The Profoto B1 500 AirTTL is a battery-powered monolight strobe designed for on-location shoots. We also offer the B1X 500, an enhanced version of this light, at the same price. Key features include:
500Ws, 9-stop power range
Lithium-ion battery powered
Up to 220 full-power flashes
Compatible with Air Remote TTL Transceiver
Removable Battery. The included lithium-ion battery provides about 325 full-power flashes per charge, or up to thousands of flashes when you lower the power output. The battery attaches to the side strobe housing itself, making it easy to move around with. The strobe cannot be AC powered, so once the battery is depleted you’ll need to recharge or swap batteries before you can continue shooting.
Flash Output. The B1 500 AirTTL offers a 500Ws maximum output, with 9 stops of adjustment in 1/10 or 1-stop increments. Maximum recycle time at full power is 1.9 seconds, and a Quick Burst Mode enables 20 fps at a reduced power level. Two additional modes (Normal and Freeze) allow you to prioritize faster flash duration or minimal color shift depending on your needs.
LED Modeling Light. The 20 W LED provides the equivalent of 70 W tungsten light.
Supports TTL Air Remote. The B1 500 AirTTL offers full TTL support when matched with one of the Profoto Air Remote TTL Transceivers for Canon, Nikon, Olympus/Panasonic, or Sony. Please note that these are separate rental items.
Triggering Options. This strobe has a built-in Profoto Air radio receiver, allowing it to be triggered by any of the TTL remotes above. You can also use the Profoto Air Remote Transceiver if you’re comfortable with manual power adjustment. You’ll get 300 feet of range when triggering in TTL mode, and 1,000 feet with normal radio triggering. Additionally, there’s a 1/8-inch mini-sync input if you prefer using a sync cord, as well as built-in optical secondary flash.
Profoto Build. The B1 500 AirTTL borrows much of its design from the company’s D1 monolights. It uses the same durable polymer housing, features a built-in fan, and has an integrated 77-degree reflector. The controls and display on the rear panel are intuitive and user-friendly, and a mini-USB port behind the battery lets you update the firmware when new features are added. The B1 strobe is compatible with the same modifiers as the D1 monolights, allowing simple integration for existing Profoto users.
