Where shoudl i source my LED dowmnlights

I am currently working on a building project and was wondering which supplier i should use, i specifically need LED down lights around 12-14 w ( about 600) , my electrician friends have told me to buy from a company named CLSA . They said when they use the last year for an apartment complex , they were good quality and decent price. Has anyone done business with them are they good. This is there website clsaled.com.au . Im kinda leaning towards them as they are based in Melbourne and was a pretty cheap quote for 600. on average $26.5 for 600 @ 12W. Anyone know any better prices?? Please reply ASAP as i need to get the order in before June 10
