[QUOTE="Vipersan, post: 960659, member: 325666"] Indeed there is ..and why no one has the gumption to make a thing backwards compatible with an existing system... Money £££££££$$$$$$$$$$$$ Its not that they can't ... It's that they want to make you think going green is lifestyle choice ...and you are conned into parting with even more dosh without questioning ...cos you have that feel good factor that comes with nausiating self important belief that you are doing good and sod the cost.. If each lamp included on that small round pcb ..1x12v 1 amp suface mount regulator after the bridge rectifier .. Cost approx 2p each in bulk ...plus 1x surface mount tantalum electroytic ...another 2p .. then the lamps would indeed be backwards compatible with ac transformers and existing systems ... The regulator making sure 12v is never exceeded ..and the caps dealing with the ripple.. But that would be too easy would it not ...and they couldn't offer you new lighting systems costing a small fortune to install .. sorry I'm grouchy ...but I see this kind of crap every day in the TV tade.. Move the goalposts .. Re-invent the wheel .. Charge more money.. It's called churn...and it cause my stomach to do just that.. cest la vie. [/QUOTE]
