Can someone help me understand LED reading lights please?

[crabapplecrumble]

I need new bedside wall lights and the ones I've looked at all seem to have LED lights. They're all similiar to this:

cometlighting.co.uk/indoor/wall/reading/astro-fosso-switched-led-reading-wall-light-in-matt-nickel.html

From what I've read, there's no bulb to replace, but they last a very long time. So when the bulb (or whatever it is) fails, then the whole light has the be replaced? Does that sound right? It sounds really wasteful not be able to replace a small part but to have to replace the whole thing. Should I be worrying about this, or trust that it really is going to last many years?

I do a lot of reading in bed, so how strong does the light need to be? I currently have a 40W old-fashioned wall spotlight to read by. The one above says it's 2.5W LED. I'm not sure how to measure the amount of light. I've seen some that are 1W, some 4W, but maybe that's not the right measure to be looking at to know if it's going to be comfortable to read by?

I like the small head and bendy arm on these because I think I could direct the light at my book so it's less annoying for dh if I'm sitting up late reading and he's trying to sleep. But would the light hitting the book be too small to light up the whole page, so I'd have to move the book around to see the whole thing?

I hope someone can help - I've been googling for ages, but still don't really understand!

There does seem to be a growth in lighting that uses 'built-in' led lights. I'm not convinced of their longevity yet, as yes they aren't replaceable. Why not buy ordinary light fittings and put LED bulbs in them? Here's a chart for their equivalence.

Or why not get something like a book clip light. The OH has one but that is for a Kindle, but it's a tiny thing maybe an inch long but does the job.

Here's clip-on one

Fittings with replaceable bulbs are going to be larger. GU10 bulbs are typical.
If you want a dainty fitting it will have to be one with an integrated bulb.

Thank you both. I do have a clip on light, which is good for some situations, but I really need to replace our existing wall lights, one of which is broken. I might just go for a non-LED light because if I bought LED I am not convinced they will really last for many years, and that seems such a waste to throw away a whole light plus the cost of new lights and electrician to install. I thought a slimmer, more directional light would be useful, but it's not essential as dh has put up with my reading light for years. I'll look at the LED bulbs for normal lights.

a decent led (Astra use decent components) will last tens of thousands of hours, which is many years of continuos use. You will probably get bored of it before it gets bored of you.

Thanks Millstone - I think I might order the Astra ones. I've been looking for others that I can use led bulbs in, but can't see anything I like as much.
