How do you warranty a can that you found on the internet?
Are they UL listed?
Just a word of caution:
It’s good that you are looking for ways to be more competitive, that is the name of the game.
However, to some degree you assume responsibility for all material you provide, for any given project. If these cans have a counterfeit UL, or are otherwise defective, you are exposed to any liability that may arise from the use of these cans. To a much lesser extent, if a part breaks within the warranty and you get hooked into replacing it, where do you find it a year later.
Ok best case scenario here, the client loves the cans, they work perfectly and a year later they want more for an addition to the project. Now does that online supplier still have them or is he even still in business?
For fixtures and gear I prefer to deal with a local supply house, to help insulate me from the issues above. If you have any issues with the fixtures, and you bought them from a supply house you then have the assume buying power a supply house has to deal on your behalf with the manufacture of the fixtures. If there is a law suit, the supply house also gets a part of that pie too, and it goes up from there to the manufacturer.
In a nutshell, there is a lot less exposure buying that Halo for $30 than there is for the generic brand off the net for $20, and that is $10 well spent.
My experience has been that some customers will pinch pennies until they hurt themselves and then expect you to fix it out of your own pocket.
