc without bothering to turn the proper lights on!  Note that this is WHITE rather than WARM WHITE...

10 watt corn bulbs like this, give 100 watts of lighting (equiv) in the hallway, in bedrooms, etc

Some can be dimmed. So these in my bedroom/workshop are used at full power when I am building powerchairs or model aircraft, but dimmed as needed the rest of the time. Some dimmers do not like LED lights. Some LED lights do not like dimmers! You need to test... There are actually 4 of these so 400 watts worth of light when required!

At about 10 percent brightness...

These are not dimmed, but its daylight and I used flash. These are 4.4 watt each so 44 watts equivalent warm white per lamp. In my hallway.

OUTDOOR LIGHTING like the 3 at the front of the house are each controlled by a day/night auto sensor. These are all just the 10 watt warm white corn bulbs/lamps shown at the top of the page.

More of the same... 10 watts, 100 watt output. The 3 of these light up the driveway great, as well as the house every dusk to dawn. And use so little power it doesn't matter.

And lit up! Its not dark yet but you get the idea. 30 watts in total. The same as my phone charger!

Another in the rear of the house

And on the side of the garage to light the patio. Look through the glass and you will see the ES Corn bulb. 10 watts... Again auto dawn to dusk.

And another, with a sensor shown. One sensor can do about 100 of these 10 watt lights!  I only have 9 outside I think...

Including these ones in the gate posts to help light the drive, and stop my GF hitting them. These are 1.8 watts, and dawn to dusk lit automatically.

Not dark enough. But lit!

My power bills have HALVED since I replaced all the old security lights, as well as every indoor light. I even swapped the ones in the cooker hood, and inside the fridge!

Left - to right. Warm white 10 watt (100 watt output) Surface mount flat LED bulb. Next, same thing but conventional LED'S, Last a pair of 20 watt white LED bulbs. They are for my workshop, and give the equivalent of 400 watts of white light with 20 watts each of input power. Good enough for photography...  At the back Coke can for scale, another 10 watt warm white, a MULTI COLOUR REMOTE CONTROLLED 4.4 watt "mood" LED light... These are for table lamps, special effects, etc. Equal to a 44 watt normal incandescent.

What are you waiting for? The sooner its done the sooner you can save some money.
