I am replaceing all of my building lights & street lamps with 5mm led bulbs,all told there'll probably be about 50 to 60 led's,i also have 1, 4 bulb flood light tower & 1,16 bulb double flood light tower & 2 small buildings that will have regular bulbs,my question is how many more led's can the lionel kw power without running into any problems? I don't know anything about amps,or watts or millie amps, i just hope someone can come up with the answer for me. Thanks for your help.

Gerald,
You should be fine using the KW, for your accessories, use both channels and spread the power draw out evenly.

even better.....do a little math; read the instructions for each bulb type or accessory; add them all up and see what the numbers say compared to the fixed volt rated studs on the back of your KW. somewhere on the interweb you'll find a chart to convert all that to a rating. I do the exact same thing with my lighted buildings, and the trolley which runs off the B side.
try it! you may feel more assured that using a little of the ol' grey matter will save you a possible circuit breaker tripping of fire.
Dave,Thanks for the quick response,there are no trains being powered with this transformer,just lights & a few accessories ,the reason i asked this question is that i want to add some more led's to light the entire lower level of the layout,to create a different look,also the led's i am using can be run on full track power,i got them from Model Train Software [ Evan Design] already made up i just have to hook them to a power supply,i still would like to know if possible how many more 5mm led's i can use on this transformer.
The website of Model Train Software says their LED's draw 20 milliamps of current each.
At that rate, you can power close to 500 of their LED's with the KW.

TrainLarry,I was just looking at their web site & i saw what you just posted ,they also say that 1-amp will power 50 led's,so all i have to do is find out how many amps the KW is rated & i will have the answer to my question. I was looking on the transformer for this information but i didn't see it, i will check again & if still can't find it i will check the owners manual & see if the information is there.
Larry,thats the information i needed many thanks for your help,it makes things easier for me.

IMO using a KW to power a layouts lighting is more than you need. It will handle all of your lighting needs and then some. The only drawback is that it will use more electricity than a smaller transformer
