I bought this battery, order the video light "Nanguang Bi-Color LED Light Soft LuxPad 22" to operate. The purchase of a battery was necessary because it was not possible to run this video light with full light. If you are interested take a look at my review of this video light. The performance of this battery has even exceeded my expectations. The battery allows the video light at full power light more than 5 hours. The battery is for the five hours but not empty. If you set the light slightly weaker, then the video light is available still long. On this occasion, thanks again to Mr. Tobias chamber tent, by the company. Bundle Star, for the rapid setting of the charger for this battery on ebay. I would buy this battery anytime.
