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.

    • HWGIKE#57 Valex FEF 190 15 jewels Swiss lever full service and repair This one was waiting for a balance staff replacement in my cabinet parts and case cleaned up with a new balance staff and a 4th wheel as the original 4th wheel had a broken pivot for the off center second hand. I never attempted a balance staff replacement before however I received a Bergeon Molfres (i was hunting it for about 2 years) and with the help of it I managed to remove the old staff and riveted the new one in. It also received a new MS, crystal and the hole for the MS arbor was also tightened. With the new MS now it has an acceptable performance meaning that the amplitude goes up to 280 fully wound, has an acceptable beat error and I have the two nice lines but only dial up, dial down is not as nice and I could not figure out as why. I have the two lines but the amplitude is dropping to around 230 and the lines are a bit hairy. Both dial up and dial down the lines just go up and down without seemingly any pattern. I cleaned the movement two times, and then a 3rd time pegged out the main plate and train bridge holes but made no change. Both the HS collet and the roller table was too lose on the new staff... I did not count how many times I took the balance cock off to sort out the HS collet, the roller table and the beat error, somebody before me also shortened the HS by pushing it out a bit and it seems every time somebody is messing with the end of the HS the protruding bit is most of the time twisted bent etc. This one was probably one of the most challenging repair and service. I might take the new MS out and clean it lubricate it as I just pushed the new one in to the barrel from the retaining ring. Plus started to re-read the theory of the escapement and how to analyse the graph on the timing machine: Greiner Chronografic Record manual. I am also thinking to put the watch on a 24 hour long run with the eTimer SW it once helped me to figure out what was wrong with a watch. There is an interesting part of the Greiner record manual talking about the pallets and the end shake of the balance and pallet staff. Maybe this is my issue? Who could that possibly identify? After a few years now I am still without a clue how could watchmakers make parts I can only see with my microscope or how could/can they carry out complicated services impossible to do.. real magic..... .... ..... before I sent this post while the pics were uploading I had an idea, i was browsing the possible outcomes on the timing machine I had one for magnetism..... so I demagnetized the movement and it is not hairy now.... two really nice lines 0.2 ms beat error still a bit wavy, but a lot lot better..... argh....  
    • Hi there, welcome here.  
    • yes the advertising revenue should generate money. The question is how much money? Then as far as the cost of the website goes that's relatively easy to determine? all you would have to do to grasp costs and profitability would be to go to the link below and you can actually get a website for free try it out for free I believe you get no advertising initially. They also talk about that they'll help you out they have marketing tools and some sort of paid subscription or something. So I guess were shopping for a whatever just ask them what would a maybe could use this one as an example in other words it's going to look basically identical to this is going to have advertising a paid subscriptions what's it going to cost? After all they want to sell or give us a message board like this they should bill answer the questions as they're the people who did the software for this. Yes they really said you can have a free discussion group at least to start. https://invisioncommunity.com/ I was curious about the monthly supporter thing where exactly do we find that on this message board? A quick search I'm not finding it so obviously I'm not looking in the right place?
    • Help me out here, but with all the advertising on this site (which I don't mind) wouldn't it pay for itself or even make money for the owner ???
