The PB-2600LED is a combination kit of the PB-2600E Hard Case and the PR-C2LED soft case.  This combination gives you the option of carrying the soft case, or comfortably nesting the soft case into the hard shell, making it a shipping case.
The PR-C2LED is a padded protective case for carrying LED lights. The case is constructed using abrasion-resistant 1000-denier Cordura nylon material. The material is also treated with layer of water-resistant protection. There is half-inch foam padding throughout to protect the LED light during transport. The case has a single, durable YKK zipper that unzips to allow the case to open flat for easy access to the light. Interior Velcro tie-down straps help secure the light inside the case for extra protection. There are strong solid-steel rings for clipping to the comfortable non-slip shoulder strap (included). The PR-C2LED can also be carried using the suede-covered nylon handles. 
The PB-2600E Hard Case is a watertight, high-performance hard resin case for video, audio, and photographic equipment transportation and protection. It is watertight and airtight with a pressure relief valve, easy to operate latches, and a comfortable hand grip. The patented resin material is lighter than many comparable brands, which helps reduce fatigue and shipping costs.The PB-2600E is constructed with a high-performance hard-resin material reinforced at the corners. The PB-2600E is ideal for audio, and photographic equipment.
This case has an empty interior. See PB-2600F model for cubed foam interior
