Amount of lighting
Concerned that I was getting lazy, I went out and measured my ceiling
joists and other structure carefully and spent my evening with SketchUp! I am concerned as to how many new 48" (10" wraparound) fixtures to add. Please see my two jpeg's: http://web.newsguy.com/MySite/ Putting another light above my virtual bench may make good sense. However, If I regard my bench area as 10' by 8', then my new pics at my web site already demonstrate 80 ft^2/6 bulbs = 13.3 ft^2 per bulb! Don't want to blast my self out. I was thinking of using 32W, 5000K or 6000K fluorescent bulbs. I would like to try to optimize my lighting? As drawn, the distances of the lights from the walls are 36" and 24" respectively. Assume the walls will be white (for decent reflectivity). The floor is concrete. I'm going to keep the light in front of the subpanel 36" away from it to satisfy relevant codes (regarding a "free workspace"). I never did this before and I hope to do it right the first time. What would you change? Thanks, Bill |

Assume the walls will be white (for decent reflectivity). The floor is concrete. I'm going to keep the light in front of the subpanel 36" away from it to satisfy relevant codes (regarding a "free workspace"). There should be a light positioned to illuminate the guts of the panel-- for some reason I was under the impression that there was a code requirement for that but it might be my mind playing tricks on me. The "free workspace" requirement doesn't mean there can't be anything in the ceiling--the idea is that there has to be room for a guy working on the panel to stand in front of it and work on it without being in an awkward posture. I never did this before and I hope to do it right the first time. What would you change? Just a suggestion but check your local library and see if they have or can get for you either the "IES Lighting Handbook" or "Time Saver Standards for Architectural Design", or check the used book sites and see if you can find older copies for cheap. "Time Saver Standards for Architectural Design" has a good section on lighting design, with illumination patterns for many common types of fixture, the required illumination levels for a wide range of tasks, and details of calculation methods. The IES Handbook has that and a tremendous lot more--it's the "bible" of the lighting industry. If you're dealing with straight tube fluorescents then any edition of either published in the last 30 years or so should have what you need. If I have time over the weekend and can find my copy of Time Saver Standards I'll see if I can work out the numbers for you, but no promises. |

Not as much use if the shop is cold and the florescent lights take a long time to come to full brightness. The light for the tablesaw should be high-frequency ballast and/or include at least one incandescent (often a spot pointed at the blade) that does not "flicker", to avoid the "strobe effect" where the blade seems to stand still as it slows down (while still spinning.) People go with all sorts of options, and work under all sorts of conditions. As you get older, you'll want more light to maintain acuity as your eyes go to crap, unless you got really lucky in the eye lottery. "Blasting yourself out" is almost impossible, given the amount of light in full sun .vs. what we achieve with any indoor lighting. Providing appropriate light for the task at hand is more like it (ie, if you are not doing any fiddly work away from bench or machines, less light is appropriate there, particularly if it's something like lumber storage - OTOH, if you are finishing large projects away from the bench, you'll want lights you can turn on for that process, at least.) If you have any "shop lights" around the house, they are easy to hang and move and get an idea of where you are putting permanent fixtures. Sometimes real life is better than any computer model you can reasonably expect to find for free. Paint the floor white. It won't stay pristine white, but it will reflect more light than a gray or red floor, and paint keeps the concrete dust down. This is what - 20 x 25 x 8 ft high? I'd guesstimate that you'd want at least 6 fixtures for general work lighting, and more on the bench. -- Cats, coffee, chocolate...vices to live by |

I am concerned as to how many new 48" (10" wraparound) fixtures to add. Are you -sure- you want wraparound covers (which are VERY good collectors of dust) in your shop? And 9 (or 12 if you put in the extra switching for them.) Please see my two jpeg's: http://web.newsguy.com/MySite/ Putting another light above my virtual bench may make good sense.

