    Using the image that Art posted as a guide (with some liberty, because I don't know that lamp's exact measurements) and also the image with the lit lamps inside the Perspex block (Slave I cockpit scene) I managed to get a fair value for the lamp's length, somewhere between 9-10mm:

    But sadly I couldn't find something that is close to the one Art posted and in lack of the 'correct' GoW lamps we should stick to the available lamps on the net.

    It is a little confusing based on the fact that the glass tube has a bit of a tail, but I would say 8mm X 2mm is pretty darn close. If you count the little tail piece of the glass you would be close to 9mm.

    Yeah, I noticed the tail and my measurement included that part too. Thanks for clarifying the correct values!

    Is Perspex different than plexi-glass?

    Lights... Lights?

    ...Christmas lights!

    This is a 4mm diameter and 10mm long light bulb used for Christmas light installation. The light bulb gets its power from a AC/DC adapter with adjustable values from 3V to 12V and the current value is set to 12V.

    The RF casing is made from 2mm cardboard (an older work of mine) and the lamps are fitted with double sided adhesive tape (I know, I will need it at one point). The wires are temporarily attached between them in the following manner: the first wire of the first lamp is left open, then the other wire is twisted with the first wire of the second lamp (it doesn't matter which wire), then the second wire of the second lamp is twisted with the first wire of the third lamp and the other wire is left open to be later attached to the power source (in this case the AC/DC adapter).
    The bulbs are powered with 12V and the intensity is not as good as the single bulb had but might work with a real Perspex block. I know these are wrong bulbs, but are a cheap variant and I wanted to see and post a first test of these lights.

    Thoughts?

    Came across some 2mm x 6.5mm dolls house lights, I think used for candles, not sure if they flicker or not though!

    It is possible that these small lights to not work too well, and when I say small, I'm referring to the length not being long enough. I did a test 'Perspex block' by sandwiching 6 piece of transparent PVC sheets with a 1.5mm thickness, but not before I cut 3 stripes in 2 of the 6 sheets, so when I put all the sheets together, these cuts formed a channel for the Christmas lights (or GoW lights). I also found a 3mm diameter and 7mm long lamp on another Xmas light installation. And I forget to mention that you need to scratch off the paint on the lamp bulb with a cutter or hobby knife, so you will have your own transparent lamp.

    The RF casing this time is my new version 'painted' with a black marker while the reflector material is a piece of baking aluminum foil.

    I did some testing at 12V with the 'new' lights by first pushing the lights deep into the block and then I positioned the lights at the opening of the channels. The viewfinder is also a scratch build piece.

    The result is not what I was expecting. But I said to myself that I need to try it with a lower voltage, so I did it with 3V then with 4.5V:

    Kind of disappointing... We definitely need those longer lamps (2mm X 10mm) to replicate the long light seen inside the ESB Rangefinder in the Slave I cockpit scene. The hunt continues...

    What about LED light pipes? I know it's not movie accurate, but they would disperse the light better, just a thought.

    Maybe these could fit? Lionel Replacement Light Bulbs (4th item from the bottom), the "long clear" version. Says they are 1/8" in diameter and 12 volts.

    That looks great but the diameter is 3mm and we need around 2mm for the ESB and around 1-1.5mm for the ROTJ. It might be a great replacement in lack of accurate lamps. Thanks for posting!

    I found a LED light pipe with 3mm diameter and 50mm long 'pipes', but the problem is again the diameter:

    Another one is called Flex System with THT LED's and it has the correct 2mm diameter flexible light guide and this might work as a replacement (see PDF file for product data sheet):

    Hm, I must have missed that spec. But yeah, 7 mm is pretty good.

    It don't say the length, I get the 7mm by reducing the image to a 2mm diameter bulb.

    I think if laser pointers were around during ESB, Lucas would have thrown one in that view finder. how cool would that be?

    This post is not exactly an update, but more like a show off of a beautiful piece I received today from Garrett (terminal fettler - thanks again!), more exactly an exact replica of the ESB Hero Perspex lens block and Polaroid Viewfinder (the RF casing is my cardboard replica):

    I have no words to praise the craftsmanship involved in these pieces, especially that these are so tiny and I highly recommend them for anyone who strive for accuracy (the images don't do justice for them). It has the correct inner channels, the metal foil (or sheet) glued to the bottom of the block, which is made with 2 separate pieces glued together. We just need to find the correct GoW lamps and made them light up!

    And for fun I did the ROTJ Perspex block 'replica' by inserting 3 piece of green elastic (didn't find wires with green isolation):

    Raf, how does the TF rf compare size wise with the Asok rf? Right now I'm designing a self contained led board for the Asok rf and would like to know if it would fit in a TF one.
