Hello, I work in lighting and I find that old school lamp with a adjustable neck fitted with a 100 cree LED A19 daylight 5000k bulb works well for me. I can adjust it at any location to get the right angle of light. WE have 4000 lumens bulb with standard socket that I want to try but I am afraid it may light up the entire house.

 

HI -

 

I retrofitted this old lamp with twin LED tubes, a bit expensive compared to using an A19 bulb, but it works a heck of a lot better than it did with the original twin flourescents.

 

Cheers!

Im still in the process of trying bulbs. I like daylight 5000k minimum 100 watt any brand will suffice. I also like phillips 100 but they are pricey. Can you adjust that lamp to see at any angle.If you can that might be a better choice.

The lamp is adjustable, you can move it into just about any position you want. And yeah, the box on the left is a fake Gerstner from Costco, the boxes on the right are cheapie unfinished boxes from Michael's crafts that I finished and lined with felt to (sort of) match the toolbox. 

 

Cheers!

Update:

Well I'm back off holiday and have now had a chance to take a look at the lamp.

I tested the strip of LEDs that apparently failed and they all work individually. But agitating the first led in the failed strip caused them all to come on. So i re-soldered that LED to the plate and all is well again.

I've been playing with different LEDs to make a cheap DIY bench light. I got 5 .5m rigid LED strips for about $13. 180 5630 SMD LEDs in total produce a more than adequate amount of light. It beats the crap out of the small LED desk lamp I'd been using. I've just got to figure out a wooden or aluminum mounting system.

@Rafal

Thanks! It's supposedly 5000k daylight. In reality, it's a little on the cool side. Even though I prefer warmer lighting, I've found that I see watch parts better under cooler light.

@ro63rto

It's not color correct. Both the color rendering and apparent brightness are better than in the photo. I'm thinking of getting a set of warm LEDs of the same type and mixing 3 cool and 2 warm.

@oldhippy

I really want to stick to LED, but that fluorescent light seems like a really good deal at Ofrei.

$70 experment?  ill go blind first.   the original watchmakers used sun light thru the window.   Vinn

Omar was referring to the lamp from oldhippy's post. Looks like a pretty nice fluorescent light for the money.

sorry,  let me  re fraze my  coment on lighting for watch bench work.   light from two lamps, a combination,  one fluorescent and one regular bulb,  will provide good lighting without glare.  has for years.   whatever doesen't cause eye strain.

Don. Is it the photo or is that colour correct?

Looks very blue. If so you may find it strains your eyes after prolonged use and, if used late at night, cause you to take longer to fall asleep.

whoa! i didn't realize the falling asleep part! good to know. i've never heard of that before.

Definitely something to keep in mind. If I read on my tablet before bed, I turn on the 2700k night mode and set the screen brightness to -35%.

I prefer warm lighting for almost every other application - I even buy warm tinted led flashlights. The desk lamp I was using had a warm and cool setting. I just found that I saw the small parts better with the cool setting.

How do you think this lamp will compare to the one you posted. I was about to buy it when they raised the price $40 after I showed interest and sent a question asking if it was available in 110V. 

So I decided to look at other options.

Without actually trying one, I cannot comment.  

All I can suggest is that you read the reviews and make up your own mind.  Sorry not to be much help with this, but without first hand knowledge, I don't want to recommend something that you may not like.

There's no way to pivot the light in the horizontal plane ie it's always facing straight down.

    • I dont understand why a patreon membership would have limited places ??
    • Welcome to the forum, enjoy. It’s highly unlikely you will be able to purchase a new bezel look on eBay for a pulsar watch for repair to find a bezel.
    • just one little minor reminder here this isn't your normal balance wheel.  pages 17 and 18 are what you really want to be looking at. normally studs don't turn but this watch has the etachron system designed for lots of adjustment. Personally I would try to rotate the stud back to where it's supposed to be. If you're lucky you didn't actually bend it at the stud it just looks really bad as the stud has been rotated grossly out of position.. I think things will look a lot better if you put the hairspring back where it's supposed to be by rotating the stud. it's hard to tell if you actually did bend it at the stud or not we won't know until you rotate the stud back more or less where it's supposed to be. Then you want to pay attention to the manual of how to put the hairspring back in the regulator pins because yes they rotate also and they rotated specific directions otherwise bad things will happen to your hairspring. so initially you can open up the regulator as wide as it can go and don't worry about closing it until thing everything is right then you can close them a little bit

    • Hi @Jon, so, from one extreme to another the beat error is 0.1(min.pos) to 0.2(msx.pos), and as you mentioned the rate does up and down dramatically. Also checked the position of the collet, and the collet is not central to the jewel on the balance cock. Balance moves freely, per my understanding.   So, after 24h the ampl. fell down by approx 20 deg, which I would assume is expected. After adjusting the endshake I believe I gained around +10 deg. of balance movement. Which is great, and overall the balance is not at 220'ish deg.   What I did next, some might think is non-orthodox, but was wort a try. I too the mainspring out, checked again for endshake and if the pin moves freely, and cleaned everything. Usually when installing the mainspring I would use some barrel grease on the barrel walls, install the spring and put a 2-3 drops of D-5 oil on top of the wounded spring and in the places where the arbor sits. This time I took the spring and applied a ultra this coat of Molykote Dx paste on the whole spring, before installing it in to the barrel, and added some oil to the arbor as usual.  The result improved, at a full wound the balance produces about 230-237 deg. @JohnR725 I'm getting closer to 300 😃   What I am noticing, there is a fluctuation in amplitude. With time it would rise and drop about total 8-10 deg in an interval about 2 minutes. I assumed this ruled out the power transfer from the barrel itself. So I took the gear train out, cleaned and lubed.
