led gu10s in shop

[whats an rb4]

been out of sparking for a while hence the question , we are opening a shop and have some fittings but no lamps yet! so questions are , can these led lamps be wired in series loop in and out on ceiling tiles ,and do i need a resistor somewhere what are pros and cons 230 vs 12 cost wise , ease of installation a priority, was going for cool white in shop area and warm white in tearoom , as you can probably tell i need a push the right direction , any thoughts or ideas for making the job easy bearing in mind i have to pay the elecricity bill aswell would be greatly appreciated

Also just a query how big is this place 80 fittings sounds excessive, do remember 4w only gives equiv' to 35w halogen although the cool white can improve on that slightly, if you want to match a 50watt hal' output then 7w would be a minimum but id get sample lamps before bulk buying so you dont end up with the wrong rating. If its such a large area you might be best getting a lighting design drafted up, it may save a lot of fittings and may even direct you in other lighting schemes, some larger wholesalers will have a design team who will help you out (free if you use their products)
