Got to agree with Geo, though I hate telling others how to work, we all develop our own preferences and techniques. 

There's more than one reason I'd advise against a magnifying lamp based on my limited experience using them:
it can Interfere with hand eye co ordination. I think it has something to do with the distance between your eye, the lens, and the thing you're focusing on, and if these things aren't a certain way, your brain gets confused by the information. 

The optics of the lens don't tend to be stellar, either, this isn't something i'm a particular expert on either, but I'm using big words here because photography is a hobby and I've read about this, so I have some sense of the lingo.
 
You can get a a couple of forms of 'aberration' (distortion, basically) so disregard this if you find a bench magnifying lamp that claims to be 'aplanatic' which means it's corrected for these things. 

I found the one I used had:
Spherical aberration, the object is larger or smaller at the center than it is towards the edges of the lens. (which is true of a lot of eyeglasses, but much much less noticable because of size/how they're used.)
and Chromatic aberration, where basically the lens is acting as a prism, splitting up the bands of colors, you see red green and blue haze on the outlines of things. 

Bit of a ramble, one of those topics for me, I could go on.

What I had over my work bench was a strong strip light which didn't give off any heat and many different eye glasses. It was all artificial lighting as there wasn't any windows in my work shop, I bet you couldn't get away with that now. Back in the 70's when Heath was P M and I think it was called three day a week, when power went I couldn't do a thing in the pitch black, to top it off we didn't know when it would happen. They were the not so good old days.

      Hermle 340-020 slowing down as days go by

      By DirkP121 · Posted

      Update, I discovered that I could change the mainspring by removing the arbor and sliding it out from between the front and back plates. So I put a new mainspring in. This it what I  get over a 7 day period After winding                                          amplitude is 1 1/2 turns plus a few degrees.                                                                        ie just over 1 1/2 turns. 1 day after winding     gained 1 sec      no amplitude check. 2 days after winding   gained 1 sec      amplitude 1 1/2 turns                                                                                                              i.e. it lost the few extra degrees 3 days afer winding    gained 3 sec     no amplitude check 4 days after winding   gained 5 sec     amplitude 1 1/2 turns                                                                                                               i.e. unchanged 5 days after winding   gained 7 sec     no amplitude check 6 days after winding   gained 16sec    amplitude just over 1 1/4 turns 7 days after winding   gained 24sec   amplitude 1 1/4 turns. From  Based on video inspection, I am getting full pallet lock. So, my data seems to be at odds with the statement "swing of a balance wheel has nothing to do with the rate". However, I have noticed the banking posts are not controlling the lever position on the right side.  I may have some work to do here.

      Crown Snapped Off - Armani Renato Watch

      By RichardHarris123 · Posted

      I can't tell whether or not some stem is stuck in the crown, I  think so though.  If the crown is stainless steel you could try alum to disolve the stem of try drilling it out. If all else fails, buy a new crown.

      Does anyone use the x5 eyepieces,  when i use them on my different amscope , the magnification changes to x5 but the field of view remains exactly the same as the x10, so nothing gained. The optical lenses can't be swapped out or at least they are not available as far as i know.

      I think maybe we're all a bit dim @ManSkirtBrew 🤣 99% of the time I'm working with the 0.5X Barlow, so mags from 3.5X to 22.5X. When I need a close up of a pivot or jewel, I take the Barlow out, and even put in the 2X Barlow, but it's a nuisance. So like you, I had that D'oh moment, why don't I just use 20X eyepieces (WF20X/10). They take seconds to change, and you keep the working distance. The only downsides are lower field of view, and less brightness.

      At the lowest magnification, I can just get all of a normal wristwatch size movement in field. For some things it's too much magnification, but the nice thing about the eyepieces is they only take seconds to swap in and out. I'm genuinely surprised I've never read about anyone else doing it, to be honest.
