Bro, u study the pattern of the LED, yesterday at SLT B1, I saw something like this in one of the shop but only have in longest is 1m length in aluminum rigid casing, so I didn't buy as I need longer than 1m, guy tell me I have to go and get my own aluminum from some hardware shop in Jalan Besar and he will use flexible LED to mount. But I saw ready made ones like what u posted, u go check it out. If u enter from SLT main entrance, walk down stairs to B1, shop is on the right hand side near the end, he display quite a few LED on a display right..., u go recce...but I dun think they know specification, u need to study the LED pattern, maybe get a printout and see if it's similar. Good luck
