Really, (REALLY) OLDE LAMPS that we used to work with =>10 photos

 I've written about bench-lights before, but nothing like these out-of-date and antiquated lights...WOW & OY!

 

 We must begin to think of OUR EYES. We only have two of them, and they must never give us problems, agree?

 You can see a 'pump drill' on the far right of the bench. These were used on pre-motorised drilling equipment.

 The earliest light source were these candles that were made of wax and had to stay on the workbench.

 This is my bench with my main 'three-bar light' and a side (2-bar light) backup source of light.

  This cute-looking lamp has one problem, which is that it has just one bulb. OUCH!

 The metallic shield covering the 'reflecting bulb' will give anyone eye strain and headaches in minutes.

 My own eyes wouldn't last for an hour due to the glare of that one bulb. You can see that there was a 'light and heat shield' placed in front of that one bulb.

 This three-bar light is still used on my 2nd bench. The pulsating flicker of one bulb is too much for the eye. 

-------------------------------

 This is why some lighting fixtures have three bulbs, as the two remaining bulbs will cancel out each of the 'flickering' effects.

 The 'flickering bulb' pulsates at 1/15th of a second. (I just thought that this might be interesting for you)

 

  I'd give up setting stones in a 'nano-second' if I had to work with these mediocre lamps. (A nanosecond is 1 billionth of a second).

 I have no idea when this lighting fixture was used. But it could have been in the previous century.

 I think that it used kerosene as a lighting source. The half-round bell on top allowed the 'light heat' to dissipate.
