I've had a complete change of mind,
Amazon Verified Purchase(What is this?)
This review is from: Lloytron L855BC Studio Poise Halogen Hobby/ Desk Lamp - Brushed Chrome (Kitchen & Home)When I first got this lamp, I was very enthusiastic - a selection of old desk-lamps had gradually died and this was my first foray into halogen bulbs. My original review read, "I now have two of these, I like them so much. It's not the biggest anglepoise in the world, but it's big enough, and twice as big as the cheaper one I made the mistake of buying from a shop last year (once it was bent over to point downwards, it was only three inches off the page!). One of the good things is that the bulbs are GU10, which are easier to manipulate than the smaller, unprotected halogen bulbs, and also you can get them in 35W or 20W, whichever you prefer (you can also get 50W, but 35W is the recommended maximum rating for the lamp. Having said that, 35W is not that bright, but it's acceptable)."
I apologise to all the people I misled with that review - I've completely changed my mind. I grew to find this lamp still far too small, very dim, the light was far too orange, and it only illuminated a tiny area of my desk. If I'd kept it, I'd have switched to a 50W bulb, but I was sick of not being able to recognise any colours due to the very low colour temperature of the light. So...
I've since bought a lamp twice the size, daylight-coloured energy-saving bulb etc. I have reviewed it elsewhere. I now realise that one shouldn't stint on good-quality, efficient lighting.

I may misunderstand your review, but surely the issue you raise concerns the GU10 bulb that was supplied rather than the lamp itself - which, according to other reviews, operates well. GU10 bulbs are available with a daylight Kelvin rating, 130-degree beam and (of course) very low power consumption of around 5 Watts. If you fitted that sort of GU10 to this lamp I think that would address your concerns.

Thanks, that's useful to know. But I don't know what you mean by "and (of course) very low power consumption of around 5 Watts." You mean there are low-power GU10's as well as the usual ones, or do you mean that a 35W GU10 is an equivalent power rating?

Light bulbs are pretty misleading in their terminology. The wattage of a lightbulb doesn't necessarily correlate to the brightness of the bulb, which is actually measured in terms of luminosity (lumens). As such, a 5 watt bulb could have a greater luminous flux and hence be brighter than a 50 watt bulb.
Traditionally, bulbs were never that efficient, and often neither was the electrical supply to houses, so by pumping more power into old light bulbs, more light could be got from them - hence bulbs that could take higher stresses were generally seen as better. But times have now changed.
The key differential here is efficiency. Halogen bulbs typically get very hot, so a lot of energy is wasted through heat loss, meaning that they use a lot of power (50 watts) and produce relatively little light. You can now get more efficient bulbs (and more efficient halogen bulbs) that consume less power but are more efficient, so brighter too. A win-win situation!
