Any of you in the Stockport direction may have just witnessed the sign of light dawning…
I wondered what SpeshPaul was talking about when he said he’d posted my drawing on the lumicycle thread – I’d not realised there were two and have only just stumbled across this one!
Where to start…..
Basically, it seems that I’m not going to get any heatsinks done through work. Internal politics is making it too messy. No-one has got back to me regarding the posted drawing so unless emails have gone astray (I seem to be having similar issues to Troutie as I’m on VM as well) then it isn’t looking good for these from my end.
However, those that Troutie have done seem great to me. The one thing I’d not realised is that I’d designed the lumicycle driver based on the LED board having two pin connections in the middle. Looks like the newer XPE/G boards don’t have that – the driver was in effect intended to hang off the LED board. If you look at

you may get the idea. I’ve got these drivers, had them ages but not been able to sort heatsinks. If they can be fitted in Troutie’s heatsinks then I can supply no problem, if the standard drivers fit then that is fine also. I designed the lumi one to sit flat across the can to leave more space for the switch etc.
The new boards have been up and around for a while – check my eBay shop. I’ve combined the standard and dim-mode ones but they are now slightly larger to aid cooling. I have also now added 500mA and 830mA to the standard range as an experiment – not sold any 500s yet but have done a few 830s. I’ve posted before that I think 1A is too much for the halogen can but the 830 should be a good compromise. Should note that 670 and lower is a different PCB and is about the same size as the old driver. At lower currents heat isn’t an issue and I’ve been able to cost-reduce some parts to get the price down. Hope they don’t prove too popular though as I got fewer of that size than of the 1A size as in the past 1A had been by far the best seller.
I’ve also go a bag of centre-off switches that use the same boot as the standard lumicycle switch so you can change the switch over and get off / on / dim power modes.
I’m also looking at doing something for the HID can – I’ve got a driver board prototype made up but am having the same hassle getting heatsinks. (Sorry, Scott if you are reading this! I’ve not forgotten…)
Troutie – would it be worth me sending you a lumicycle-type driver to see if they can be used with your heatsink? Also, if I get a drawing made up of the HID heatsink do you think there is any chance you could get some of those made up as well? (BTW, did email you a few weeks back about the small batch of drivers you’d enquired about, don’t know if you didn’t get the email or you just don’t need them any more)
