Tony Davis Posted October 1, 2020 Share Posted October 1, 2020 Am I correct in thinking that these strip LED’s can be cut off and used individually? I was thinking if using them to illuminate buildings. Thanks Tony Link to post Share on other sites More sharing options...

RMweb Premium melmerby Posted October 1, 2020 RMweb Premium Share Posted October 1, 2020 (edited) Yes, you cut them where the solder pads are, straight across between the plusses & minuses. 3 leds per unit. If you are doing a lot you can buy them on reels, which I have done. The ones I bought are actually way too bright and need the voltage reducing considerably to dim them. Second Edit If you are talking about using each individual LED on it's own, yes but each needs a separate resistor, in which case why not buy the LEDs individually along with suitable resistors.

Thanks for the info and, to answer the Second Edit, because I already have the LEDs, I have the resistors, and it's a chance to learn a little bit more about how to use components. I enjoy fiddling about with bits and pieces and if I don't have to buy anything extra it's even more satisfying! Tony Link to post Share on other sites More sharing options...

The original resistor is on the back with the rest of the wiring. 1 Link to post Share on other sites More sharing options...
Tony Davis Posted October 1, 2020 Author Share Posted October 1, 2020 Yes, that looks the part. Link to post Share on other sites More sharing options...
DCB Posted October 3, 2020 Share Posted October 3, 2020 These strips are good for imitating modernish image fluorescent lighting whether coach or building but individual LEDs hung from the ceiling look more convincing in old buildings or compartment stock. |It looks like they only have a single resistor so you will need separate resistors for each chunk if you start cutting. 21st century stock really needs white LEDs, 1 Link to post Share on other sites More sharing options...

RMweb Premium ColinK Posted November 1, 2020 RMweb Premium Share Posted November 1, 2020 While all the pictures I’ve seen have the power being applied to the ends of LED strips, could I solder the power leads (3v in my case) to the solder pads in the middle of the strip?

Yes you can, the sets of solder pads are simply sitting on two continuous power rails going the full length of the strip. The 3V I think you will find will be too low, these strips come in two varieties 24V and 12V the latter being the more common. As someone has already stated they will be quite bright and may need additional resistors to reduce the current to acceptable levels and only experimentation will reveal how much.

RMweb Premium ColinK Posted November 2, 2020 RMweb Premium Share Posted November 2, 2020 Thanks, that will keep the wire runs much shorter. Link to post Share on other sites More sharing options...
RMweb Premium ColinK Posted November 2, 2020 RMweb Premium Share Posted November 2, 2020 I’ve put the 3v CR2032 battery in the centre vestibule. Very surprised how bright the lights are. With the room lights on. With the room lights off. 1 Link to post Share on other sites More sharing options...
