I'm slowly replacing bulbs around the place with LED equivalents, and today I bit the bullet and swapped out the fluorescent tube in the kitchen. I'd been a bit hesitant because I wasn't sure how it would stack up against the more traditional light but I have to report that it's a complete success. The light itself is fine, suitably bright, non-painful, and apparently using 60% less juice. If you're considering it then I'd say go ahead and do it. The tubes are more expensive (A LOT more expensive if you don't shop around) but I picked up an Energizer T8 5 foot/22W 6000k/2250 Lumen daylight tube for just under twelve quid, including the 'special' starter that you have to replace in your existing fitting. It's the equivalent of a 58W fluorescent, and I believe that the 2250 lumen rating is roughly equal to a 150w incandescent lamp if I've done my sums correctly. Right, that's done my bit for the environment, this week.  |

I've been slowly replacing our downlighters (there are loads of them in the house) with 12V 5W GU5.3 LED ones. They are very bright and do the job nicely. Dimmable ones are more difficult to find but I ordered three for the downlighters over our dining table and they have been excellent, too.

If everyone updated their lights to led there would surely be a major drop in the UK power usage ?
I have about 30 lights in my house - a few years back, they would have been 60 watt each = 1800 watt. first replacing a few years back with mini-fluorescents reduced that to about 600 watts. This year I've replaced with led, total power use now about 360 watts.
Only problem has been that my old dimmer switches don't work anymore so I removed them !

It's also a hassle replacing the transformers when changing halogens for LED. It's halogens which are the most power hungry as often people have 6 to 10 at 50W each. It's expensive to changeover for those who can't do it themselves. Progress....

Had a pukka fire alarm installed at work.
I was disappointed in the huge amount of light produced by the LEDs in the exit signs.
Such a waste I thought.
Until the guys told me the lights produced consumed 4 (four) watts !

Lots of work to replace the transformers and dangerous to run LEDs with the wrong ones - I was told |

Like many of you, I have swapped bulbs from filament though fluorescent to LED. 20 years ago when moved into my house, the lounge alone was 6x60W = 360W, then 6x23W=138W and now about 6x5W=30W.
This tremendous saving is most evident in mobile applications like camper vans or leisure boats. With traditional bulbs, the leisure batteries would be depleted after one night. With LED you are good for a week. With modest photo voltaic panels they will work constantly.
My recent area of interest is the type of "white"... daylight? warm? or cool blue? Daylight is really good for seeing stuff, but most people prefer warm white for relaxing during the evening. You can buy LEDs which go through the whole RGB spectrum. However, what I would like to see is white bulbs which can switch between the different flavours of white as required... For example daylight for reading and warm white for chilling out.
Cheers
Sean

I still can't get used to a strip light that comes straight on instead of the usual sputtering and stuttering.  |

I've done 2 of the 4 tubes in my workshop. As bright if not better.
No need for any starter bypass stuff. Just go straight for the AC.
Expect them to last much longer too..
I've had several of the spot ceiling downlighters go flashy.
Not had any problem with the under kitchen cabs led strip downlighters 3 years in. Touch wood.

We have some under cabinet strips that keep going.
Expensive things even as old style
I'll go looking for LED equivalents