I was thinking of using 32W, 5000K or 6000K fluorescent bulbs. The 5000K have a better CRI, but either is good in the shop. Check the lumen output of the bulbs, too. They vary widely between brands. I would like to try to optimize my lighting? As drawn, the distances of the lights from the walls are 36" and 24" respectively. Assume the walls will be white (for decent reflectivity). The floor is concrete. I'm going to keep the light in front of the subpanel 36" away from it to satisfy relevant codes (regarding a "free workspace"). My take on the NEC code leads me to define the workspace as the area which extends from the top of the panel (or 6'6" min) to the floor, and allowing a (large) person to get right up to the panel from the front. I wouldn't build anything within a foot of either side of the panel, but I wouldn't hesitate to roll something movable (router station, unplugged welder?) into the access space. I don't read the code as mentioning overhead access, but. What (as I suggested earlier) did your local code inspector say about it? He's "god" for all things electrical in your area and what any of us thinks has no meaning there if he says something different. I never did this before and I hope to do it right the first time. What would you change? Do yourself a favor and do temporary hangings of the lights to see for yourself what light level you're comfortable with. _Then_ hang and wire them permanently. I'd hang them the other direction, 3 per column in 3 columns, 4' between bulbs either way, centered in the room. (Lew would probably want them every 2' for a total of 40 fixtures or so. Get checked for cataracts, Lew! Lew's scenario would blow you out of the shop, requiring #5 welding goggles to see through the glare. ;) Task lighting on each machine (where required) and over the benches (if necessary) will fill in the gaps. P.S: I forgot to ask if you put quad outlets everywhere. There's always a third cord to go in whatever outlet you're near, y'know. -- Happiness comes of the capacity to feel deeply, to enjoy simply, to think freely, to risk life, to be needed. -- Storm Jameson |

Try to keep your bench lighting between you and the wall to prevent shadows when leaning over your work. That's a really good thought. Thank you. That may be a good argument for an additional light "between me and the wall". Bill |

You don't need to worry about your shop lights being inside of the 36" workspace around your panel. That workspace defines unobstructed floor and wall space. That's helpful. Thank you. I thought I read "36" in front of ...and up to the ceiling", but a light snug to the ceiling is not really an obstruction (to me and you). I'll double-check. Bill |

Nice drawing using skethup. Where did you get the bandsaw ,workbench and
tablesaw? Did you make them yourself or download a library? As far as lights, I agree with quartering your layout. I have boxes that have 3 bulbs. I put four in my hand tool area, None directly over the bench. I put them offset to both sides .. to eliminate shadows. I also use swing lights on all my benches. I find it more helpful to have direct light where I need it. I find these at garage sales and fix them up. Sometimes you get a brand new one for $1... All my tools have mounts.. My sanding station, router table, workbench, sanders, scroll saw, I try to avoid direct overhead lighting knowing my head will block out the light when bending over. My tablesaw has 2 overhead boxes, one on each side of the blade and toward the outfeed table to avoid my own shadow.

Walls and ceiling are all painted white. In addition there's a 100W incandescent spot in an adjustable fitting aimed at my vice. The other end of the bench there's a large circular, illuminated, magnifying lamp on an "anglepoise" type arrangement. Apart from it's use when critical marking out (metalwork mainly) when raised up it can provide more general "Task lighting". This has a "G" clamp like fixing and can be moved from its present position, clamped to the end of the bench towards the back. Fixed to the underside of the 12" wide shelf, which runs the full length of the wall, over the bench, at this same end of the bench, is a 20W halogen spotlight in an adjustable fitting. This can either be positioned to throw light forward onto the end of the bench or swivelled through 90 deg to direct light onto my X1 milling machine. If I turn round from facing my bench, I find myself facing my C3 minilathe against the other wall, which has a 60W incandescent spotlight in an anglepoise fitting clamped to the tailstock end of its bench. This lamp, when rotated through 180 deg will throw additional light on my router table. In addition to all this I have a 60W incandescent spot in a "lead lamp". This has a strong spring clip and can be used anywhere in the shop, though it is normally positioned to aim light at the table of my drill press - which is next to my mill and also throws some light on that. In your situation, I'd certainly be adding a lot more 4ft fluorescents I enjoyed the "tour" of your shop! From your post, and others, it's apparent that "systems" of lighting evolve. I don't want to be an energy hog, so I'd prefer lighting systems that I can use in a discretionary way (compared to ::INSTANT-ON::). I think I'll begin by illuminating what I regard as the main part of my work area and take it from there. I intend to power the lights using ordinary plugs into new 2 duplex outlets (which will be subservient to 1 wall switch), so my configuration will be reasonably adjustable. Some of my virtual furnishings (i.e. cabinet and workbenches) are waiting to be built! It wasn't until today did I really thought of lighting *systems* as such. At some point though, one has to make a few trade-offs to get some work done! :) No doubt, there are more systems ahead (DC, HVLP, plumbing, ...). Using Hemmingway's words, I just want "a clean well-lighted place...". :) I'm glad to see that my h.s. literature class is finally paying a dividend! Bill |

