Panelboard Lamps

[2021]

I'm getting ready to build the first of several panelboards. I would like information on the type of lamps to use (grain-of -wheat, 2.4 mm?) and more importantly how to mount them in the panel. I've seen some use 5 mm bulbs with a mounting holder but wonder what other methods have been used. Any suggestions will be appreciated including concerns over brightness.
Thanks, Ron K.

I would suggest using LEDs. You can drill holes in the panel and stick the LED in place with epoxy, ACC, or silicone caulk. They are available in a bunch of color choices, use very little current, and last (practically) forever. You can get ones that change color, depending on the polarity of the applied voltage.
(Remember: you've GOT to put a resistor in series with EACH LED. SDmall price to pay for all the advantages...

I agree that LEDs are the way to go. I used lamps for years until I decided to redo part of my control panel and used LEDs. I'm very happy with the results. This photo doesn't show the color well as I used a flash, but the color is much better and easier to see at a glance.

Depending on the thickness of your panel, Radio Shack has handly little black bezels for LEDs There are also other varieties available from a real electronics supply house like Mouser .
The RS ones fit a 1/4" hole, you press the bezel in from the front, and then they take a 5mm LED you push in from the back. Makes a very neat and finished appearance.

I use bi-color LEDs and if you're using Tortoise machines all you need to do is run them in series with the motor leads and you have automatic red/green turnout indication. I started using some of the R-S bezels but they started costing more than the LEDs. If you drill the right size hole (I forget the size now) you can just pu***hem in from the back. I use 2 gang blank outlet cover plates that are made of lexan (advertised as "unbreakable") since they are a little flexible they will hold the LED snugly and they're easy to drill with no cracking. This way I have "mini panels" on the fascia and they look neat.

All Electronics has 2 piece LED bezels at 10 for $1.20 here:

As noted, they are not essential, but you may like the appearance.

Thanks for the replies. LED's are the way to go. I appreciate the advice and will build accordingly.
