12 Volt AC transformer to power LED's question

BobbyD ·
Need a few to power about 20 LED's. (Locations may too far apart to run connecting wires.) Any ideas? Need to be really well controlled as I don't want to vaporize any LED's. Is there enough power in the Z4000 14V tap to do this and power a TIU as well? Thanks!!

Lionel Replacement Ditch Light Help Needed

Steims ·
I have a ditch light that is out on my UP AC6000 6-28327. The Lionel part number for a replacement with harness/wires is 6208327387 LED/DITCH LIGHT /AC-6000 / LEGACY. Lionel shows they are unavailable. Anybody know where I can find one? The number on the back of the LED board is 28-A144. I have confirmed I have 5 VDC at the LED terminals.

LED 3 Volt DC Lighting Issues...I'm Stumped & Need Your Help!

Maine Main Line ·
Greetings. I've read as many posts as I could on low voltage lighting and thought I was well prepared for the task at hand, but apparently even my electrical wiring expertise has left me clueless! I purchased some LED 3 volt lampposts to add some nice finishing touches on my layout from a vendor from China on eBay. After having issues just getting replacement light bulbs for my Lionel station platforms, I figured I would go to the much more realistic, and hopefully reliable, LED lighting.

O- Gauge, battery powered lighting kits

Mike Wyatt ·
I wanted no-flicker lighting in my Lionel Aluminum Congressional cars. After looking for a way- I happened upon "Dr. Bob's" kits- he sells a variety of kits that are marketed (mostly) for the smaller scales- N, HO, and (some) O. I bought the S/O constant lighting kit. Not being an electronic guru- and since Radio Shack is no longer available to me- buying such a kit was better for me. I was sold fully after I saw what the kits included. In the envelope, each kit includes great instructions,...

The RR Track Signal Control Board Project

gunrunnerjohn ·
Discussions keep coming up about a signal control board, especially now that there seems to be several choices for cheap O-gauge track signals. That being the case, I figured we'd start a new thread and see what features might be desirable in something that would be in kit form for users to build. I'm thinking we'd sort out a feature list and then whittle it down so that it could be made in an inexpensive manner with common parts. I'll start with a few attributes and we'll go from there.

Hi guys, I recently did a project and put LED lights in some of my O scale automobiles. I would like to offer my services to put LED headlights in your O scale automobiles for $10/car. All you have to do is send me the car, I will install the lights, and you just have to plug it in! The way I am powering my cars is through USB. I made an adapter board that takes 14-18 VAC and converts it to a safe voltage of 4VDC. This system will allow you to connect USB hubs to split the power into...

2mm LED source and marker light LEDs (for upgrades and repairs)

NBGT ·
Does anyone have a good source for 2mm diameter LEDs in a through hole, round base, dome top format? There seem to be limitless supplies of 3mm LEDs in this format for pennies each. I've only found a few 2mm LEDs and these have been over $1 each. Alternatively, what are good LEDs for marker lights? Thanks!

Team, i have the 2011 Lionel 18 inch Milwaukee Road 7 car passenger set from 2011 that I never opened until today. Half of the cars will light up and the other half don’t. I stored them in my attic which might be the reason they don’t work. I have the correct replacement bulbs, and replaced them on the one coach and they still don’t light so I am thinking that the board in the roof is not good or the on / off switch on the bottom of the car is bad.

Super Chuffer Headlight Circuit

NBGT ·
Hello, I’m installing a Super Chuffer and I’d like to drive two green LED marker lights off the headlight circuit along with the headlight. The super chuffer instructions say the circuit is rated for one white LED at 3V. I’m curious to know if this circuit could handle the extra load of two 2mm green LEDs wired in parallel with one warm white 3mm led? Would any resistors in series be needed to limit the current? Thank you!

LED refresher

rrman ·
I was examining an Atlas CPL signal and best as I can determine without taking it apart destructively, is that the two red LEDs anodes are wired in parallel to its red power wire, two paralleled yellows to its yellow wire, ditto for greens. All LED cathodes are grounded to signal frame. From what I remember in school or reading online, if LEDS are paralleled, the one with the lower Vf will light and the other may or may not, or lights dimmed. Yet these LEDs shine with apparent equal...

Re: Adding LED on PS3 locomotive

gunrunnerjohn ·
I would not tap off the headlight for the firebox glow. First off, different LEDs have different operating voltages, so trying to run dissimilar LEDs in parallel is an exercise in futility. The headlight drive is also current limited, so adding loads will create different issues as well. I suggest you run from track power with a 22uh choke, diode, 220uf 35V capacitor, and current limiting resistors. I'm somewhat surprised that the red LED and the flickering LED's are working in parallel, the...

