The Profoto twin head has two flash tubes in one head. This can be used for maximum Power (4800WS) when using two Pro 10 at full power, or to achieve fast recharge and short flashduration either by using the head on one pack, or split it at low power setting to two packs. Get in touch with our crew to find the best solution for you. Classic is the use with a Mangum reflector on a highstand far away from the set to get a "Sunlight effect" with hard shadows.
