5w PanFlex Light Card Kit, 3100k, by ProFound (PSK-005SGT)
This is the smallest of the ProFound light sheet kits, the tiny 5w PanFlex, tungsten balanced light card (3100K). It weighs .67oz so saying it adds weight isn't worth the breath. The PSI-005SGT makes for wonderful on-board light, and the dimming system runs off of 5v USB so it can draw power from nearly any mobile device. For cars, eye lights, tight spaces where you need a bit more light without sacrificing a high CRI rated source, this little light can produce wonders. It includes the light head and 5w dimmer.
The smaller sibling of the ProFlex lights, the PanFlex series offers a robust approach to battery operated on-board lighting systems. Different from the ProFlex, the PanFlex light card light sheet is coated in a thin rubber envelope which makes them bendable down the center axis of the light card. PanFlex lights are simple to put just about anywhere and are controlled from their tiny dimmers which draw USB power. The credit card size 5w LED light sheet can draw power from just about any on-board setup, including phones.
