What BHP are light blues good for?

Just about to put a set I have on ebay and want to get the advert correct. They are good for 400 or more?

This is not a for sale post so you will have to bid for them on ebay!!! Will edit with the auction link once I get an answer!!!!

Cheers,

 

380-400 MAX

 

Thanks!
