Hello all,

Does anyone know the bulb number or voltage of the bulb that goes in the LL mission select pcb?

I've replaced them and they're too bright and hot. Tried some leds and am toasting them one at a time...

Thanks
Tom
 
They're running off the +10V unregulated.

The manual says #1816 lamps.

I couldn't find those locally, so I used #1893 lamps instead.

Tom,

The lamps are in fact #1816 which is what I installed on the Lunar Lander mission select replacement lamp boards. I checked online and it looks like pinballlife.com has them in stock again if you want to go incandescent and only need a few (5).

Bryan over at paradisearcadeshop.com also sells a nice LED replacement which I have installed in my game. I can't recall the part number but I can check this weekend if you are interested.

That would be great Steve - I was hoping to put LED's in the panel. I've tried some as a test and cooked half of them...

Thanks
Tom
 
Tom,

I could not find the LED lamps on paradisearcadeshop.com web site so I fired off an email to support. Susan wrote back and they are temporarily out of stock but should have a large quantity available in a couple of weeks.

If you can't wait and want to use some of those #44 6.3v lamps, you can build an adapter with 9-10 1N4001 diodes in series. I recommend waiting. ;-)

That's the 6.3v version so I would wait the two weeks until paradise arcade has the 12v back in stock. Like I said before, I could not find the led replacement for the 1816 lamp on the web site so I emailed asking.


Just seems like a big step to use diodes in series, perhaps 1 x resistor would be another (perhaps easier) solution :)

You really want to limit voltage (diode) not current (resistor). But hey, if you like heat and lamps that really dim when more than 1 is on, go for the resistor. I suggest a nice fat ceramic model and avoid touching the resistor until it cools. :p

I know what you are saying, I am a sparkie, and LED would be great. So thanks. Might be worth finding a 12V version, so they are plug and play

you could use a ziner diode that will limit the voltage and let the current flow.

Yep, or a 7806 but I don't have 3000+ of either in the storage unit on the bench.

Warm white LEDs? That's what I went with.

BTW Dan, I sold my LL last week to free up some space around here.

I would have bought it... Oh wait I have 3;) Yea I have white LED's in mine too.. Running in my mint new reproduction Light PCB my buddy made for me :)

So did you find a source for them or did you wire up the resistor or diode suggestions?

I have cool whites in mine and have killed 1/2 of them...

Thx
Tom

Got mine from a pinball vender at the Seattle Show, they were the right voltage. I think the best source would be the ones Xray2 mentioned once they get them back in stock..
 
Tom,

Dan is right, you just need to order the right voltage lamps. Changing up the voltage is not really worth doing since the correct voltage lamps are available. If you're desperate you can probably find a warm white 1816 equivalent LED lamp in stock at store on the Internet.

I recommend just waiting for the "right" parts even if you buy a pack in incandescent 1816 lamps to hold you over.
 
TOM,

PM me in 2 weeks with a reminder if you do not locate what you are looking for.
