I want to place some spotlights on my GameShow playfiled.My questions are:

1.Can I add additionally two more #555 lamps to one of the lamp circuits(row)
2.Is the connected transistor will stand withouth demage with this two additional lamps?
3.I see that every lamp has a resistor.I think the two additional lamps must have the same resistor too.Is that right?
4.How many lamps I can connect to one row of lapms?
 
the lamps have diodes not resistors...

also if you are adding spot lights why not just add them to the GI circuit instead of the controlled lamp matrix?
 
I add spotlights to my games all the time. Just clip them to a GI socket and you're good to go. I always use LEDs in the spotlights, so I'm not sure if the extra draw is detrimental with a regular bulb....but an LED is safer, and look awesome in spotlights. I'm not an LED fan in general...but in spotlights they're great.
 
Yes you can add them to a GI circuit, I've done this too. I also do spotlights with either an LED, or normal incadescent bulb.

If I ever do one to a controlled lamp matrix, I always use an LED and diode. That's just how I do it and I don't want to over load that circuit. Adding to a controlled lamp matrix can be a little trickier, so I never over do it.
 
Yes,I want to be in GI circuit.So if I understand right I just can continue the trace from the (for example) slingshot lapms(I want to place spotlights on slingshots plastics) and everything will work withouth problem?
I will use regular #555 lamps.

Is this the right metod of connection:

And as I can understand,I don't need to place diod if I use the bulb on GI circuit?If I must use what type must be?Same as GI diods?What is the work of the diod?Is it some kind of protection?

If I want to use LEDs how can I decrease the voltage of LED to 6.3V?LEDs working on 12V probably

Yes you can add a lamp to the GI going to your slingshots. I would not go crazy and add a few, just a couple or so, but that's just me.

The diode is a form of protection, it lets current flow one way only. Other than that, I don't know other forms it protects but don't need a diode with a GI circuit.

You can use a 12 volt LED in a 6.3 volt circuit, of course the LED will not be as bright because you are usng a 6v in a 12v circuit. Not sure if that would give you the results you are looking for though. Probably not... You could use a frosted LED or put a bulb condom on it, or both to make it less bright.

I can't see you pic right now at work for some reason to comment on...

I can see your pic now and yes, that would be correct for the wiring.

Looks to me like it will work fine. FYI: The GI is AC so there is no "ground" like you would have in a DC circuit.

You won't need to add any diodes in this case. Lamps in the lamp matrix will need diodes across them to maintain the matrix but GI will not have diodes across the lamps.

If I want to use LEDs how can I decrease the voltage of LED to 6.3V?LEDs working on 12V probably

Your best bet is to just buy LEDs that are intended for pinball. If you want to use other LEDs you'll need to add a resistor in series with the LED to limit the current. The value of the resistor will depend on the current handling capabilities of the LED and how bright you want it.
 
The diode is a form of protection, it lets current flow one way only. Other than that, I don't know other forms it protects.

You can't decrease the voltage on the GI circuit from 12 to 6 volts, unless you modify the board.

actually pretty sure the GI circuits are AC so a diode would not be a great idea...

also pretty sure the GI circuits are 6.3v not 12
 
As I understand from all comments from here and other forums,that it's not very recommendet to add bulbs to GI.So i will buy LEDs then.Are the LEDs will disperse the light enough like the bulbs,or the leds have even better effect than the bulbs?

Yes, I fully realize both, not sure why I typed that but will delete it now.

My original post also addresses the diode or not.
