Screwfix LED lights, bargain!....

I'm going in the morning to buy some of these, great value for ES and BC globe bulbs.

Got to give them a try, replace all the dim energy savers.

Here's the short cut for you:

I would avoid "cool white" and opt instead for "warm white". Cool white can be too blue for home use unless you need a better colour rendition, I bought some for the bedroom and they were rejected by the missus.

Probably some spoon posting on the internet about what a great bargain they are, they sell like hot cakes and voila, no stock.

I replaced the halogens and did eventually get 5W warm white LED's; it took the missus a couple of months to realise I'd swapped 'em

I could write a long and ultimately boarding post about LED light (I'm an engineer for a lighting company specialising in high end LED light) and the problem is misinformation, as well as the market being flooded with poor quality LED lamps.

There are now LED's which are equal or superior to halogen lamps in every way, but take a deep breath when you buy them, they aren't cheap (expect £25 to £30 each for a premium lamp such as a Soraa, marginally less for something like a Civilight).

For the domestic user looking for a lamp which will be close to halogen, look for a colour temperature of 2700k (kelvin) - often referred to as very warm white, and occasionally as warm white (which is inaccurate as warm white is 3000k) and a colour rendering of 80 or higher (this is indicated by a number called CRI or RA) 'premium' LED lamps can be CRI95 - 97, where as a halogen is typically 95 - 98, and noon daylight on a summer day is theoretically CRI100 (although it's not really possible)

The light output is stated in lumens, watts simply refer to the power consumption. I've just completed a phase of halogen to LED conversions for a jeweller, as he was tired of the halogen lamps in his spot lights causing heat related damage, and the new LED's are actually superior. The old adage is true, you get what you pay for.

4000k is quite cool, I'd go 3000k in living areas, 2700k in the bedroom, or just 2700k everywhere. Watch colour rendering, you need a CRI of >80 (or just 80) some sneaky retailers (especially supermarkets) will sell you a lamp <80 - less than 80. The sickly washed out look is due to colour rendering.

If you are looking for MR16 lamps, toshiba are good at an affordable price point, and widely available online.

Dimming is a mine field though, LED's draw so little power that many normal mains dimmers from the pre LED era will buzz and flicker. Look for the Varilight V pro dimmer switch - it's affordable at around £15 and very effective (provided minimum load and transformer / driver compatibility are observed)

4000k makes a room look like a mortuary.

Toshiba LEDs seem to be a good compromise between price and quality. About £10 a pop for GU10s, and the are a very good match for halogens. Their e-core PAR38 lights are better than the tungsten equivalent.

Absolutely. I'd personally suggest 3000k in the kitchen, 2700k everywhere else. If you are replacing a halogen go 2700k. Bear in mind as well that halogens have a somewhat variable colour temperature, so they get even warmer when dimmed where as LED stays true to its colour temperature. For closest approximation;

35w halogen = 7w 2700k LED
50w halogen = 11w 2700k LED

The train :(

Do Led lamps tend to be more reliable than their halogen equivalents? I ask because I reckon a halogen blows once every 2-4 months in our kitchen, which is irritating.

Yes. I've lost a few of the cheap ones, but none of the Toshes have gone in the 2 years that I have been using them.
