  1. Our new router

    my 30-year-old ESAB is still running, but on control #3 - and we mostly use our waterjet.
  2. Prismatic Letters Source

    alas - they don't make them small enough.
  3. Looking for a source for 3-1/4" high bronze/brass or steel Prismatic Letters
  4. Thanks for the video - so essentially a constant voltage LED module has an on-board switching regulator ? And if you just powered the constant voltage LED with your power supply - you would see the current go up when the voltage went down.
  5. Cleveland clock

    A four hole mount might be a Hansen movement - available here http://www.american-time.com/products-by-family/clock-parts-and-repairs/motors-movements/synchron-type-c-electric-movements if the clock was any larger - my firm www.electrictime.com which makes larger clocks could help you. You may also want to try the NAWCC forum http://mb.nawcc.org/forumdisplay.php?20-Electric-Horology My suspicion is someone stuck a clock movement from an imported UK clock - on this US clock and even if you used a step up transformer - it wouldn't work - the clock would run 6/5 (60HZ/50HZ) fast. BTW - if you intend to throw out the clock movement - I would take it (and pay for shipping).
  6. Cleveland clock

    If the nameplate is correct - the clock won't work in the USA - 220Volts - 50HZ is not the power standard in the USA. I would assume the same about the neon transformer - clock must have been made for export. Reading a little about the "Bichronous motor" looks like it was made in around the time of the depression.
  7. GE vs AgiLight

    Read a bit of the patent suit - I thought a patent was supposed to be "novel" - nothing seems to be novel to me. Same thing with software patents.
  8. MET Laboratories UL48 Program???

    Not to get into the UL/MET/ETL debate - but "CE" is not a valid listing in the USA. It is a self-certified European standard, Electrical Inspectors (and you) should not accept it.
  9. Attempted Suicide - ELECTROCUTION

    Typically when something is attached to building you cannot remove it.
  10. I need (8) GEWWB1P2 – Tetra Edgestrip 3200K - must be this exact color temperature and part number. I'm hoping someone has an open box. .
  11. EGL and LED - WOW

    With a plastic case around it - not a bad idea :) Just 6500K (a bit too blue) but other color temperatures on the way.
  12. To Cheap to pay for service call...

    In the first photograph, is he typing off the ladder - or holding on for dear life.
  13. "only 5 people post" - a challenge

    I'm here from Boston Massachusetts. BTW, the Ballast and Lamp manufacturers pay attention to this board. Post something and you will get a call.
  14. yes - each tube is on separate magnetic ballast - most common thing everywhere else in the world. The results are monitored by an outside company that has some pretty advanced power monitoring products that cost the end customer around $3500 per month to evaluate changes and they confirm their is an 80 Watt to 48 Watt reduction - they also show that light output on the LED system was 30-40% higher. The company that does the monitoring has a few large customers like the largest banks in the southern hemisphere, etc - they are known for dramatically reducing people's power bills. Our kits are also being used by two very large global companies that have shown the same results....one of them is the Catholic Church and the other is the largest dairy company in the world that produces 1/3rd of the worlds milk. And so what are you seeing different in your results Erik? Please do share because your tutorial does not show actual results of light output, power, etc. And please note that our power supplies are not power factored so it may give you an erroneous reading on your power meter...this is very common. I haven't gotten to the light output yet, but power is there. http://www.thesignsyndicate.com/forums/index.php?/tutorials/article/27-project-facilities-fluorescent-led-fixtures/ I'll be posting the video shots soon. I'll be the cranky old guy New fluorescent fixtures lamp life 30K LED lamp life 50K So if your LED lamps last 10 years - the fluorescent lamps last 6 years Can't tell from the Video the quality of the LED lighting, but I not sold on the quality of the LED lighting in an office environment. Any CRI figures or color temperature? To be fair Just saw an application in a beer color with LED fixtures - this is a great application.
  15. WTF Seriously????

    Just ran the figures on a installation, using LEDs vs HO lamps - found aprox 58% energy savings. BUT Neon would be very close to the LED energy use and would last longer. I think most LED's are rated at 50K hours - I find neon can go 100K+ BTW, we have found with B/W acrylic it's best to use lighting that is more on the "Blue" side.
