    Gotta catch a plane in a couple of hours, but as promised.....

    Test subject BK2K-
    All Lamps on for the same amount of time.

    Back Box

    Half Incandescent #44, 2 - 55W lamps, Half Frosted #44 LED
    All temperatures recorded in Celsius

    Will post more when I return.

    I'm going to LED out my Fire! when I return. I'm going to take some images of the row/column wires, fuses and driver board before and after for comparisson. Should be interesting.

    #12 11 years ago

    I can post some pics under the LED sticky when I return, going to be awaya from my main rig for awhile.

    #13 11 years ago

    And Haven't forgotten about you Cliffy, Didn't have the time to play a game so the shots of my driver board and fuse holders weren't very good. I'll take some close ups under load soon.

    Quoted from Winball_Pizard:

    The incandescent bulbs in the back box look, scientifically speaking, a bazillion times brighter than the LED's. What happens when you compare two bulbs that are equal candle power or a incandescent bulb vs something brighter like a CT super or something.

    You're right. The difference in lumen output of the left side vs. the right side is huge. This is not an apples to apples comparison really as the right side of the box are actually frosted yellow LED's, they are the only loose LED I had in quantities to be able to do a significant portion of the backbox. I did take a shot with several frosted cool whites that I'd pulled out of my LIS, and although the lumen output seemed comparable, the heat signature was still very much the same as what is pictured in the top set of pics. Honestly, I am a bit of an ubergeek when it comes to this kind of stuff, I actually have a trending light output meter that measures LUX, Lumens and foot candles too, so when I get back we can do some much more clinical testing if we want.

    Quoted from decktard:

    If you have the time at some point... and this might be a little bit of work...
    I'd be curious to see how the same backbox GI connector looks with incandescent vs LED... as this is a source of burned pins with so many machines.
    I specifically put LEDs in my backbox to prevent further issues with the connectors on my board. Although... I did 1/2 of each LED and incandescent.
    Edit: I guess you said you were going to do that on your Fire! a few posts up. Thanks!

    Can do.

    Quoted from Dewey68:

    Cool (no pun intended) pictures! For most home users I don't think incandescent bulbs put enough of a strain on a healthy circuit to do harm, unless you leave them on 12 hours a day. I have a few LED's but I'm not sold on them yet. I like the slower light decay you get from incandescent bulbs, LED's instant on/off seems harsh to my eyes.

    Agreed, I think there are games that look better with the twinkle of standard bulbs, hell, all of the lamps in my house are halogen as I don't like the artificial look of LED's compact fluorescent etc. That said, I'm having a rough time finding plastics for a couple of my games, if the trade off for keeping the plastics I've still got healthy and happy for years to come is a harsher looking light, chances are I'll change 'em out.

    #26 11 years ago

    Thanks for the suggestion, I'll check those out.

    I've never personally had plastics damaged, other that warping and yellowing, but ive seen my fair share of burnt bumper caps. Also, after spending a bunch of time knocking back playfield inserts in my f-14, i gotta figure cooler is better.

    Quoted from sixsixtie:

    Sparky I think you have my old getaway. Confirm or deny?

    I bought mine on the Island a couple years back. Beautiful machine.

    Quoted from sixsixtie:

    Ah cool. Not mine. The guy I sold mine to had a BK as well as two other machines so I though the chances were decent. I think he was from Langley too.

    I think thats my buddy Dave. Great guy, played my Getaway and wanted his own.

    Quoted from putman:

    This is really great. Could you do the PCBs in the backbox? I'd be really interested in seeing where the heat is.
    Thanks!

    Next series. That's where these cameras are awesome in ths hobby. Bad solder joints, bad connectors, oberloaded wires, fuses etc. Thry all show up like lightning bolts.

    Quoted from Cliffy:

    No sweat (get it? but really that's what you want to capture. Good fuse clips vs weak ones. Weak ones should show really hot.

    For sure. The smoking gun pictures that I want to capture will show the fuse warmer on one side than the other. If the fuse is seated well the current should be the same throughout the length of the fuse. Likewise, looking at rows and columns/strobes etc. finding one wire that glows brighter than the other means that it is usually more heavily loaded than its neighbours but not nescessarily a problem.That same wire that glows more brightly at the termination and cools the further it gets from it, thats a bad connection that if not corrected will end up with a burnt connector or worse.
