I noticed that the new Kingsford® Match Light® charcoal Charcoal briquets do not burn as long.

New Kingsford® Match Light® charcoal briquets burn as hot and as long as our old charcoal. Kingsford® Match Light® charcoal briquets are now ready to cook in 10 minutes. This is about 25 percent faster than other charcoal available today. As a result, you will need to put the food on the grill earlier to take advantage of the extended cooking time that Kingsford® Match Light® charcoal provides.
