Negative Supply - 4x5 Light Source Pro

The Negative Supply 4x5 Light Source Pro is the next in our second generation of light sources and directly replaces our outgoing 5x7 Light Source Pro.

Designed with 35mm, 120 and 4x5 film in mind, the 4x5 Light Source Pro is created for those who demand a solid, reliable, and bright light source with a high degree of color accuracy without compromise. This light delivers.

Previously, if you were using our 5x7 Light Source Pro in combination with our Pro Mount MK2 you’d find that the Pro Mount MK2 rested directly on the corners of the light source. On our new 4x5 Light Source Pro, the Pro Mount MK2 will rest over the light and not come in contact. This requires higher feet for your Pro Mount MK2.