Re: Adding LED on PS3 locomotive

Ok. I did see your posts on the other threads and have the components all set up. I believe the 3mm red LED is 5v. What would the circuit look like if I have that added into the mix? I have the LEDs already CAed to some plastic. Could I run the red LED in parellel and just add a 100ohm resistor in series with the LED on the positive side, John?

Re: Adding LED on PS3 locomotive

Corsair2002 ·
Also, based on your circuit diagrams running off of track power, if the LEDs are 3V (red one is too) and the track voltage is 18V, and the LEDs are 25mA, if the three were in parallel that would be 75mA. Doing the math, would it be 18V-3V= 15V. Divide that by .075 amps, you get 200 ohms. Or do I have to take into account the capacitor at all? Would that work for the resistor after the diode, and then if the red LED is too bright, just put a 100ohm on the positive side just before the red LED...

Re: Adding LED on PS3 locomotive

gunrunnerjohn ·
Actually, common LED are maxed out at 20ma, and you don't really need that much current to light them properly. Also, when you have 18V on the track, the capacitor charges to the peak voltage, so you'll have around 13 volts maximum after the filter. I'd suggest a 470 ohm 1/2W resistor for the two flickering LED's in parallel, and I'd go a separate 1K resistor for the red LED. I think you'll find they look pretty good at those levels. Here's an example...

Re: LED room lights

brwebster ·
I built the room with LED's as a main lighting source. I never took into consideration how they might highlight boo boos when applied as an after thought. Luckily you chose the type that is dimmable. Hopefully for all of us, their claim of longevity comes true....payback for the initial cost. Otherwise, the type I chose ( replacements for conventional pot lights ) give me the best light I can possibly imagine. Perfect for detailed work using these old far sighted eyes. Bruce

I only buy the 3000K bulbs. I find the 2700K too yellow and the 5000K too white. By the way, I am using LED GU10 track lights and when I installed a scale speed sensor system to display scale speed of the moving trains, I found that I had to replace one of the LED track lights with an incandescent bulb. It seems the LED light was somewhat invisible to these particular light sensing diodes.

I have a sea of spots in various rooms in my house, my solution was to leave one incandescent bulb in the controlled set to provide the resistive load that the dimmer requires. It works fine that way, but if I use all LED's, they do indeed flicker. I use the X10 remote controlled dimmers.

CACHOW, If you are talking about the old 022 Lionel Switches, when I used my 711/072 switches, which take the exact same bulbs, I purchased mine from Town & Country Hobbies and Train Electric LLC, they have both the Bayonet and the Screw in type replacement LED's, and yes you can simply replace the old bulbs with them. Remember to replace the track side Switch Bulb also. PCRR/Dave

We have 4000 kelvin dimmable R-40's in our kitchen. I know it is not a train room, however when the lights are dimmed the color rendering stays very true, just not as bright. We have 5000 K in our bed room and if it were me I would try the 4000 as suggested above.

RRMan, Lutron makes a nice dimmer specifically for LED dimmable bulbs. I have the 5000k Par 30, 65w. I find them harsh at full brightness. I do like them at less than full brightness. Still good detail (oops will show), but not like a clear summer day. I believe a mix of the temperatures will provide the result that you want. I do prefer the daylight over the warm white for the layout lighting.

No, Leds do not emit UV or IR radiation.

LEDs do not emit UV or IR radiation and the light does not generate heat (although the conductor box does). They can supply light for a lower energy cost and have a longer...

Showing color temperature ignorance, the bulbs I am looking at come as either 3000* or 6000*K, so if I were to alternate bulbs would the blended light in effect hit somewhere around 4500-5000*K, or would there be noticeable yellowish and bluish spots on layout? I know incandescents radiate other color temperatures around the designed one, while LED are monochromatic with no other radiated temperatures.

I run 4100K LED bulbs (48) in the high hats in my train room. 5000k was too 'blue' and 2700k was too warm. I use a Lutron dimming system which works well. I will say that when you dim the bulbs to a certain point you get a noticeable flicker which can be annoying but nevertheless there is still plenty of acceptable dimming range. The bulbs are 12 watt bulbs which are comparable to 85 incandescent. They give off no heat. dick

Although it may look good to your eye, unless it's a homogeneous color blend, your camera will not be able to reproduce accurate colors. Many modelers have used a combination of incandescent and fluorescent lights because they like the look. However, when doing photography you shouldn't mix color temperatures. If you set the white balance for one color temperature, the areas that are being lit by the other temperature will be off. If you put your white balance between the 2 then all colors...
