〔SD〕Shashin Denki Kogyo Co., Ltd. RIFA-F 40x40cm Simple Tripod Head Type 1-Light Unit (Includes storage bag and diffuser) This is a RIFA-F 40x40cm 1-light unit only. Lights and light stands are not included, so you will need to purchase them separately. Purchased in 2013, it has only been used a few times and has been stored at home. There is some feeling of use, but the condition is relatively good. I have two of these, so please let me know in the comments if you would like more than one. I am also selling a halogen lamp separately. Accessories: Storage bag, diffuser When in use: Light-emitting surface 40cm x 40cm When stored: Folded umbrella shape, approximately 45cm in length Recommended light stand: Manfrotto 001JB Recommended bulb: Halogen lamp 100V 300W (sold separately) [Product Description (from website)] The diffuser is a square with sides of 40cm. It is the smallest and easiest to handle in the RIFA series, being lightweight and easy to set up even when lighting from directly above. For shooting small items, this 40cm x 40cm RIFA and a paper reflector are usually sufficient for most shoots. However, for shooting large items such as desks and chairs, the 40cm x 40cm RIFA does not have enough light-emitting area, and a larger RIFA is necessary. However, even in that case, this 40cm x 40cm RIFA is never wasted. When shooting large objects, an additional light source is almost always required. At that time, the 40cm x 40cm RIFA will definitely be useful.
