I am upgrading old locos with ESU decoders, some locos are analog some are deltas. A friend told me that their old bulbs are 19V, 0.8A, thus must be replaced with the digital kind.
He says the old bulbs will melt loco plastic casing and could destroy decoders.
On the contrary my dealer says it is SAFE for digital.
The old bulbs i read from the locos manual are : #610040 (2-pin); 610080 (2-pin); 60015 (bayonet); 600100 (screw).
1. Can someone clear up this confusion?
2. What are the marklin part number for digital bulbs for 2-pin, bayonet & screw type respectively?

Thanks.
I use C track, CS

And,
it's better to use 2 pin lamps, grounded at the decoder, than to use screw/bayonnets that are grounded in the socket/loco chassis. The latter works, but the lamps will flicker.

Do they also make these in red? I am planning to digitize my ICE and would need both red and white.

I sometimes even use a 28 Volt bulb, to reduce light intencity, heat and power consumption.

A perfect type/size is called T1. I buy the ones with long (approx 30 mm) wire ends.

I have some red bulbs, Mark, but they have the same size and shape as the old white 600080. They work perfect with a serial resistor. Maybe 270 Ohms. I do not find the spare part number right now.
What about LEDs?

Hendro, I think the socket is part no 276770. The Lokshop, www.lokshop.de should have them. Closer to home, I know my dealer at www.toottoot.co.nz will also have them.

I've never used these sockets, but I believe they screw into the existing lamp holder.

Someone told me that is always better to replace bulbs with 22V ones, even when you can dim the voltage, because of the bigger current required by analog bulbs, but I don't know it this is true.

Anyhow, I often replace lightbulbs with LEDs when digitalizing a model. This is very easy for locos with 610080 bulbs because I simply insert a 3mm LED in the socket, only adding 1Kohm resistor.
The only problem is on colours, because warmwhite LEDs are not easy to find, but I don't dislike yellow ones.

nice picture Svein
I will probably use such an adpator plus LED plus a dab of paint for the right colour

Dale, this is a good idea . But wich kind of paint you suggest?

The great knowledge that some members have with all these seems
unbelievable to me.Anyway congratulations to the members whom with
their great knowledge help all the others.

As I recently purchased several LokPilot V 3.0 decoders and have magnents on order this issue of light bulbs concerned me. Especially from protecting the decoder point of view. I did a little research and found Kenneth Pallund's web page www.pallund.dk. He had done a review of the LokPilot V 1.0 and expressed concerns about the max output for each light of mA 140. When I looked at the documentation that came with my V 3.0's I found the included docs were for V 2.0 - they have not published the English version yet. The V 2.0 is now rated at mA 180. I contacted Kenneth and he felt that this dismissed any concern about the lighting as he feels the old light draw somewhere between 50 to 100 mA. He later contacted me after looking at the German documentation for the V 3.0 and told me that the max is now at 250mA which I confirmed by looking myself.With this decoder there doesn't seem to be an issue.I am not an electrical engineer but Kenneth is. I hope I got this right so its my fault if I did not, not his.

I use cheap acrylic paint.