I downloaded the drillpress, bandsaw and tablesaw models from the SketchUP 3D Warehouse. I modeled the benches after looking at a design published by FWW which was presented by Garrett Hack in "Tools & Shops" (Winter 2009). His bench also has a tool-trough, and other niceties. I downloaded the vises from 3D Warehouse. As far as lights, I agree with quartering your layout. I have boxes that have 3 bulbs. I put four in my hand tool area, None directly over the bench. I put them offset to both sides .. to eliminate shadows. Hmm...At this point I was thinking of putting ceiling lights in front of me and behind me, to eliminate shadows. Same idea? Perhaps I would be wasting light illuminating the wall. I will think more about "quartering" my layout, but I have a garage door over 1/3 of the space (up to the existing lights), an overhead access door, and a "medium traffic route" used to help unload groceries, that doesn't require further illumination. Your comments below about direct lighting are well-taken. Thanks, Bill I also use swing lights on all my benches. I find it more helpful to have direct light where I need it.

Mine is 20'x 24' too. Almost exactly 1/2 of the ceiling is basically occupied by the electric "garage door". Although putting lights above it may be possible, I am not interested in considering it at this time. I'll do some more modeling in a few days based upon recent input folks have generously provided to me. Good thoughtful comments on the task lighting above. Not exactly sure how to take them into consideration, but doing so seems like the right thing to do. Still homework to do on this..more modeling. One good thing that is the price of my fixtures may have went down since I set aside the deluxe wrap-arounds so I should be able to buy a few more. Bill |

I don't want to be an energy hog, so I'd prefer lighting systems that I can use in a discretionary way (compared to ::INSTANT-ON::). Well, in my case, only the fluorescents are normally switched on, all the other lights have individual, local, switches and are used as and when needed. The two fixed spotlights I mentioned are ultimately controlled by the main lighting switch but the anglepoise lamps are all plugged into wall sockets. I think I'll begin by illuminating what I regard as the main part of my work area and take it from there. I intend to power the lights using ordinary plugs into new 2 duplex outlets (which will be subservient to 1 wall switch), so my configuration will be reasonably adjustable. Ah yes, outlets, you'll need lots of those - always more than you think. In addition to the ones round the wall I have several fixed to the ceiling down the centre which are useful for portable power tools. If you can reach them, these would be useful in your situation as you have a bigger area to cover and parts would be further from the wall requiring long leads which you could trip over. -- Stuart Winsor Midland RISC OS show - Sat July 9th 2011 |

And I have to tell her that I need a drill press, band saw, table saw, router, fluorescent and task lighting, and new electrical sub-panel panel to make this birdhouse. That is trickier, as I understand it from a bachelor's point of view. Reminds me of the cute story that ends with the question: How much did it cost you to make that little table (birdhouse)? $100k. : ) Sounds about right. My numbers are smaller of course, but it still makes me smile. One would hope. Another antique metal-cutting lathe showed up at the local auction this week. More petite than the monster that showed up a few months ago. I'm either becoming more particular or becoming a conniseur. It's cheaper and easier to be a conniseur than a collector! :) Indeed! -- Happiness is not a station you arrive at, but a manner of traveling. -- Margaret Lee Runbeck |

Just Do It! -- Happiness is not a station you arrive at, but a manner of traveling. -- Margaret Lee Runbeck Typical garage door needs a significant amount of clearance from the ceiling - there should be plenty of room for lights there - climb up a ladder and measure it. You can also mount them on the garage door tracks if you are capable of a little metalwork and pay attention to where you can attach stuff without mucking up door operation. Those would not be blocked by the door (but they will be its full width apart.) Fairly rare for most of us to have lights on and door open at same time, in practice (even if the weather is nice, the bugs fly into the lights, and garage-door-size screen doors are a significant hassle/project.) -- Cats, coffee, chocolate...vices to live by |

It's just that getting electricity to that precise spot isn't as simple as it may seem on the Internet! : ) Unfortunately, I think even a good description of the mess involved would pale in comparison to the actual mess... Maybe there is an easier way...I need to investigate further and see. Bill -- Happiness is not a station you arrive at, but a manner of traveling. -- Margaret Lee Runbeck |

It doesn't look all that sexy. But is is often done in shops. Not much mess with that approach. Just find the wood behind the drywall to attach the conduit. Conduit attaches easily to the outlet boxes. Lights and outlets can them be added to the outlet boxes. |
