    It amazes me as to the increased popularity of these new little guys. I was just browsing another board and now the HO guys have discovered white LED's. Just think, a couple of months ago, people thought I wuz nuts!

    Although I'm not in a hurry to replace all my yellow LED's, I do like the new white ones! Man they are bright!

    Just got my Kato Snoot Nose with the white LED. Yes they are very bright and look good. There is, unfortunately, a bit too much blue tinge to the light. Perhaps the manufacturers will figure out a way to get rid of this.

    I would love to do all LEDs, but there are 2 things stopping me.

    #1) Price
    #2) Lighting effects on DCC don't work as well with LEDs

    That is about it

    Happy Railroading!!

    I have been using them for a while too, and discovered a few tricks.

    1) Filters...use a Gel Wratten #85 filter to correct the color from bluish to incandescent white.
    2) Use an extra 470 ohm resistor in series with the LED to drop the intensity instead of using rule 17 with DCC...they cause the transistor on the decoder to generate less heat too!
    3) Sand the led lens flat on the front and the light will collimate to a more prototypical headlight.
    4) You can use the LED at full brightness and it will illuminate numberboards you make from your inkjet printer, and they look fantastic!, just brush a little flat black paint inside the shell so it don't glow on you.
    5) Drill small holes in the LED lens (not so far as to touch the chip)the size of your fiber optic cable class and ditch lights, and super glue the ends in the led. dab flat black on the over your new opticpus to seal the deal.

    Anymore tricks? Post them here!

    Robert, how do you make number boards on an inkjet printer? i.e. what do you print them on? Printing on decal film does not work, and I would really love to do this, as making up number boards with those tiny individual decal numbers is a real pain [​IMG]

    BTW I will try your tip #5, much easier than trying to align the end of the fibre optic with the led!

    I just use paint shop pro to reduce the image size, making several reductions of various close sizes. I print on an HP 812C printer and use #96 brightness inkjet paper!

    What I end up with is a couple rows of the numbers I want, in several close sizes. I move the paper over a light bulb for a few minutes to dry the ink, then use an exacto and straight edge to cut strips of the numbers. when making the white numbers on black, I use a sharpe' marker to blacken the edges of the number board, hiding the white of the paper. Don't try to countersink the

    DOn't forget, plain old paper was the craftsmans favorite choice of construction material in days past, and is still a perfect medium for n-scale modelers today!

    Dane, you said the price and FX effects are preventing you from changing to white LED's. THe price is $2.77 for 10 or more & the MARS/Gyralite effect looks pretty good to me. I don't have any decoders with bulbs installed so I can't compare LED to bulbs.
