A dazzling piece of luck
Over the last few years I have been improving the quantity of lighting in my shed. It's not that I'm getting old you understand. It's just the photons are being age-ist, and demanding I use more of them.
Most of the latest editions have been LED flood lights - they have come down in price and put out a large amount of light.

One persistant problem was the drill press though. I'd tried several times to do something but I could never find the right light fitting. On Friday I was in the electrical section of the hardware shop and saw a version of those flood lights, except this one was only 120mm wide by around 100mm tall, so ideal to slip between the column and the spindle.
I welded up a bracket with integral switch box, did a 'fabricated but looks like a casting' wiring break out piece between the main casting and the switch casting, then a bit of connecting into the existing wiring and it works a treat. Initially, I was going to put in another cable gland but could not solve the 'drilling a 14.5mm hole without a drill press' problem. The breakout piece could be removed if a future owner was a purist who did not want a Waldown with an add-in bit

I need to get some long M5 screws for the back of the switch assembly, but the break out piece was sized so that I could move the long screws from the back positions to the front, so I only need two extra screws.
The photos below show the before and after. What they don't show is that before shutter speed was 1/30 of a second but the after shot was 1/60 of a second. The first thing I drilled was a piece of aluminium and it is possible I may need to install a dimmer when drilling shiny stuff.

Thanks for that Michael. Did the light come from the big green shed, if so what was the Item Number please?? Need that as our local is a store and not a warehouse, so it probably won't be on the shelf and needs to be a Special Order.

That LED panel looks similar to the $14 (including shipping) 100W, 10,000 lumen panels I purchased recently from Ali express.

Some more details here
https://www.woodworkforums.com/f245/...41#post2226593
I have fitted this one above my electronics workbench alongside the 4x 27W LED, 2700 lumens Osram globes for a total of 21400 lumens - this helps me see the micro text printed on small components some times even without the use of a magnifying lens
A couple of issues with the Aliexpress panels.
They don't come with a plug so you have to supply and install your own but beware the earth wire on the panel; it's not connected to the metal chassis. I did that myself.
They do get quite hot 87ºC after 15 minutes, in contrast the Osrams get to between 74 and 80ºC in the same time.
The panel has significant flicker - not enough to be seen by naked eye but my camera picked it up with only 1 out of 3 shots showing them as working! The large Osram globes have a phosphor coating which helps smooth out their flicker. This means the flicker on the Aliexpress panels could be a problem for machinery.
Either way the certainty put out the lumens. For $5 they also come in 50W 5000 lumens and was thinking of buying one to try out.

Hi Guys,
Certainly being able to see properly, having good lighting helps !
I'm going to the eye hospital in a couple of weeks time to have a cataract removed from my right eye and then they tell me I will have the other eye done about five or six weeks after that.
However they also tell me that whilst my normal vision will be OK I will need to wear spectacles for reading and anything shorter than my arms. Which I don't at the moment, only needing them for distance.Best Regards:
Baron J.

Mine came from Mitre 10, but Bunnings do have them (inventory number 4371554). This is a 9W version but the Bunnings website also has a 15W version too. The 9W version is all of $20.99, so not bad considering the light output (scanned packaging attached)

