Lightbulbs... CFL v Incandescent v Halogen v LED v .....

A while back we replaced many of our standard Incandescent Light Bulbs with CFL's (Compact Flourescent Light)
Many of which were supplied FREE by our local Electricity Supplier, and just before the EU banned Incandescent bulbs, Supermarkets were selling CFLs at rock bottom prices, I think we paid 10p-25p each for loads of them
We have a lot of light bulbs / fittings !!
Mostly OK, though the IKEA ones do seem to have a very short life !
However, in some locations, with fancy triple "Chandeliers" the light output is noticeably dimmer.
This is especially true at the top of staircases.
At night, got a bit fed up with carrying a powerful but small torch to avoid mishaps going down the stairs, I did a bit of Scouting around  Towns shops.
I found Treasure !!
I know you can get "Industrial" versions of incandescent bulbs to get around the ban, but none that are SES Candle style small bulbs, which many of our light fittings are.
In two shops, eventually, I found packs of 60w x 3 incandescent Candle bulbs, and single 42w (=55w) Halogen ECO Saver bulbs.
There were extortionately priced though !!
The 60w x 3 were £1 per pack, and the 42w x 1 were 49p each...
All were dearer in specialist lighting shops, many times dearer.
So I lashed out and bought quite a few of each. The shops are not exactly local.

Doing some light level tests at home, using the EV scale on a photo light meter, both the 60w and 42w bulbs gave out a similar amount of instantaneous light.
And they are both dimmable, a plus point.
The CFL's on the other hand, as expected, gave around half output at startup, only reaching full brightness at around 6 minutes, and then still two EV Stops less than the others.
Top  of stair lights were thus left on for long periods at a time, to get around the potentially unsafe lower light levels.
Perhaps 4 hours, compared to a minute or so with the incandescents, not much energy saving there !
Top of stair bulbs replaced, now so much brighter, and safer.
It's almost like daylight.
And a much warmer colour temperature. 2,800K

I did look at LED bulbs, but not very good write-ups so far, will probably get better.

Have you become disillusioned with CFLs too ?
(Thank you spellcheck)
I find the CFL's don't seem to last more than a year,, the ones that are on a lot, so I think when one blows in the future, the Halogen ECO is the way to go, rated at 2 years lifetime (1,500 hours I think) and 8,000 cycles. 2,800K and 624 Lumens, which is a lot.

Re: Lightbulbs... CFL v Incandescent v Halogen v LED v .....

if your happy using the cfl's and have a stock pile of them there great,
personaly I have a bunch of led lights instead of the gfl/cfl ones because you don't need to flick the switch 2 minutes before you intend to see into the dark space (important for stairs/bedside lamps)  however I have left cfl's in the some areas where instant light isn't important.
the led's give out the same amount of light in the same colour as the cfl's but there is zero warm up time and zero heat dissipation (the bulbs stay cold), the main problem most people have with led's is getting the wrong colour lamps, or there complaining that the 2 year guarantee for the bulb isn't enough .....

I have an increasing number of LED bulbs around the house and I'm very happy with them...particularly the energy savings they offer.

I do not understand why the EU wanted to ban the tried & tested Incandescent light bulbs for
@least one does not have to wait for the Incandescent bulbs to warm up to get a brighter light, which are better for the elderly / infirm / hard of sighted etc

I don't have to wait for LED bulbs to brighten, they're instant on Smiley

Started to fit more & more led lamps's at work.
There much cheaper to run, they don't give of heat, the beam pattern is really focused on the spot lamps & there maintenance free.

Perhaps I am unlucky but have not had much luck with led lights which have been purchased from various sources, true the light given out is good but 6 or more have lasted less than a few hundred hours before burning out  compared to the advertised life of 15,000 hours so what I save on electricity costs is being spent on new bulbs.
Where do you buy your bulbs from .?

Re: Lightbulbs... CFL v Incandescent v Halogen v LED v .....

We're mostly LED's now, inside and out. A couple of ordinary bulbs in very low usage areas.
I buy all my LED's from eBay suppliers based in China/HK and have had no problems. Those that have died early have been refunded by the supplier in a timely fashion.
We have more than 25 in use.
They are not all cold though - high wattage ones (8w) chuck out a fair bit of heat so are best kept away from prying fingers!

Re: Lightbulbs... CFL v Incandescent v Halogen v LED v .....

My only experience of LEDs so far has been with my torch, which uses the Cree XP-G R5 LED. The Cree emitter gives out masses of light at higher voltage settings (up to 337 lm) but gets very hot on high. At low (5 lm) it has a battery life of 152 hours per charge using a Panasonic 18650 battery.
I have a family member who has LED lighting in their home but the bulbs use an array. They also give off a lot of heat and aren't especially bright (my torch provides more light with a single emitter) but I don't know enough about electronics to know whether a single emitter is better than an array. I assume their lighting uses cheaper emitters.
Another family member was an early adopter of LED lighting in the home and had the lights (flush ceiling mounted) by an electrician. Within months the fire brigade were called out as the fire alarms were set off by a large smouldering area around the lighting in the attic which could have been nasty. According to the fire brigade the lights were correctly fitted.

Re: Lightbulbs... CFL v Incandescent v Halogen v LED v .....

many devices use triple emitters or more connected in parallel so if one goes you still have light, I have a variety of led's around the house and most of them are relatively low powered units  (4w or less) and tend not to get even warm to the touch some of the other units are 11w (desk spot lamps for soldering) and those do tend to get rather warm
but they all use up less electric combined than the poxy fluorescent striplight in the kitchen, older units rather like halogen spots were often 20w+ from a single emitter and should of been fitted with cooling fans but for some reason the manufacturers neglected to mention that when selling them as hidden lighting.......

My last purchases were these
I replaced 8 x 40watt Halogen bulbs with these and my electricity meter is greatly relieved. Smiley

Has no one considered Light Emitting Plasma lights?  Highly efficient and very good for cultivating herbal substances.

We could reconsider LEC units as a cheap alternative.

LEC = Light Emitting Candles.

well that would certainly give the Norwegians something useful to do with all the seal fat and whale fat they normally chuck overboard, tallow would certainly be a much better option if it was cheaper than currently priced Smiley
