TYPES OF BULB/LAMP
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.
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.
