sdw7300 Posted December 3, 2014 Share Posted December 3, 2014 The lights are looking really good. Is it just one christmas light behind each pit light? (Could I trouble you for a photo?) As ever, fantastic modelling. Cheers 1 Link to post Share on other sites More sharing options...
Grimleygrid Posted December 5, 2014 Author Share Posted December 5, 2014 Hi Sam, thanks. I am pleased to have seen 30 odd lights in one pit lit up, quite a sight, albeit a little too bright! You are correct, one LED behind each light. I have taken some photos which I will post later. If it helps, the lights were purchased from The Range by Grimley Senior. I planned to post a photo of the box for those interested but unfortunately Mrs Grimley threw it out, she thought that it was rubbish! Never mind….. Here is a link to The Range website, whilst the version we have is yellow ribbon lights and not green this gives you an idea of what we are using: http://www.therange.co.uk/50-bulb-green-ribbon-light//the-range/fcp-product/102707 Will post some photos shortly. 1 Link to post Share on other sites More sharing options...
Grimleygrid Posted December 5, 2014 Author Share Posted December 5, 2014 Hi Sam, Here are a few photos of the LEDs: The Christmas lights come in a 5m length with 50 LEDs covered in a yellow ribbon. Here you can see we have removed the majority of the yellow ribbon: image by AP474, on Flickr A close up of the LED: image by AP474, on Flickr The LEDs working: image by AP474, on Flickr LEDs taped to the rear of the inspection pit, this example has the LED facing inwards: image by AP474, on Flickr This LED is facing outwards, this does make a difference to the amount of light passing through the hole: image by AP474, on Flickr Hope that helps. 4 Link to post Share on other sites More sharing options...
Grimleygrid Posted December 5, 2014 Author Share Posted December 5, 2014 Grimley Senior has been making a current regulator, using an LM317 (whatever one of those is!) to help dim the LEDs. Hopefully over the next couple of days this will be ready and I will be then able to experiment and get the lights at a more acceptable brightness. Then we can start installing them properly. 3 Link to post Share on other sites More sharing options...
sdw7300 Posted December 5, 2014 Share Posted December 5, 2014 (edited) Getting all those tiny LED's pre-wired certainly makes life easier! Looking really good. Cheers Edited December 5, 2014 by sdw7300 Link to post Share on other sites More sharing options...
RMweb Gold mudmagnet Posted December 5, 2014 RMweb Gold Share Posted December 5, 2014 Those LEDS look just the ticket, apart from the brightness! For that price, could be a very useful item to have. Trouble is, we don't have a Range down this way, but a visit to similar places may be on the cards! Link to post Share on other sites More sharing options...
Grimleygrid Posted December 9, 2014 Author Share Posted December 9, 2014 Hi Sam, it certainly does. Very good value if you ask me! Hi MM, the LEDs so look good, as you say, albeit slightly too bright! Great value though, hopefully once dimmed a little they should look okay. Grimley Senior went to another Range store but unfortunately didn't have any! Typical, however he did come away with these, for some unknown reason I cannot paste the link! If you go on The Range website and type in 81387, 150 warm white LEDs. I think these might be useful too although we have not lit them up yet. You could always get them delivered! I also noticed the other day that B&Q have quite a selection of LED Christmas lights, might be worth a visit. 1 Link to post Share on other sites More sharing options...
Grimleygrid Posted December 10, 2014 Author Share Posted December 10, 2014 Dimmer ready for testing: image by AP474, on Flickr Hopefully later! 3 Link to post Share on other sites More sharing options...
Grimleygrid Posted December 11, 2014 Author Share Posted December 11, 2014 This afternoon the dimmer was tested and whilst the LEDs were definitely not as bright, it didn't quite have the desired effect. Version 2 is currently being worked on! I will post a few photos later to show the difference. Link to post Share on other sites More sharing options...

class"66" Posted December 11, 2014 Share Posted December 11, 2014 Very nice looking class 58,must realy buy one of these soon.. cheers neil. Link to post Share on other sites More sharing options...
Grimleygrid Posted December 12, 2014 Author Share Posted December 12, 2014 Hi Neil, I do like 58s. In my opinion the Heljan 58 captures the look of the class very well and they look great in Original Railfreight too!I would definitely recommend getting one, they are lovely models. I seem to be going through a 58 phase, keep browsing Flickr for photos of them in Original Railfreight. Better control this otherwise my wallet will come out and before you know it a couple more will be on their way…. Link to post Share on other sites More sharing options...
d winpenny Posted December 12, 2014 Share Posted December 12, 2014 The lights look okay to me a step in the right direction at least will await the revised versions,. The Heljan 58s are lovely models I had one for a while in mainline grey livery David Link to post Share on other sites More sharing options...
Grimleygrid Posted December 12, 2014 Author Share Posted December 12, 2014 Hi David, as you say in improvement on before but not quite what we were after. However, I have just been informed by the research and development department that version 2 has been made and initial tests have proved successful. Now for the real test on the inspection pit LEDs. Hopefully tomorrow the new dimmer will be wired up to allow proper testing. I have it on good authority that version 2 does actually dim the LEDs, looking forward to seeing it coupled up! I only have one Coal sector liveried 58, over time I will add a few more to the fleet. A model based on Toton wouldn't be right without lots of 58s on shed now would it?!!! I agree with you they are very nice models. 1 Link to post Share on other sites More sharing options...

Grimleygrid Posted December 14, 2014 Author Share Posted December 14, 2014 Thanks Peter, one of my favourite class 47s. I was very tempted a few years ago by the Limited Editions from Rails of Sheffield, 461 and 541, but in the end thought it was a bit over the top for Boxenby. But, after seeing that photo I think that if may have to get 461! Grimley Senior has just paid a visit to test the latest version of the dimmer and it works! Very well. I have just seen the inspection pit lights having their brightness controlled, very impressive. We can now get them to the desired brightness, superb. Very happy! Now to get boards made up and then get the LEDs installed. I will post some photos later. 2 Link to post Share on other sites More sharing options...
Grimleygrid Posted December 14, 2014 Author Share Posted December 14, 2014 Hi Peter, I have just carried out a search on the internet for photos of 47461 to see if it actually made it on shed at Toton. Guess what, it certainly did: http://www.class47.co.uk/c47_zoom_v3x.php?img=1158051126211&z1=20&z2=-20 I am definitely going to get a Bachmann 47461! 2 Link to post Share on other sites More sharing options...
Grimleygrid Posted December 14, 2014 Author Share Posted December 14, 2014 A few photos, first of all the prototype board: image by AP474, on Flickr This uses Pulse Width Modulation to dim the LEDs whilst maintaining the colourimetry. Here you can see the pulses on the oscilloscope: image by AP474, on Flickr A couple of photos showing before and after, first off one of the LEDs on normal brightness: image by AP474, on Flickr And dimmed down: image by AP474, on Flickr I will post a few more photos later. 5 Link to post Share on other sites More sharing options...

nathan9117 Posted December 15, 2014 Share Posted December 15, 2014 The pit lighting windows are fantastic and the led lights look pretty good too. I remember going down a few pits and they are pretty dim and dark in most cases so the led lights look good from what I can see. I would never have the patience to make the little light windows for the pits . Link to post Share on other sites More sharing options...
class60lover Posted December 15, 2014 Share Posted December 15, 2014 Grimley is no ordinary modeler. If it can be done it will be which makes these thread so much fun and inspiring. Looking good Grimley. Good to see 014 on shed. Link to post Share on other sites More sharing options...