According to my eye specialist, based on lighting alone (ie assuming no other vision problems), a 60 year old needs twice as much light to achieve the same visual resolution as a 30 year old. I've really noticed that over the last 15 years in my shed as I have ended up doubling the light out out of my shed lights.
I'm going to the eye hospital in a couple of weeks time to have a cataract removed from my right eye and then they tell me I will have the other eye done about five or six weeks after that.
However they also tell me that whilst my normal vision will be OK I will need to wear spectacles for reading and anything shorter than my arms. Which I don't at the moment, only needing them for distance.
I currently don't need to wear distance glasses but I need them for reading with left and right eyes needing different corrections for magnification and astigmatism.
I wear bifocals with very minor correction for distance, and for reading adjustment - they are also photo chromatic so I don't have to bother to wear sunglasses. They are PITA for really close up work like electronics so I have a pair of prescription reading glasses that are also slight magnifiers the I find useful.
As far as the cataract goes, seeing as I haven't yet noticed any difference between the right and left eyes, the eye specialist has recommended waiting for 6 months to see whether the cataract increases or not. He said if I was a pilot I should have it done but for now it can be left as is especially if I am going to be taken off the meds soon.
Back to the shed lighting - I 2019 did some "real measurements" of the light levels on the benches in my shed and even though I have an average of about 904 lumens/m^2 (lux) in the shed , the average is closer to 600 lux. This is probably due to obstructions in the ceiling under the lights where I store materials and gear.
The lights are also not evenly distributed so the lux does vary quite a bit from 1370 (above my MW lathe) down to 260 lux in the darkest corner of the shed. To further improve lighting in specific places I have added LED spots, so places like the DP and Mill work tables have around 2500 lux. The best lux is under the guard of my Table saw which has 17000 lux but this is because the LED spot is just over 100mm from the table. As MG shows, spots or single globes are not as good as panels because the latter reduce shadows so I'm think of replacing some spots with panels.
Lots of grimy details here https://www.woodworkforums.com/f245/...rements-227941
The weak areas in my shed are my welding table, general workbenches, using Bandsaws and grinders. I do have a portable LED spot that I sometimes bother to move but again it's a spot which can result in shadowing effects.

That's pretty good considering they have a tempered glass front panel, a 3 year warranty, and presumably an earth that works )
The Ali express ones supposedly have a Polycarbonate front cover, but the time a cord, kosher earth connection and plug are added the price will definitely be over the $25 mark - still dirt cheap. I used old computer cords that come with a moulded 3 pin plug. I get these from my son who works for business that replaces their computer cords every 12 months as its cheaper to do that than have them tested and tagged.

Hi Baron, you will be impressed after the surgery if all goes well, I have had both my eyes done, it would the most successful result I have had from any surgery I am in the same boat needing to where glasses except mine are for distance that is how I wanted it as I have been short sighted since I was 17 so it was not a big change.

I have LED tubes for general lighting and as well have the LED 'floods' to throw light in particular directions (I periodically visit lighting shops and check out their outdoor section, as that is where the 240V LED floods normally live). The aim was to get reasonably bright but uniform light in the main work areas. About the only place where I would like more light now is the far side of the mill, but I am yet to find a cheap flood that I can disassemble enough to install a longer cord. I have lights on the mill, but they are pointed at the work area and are 'spot-ish'. Lighting up the shadow would be nice.
The two here are from different shops; one is cool and the other warm, just to try and avoid the operating theatre look. When the shed was first wired, the sparky suggested having some of the light circuit as plug in and I'm glad I did. That way, I can have something like that power board there and switch on/off some of the lights, depending on need. The roof has a polycarb skylight, so on a sunny day I may just have the tubes on but if it is overcast, I have the option for bring the light levels up a bit.

Thanks for the details of the light and where you got it Michael. I'll be at M10 first thing to get a couple of them.
Thanks again,

Hi Guys,
Thank you all for your support and reassurance !
I admit that I'm a little apprehensive, even after having the pre-op examination and discussions with the theatre charge nurse. I'm assured that the operation is totally painless and though I will be immobilised I will still be fully conscious and be able to answer questions.
So I am very appreciative of your comments.Best Regards:
Baron J.

swmbo had the first one done today. No pain some 8 hours later.
She was a bit apprehensive this morning and up til the doc went into room. All my advice to her telling about my 8 operations on left eye including lens implant 50 odd years ago, and how its changed when I had corneal transplant wide awake didnt settle her.
Gets her other one done in 4 weeks.

Hi Eskimo,
Thank you for that info, its good to know that she is pain free.
I was told that before and during the procedure, the eye is continually irrigated with anaesthetic solution. They said the incisions would have sealed within a few hours, and that there should not be any pain. They did say to wear sun glasses for a few days afterwards until my eye became accustomed to the light.
Apparently everything seems to be much brighter after the OP.
I'll let you know how I get on.Best Regards:
Baron J.

They eye is pretty well dilated but I think thats from the anesthetic...but as for brightness it could be that with a nice clean lens it also lets more light reach the retina.
She didnt have to wear sunnies.
