In conjuction with Tom Vadnais's flash workshop at BIOCOMM 2025 Godox have offered a discount for conference participants at B&H , valid through to May 15. Use code GDX525 for 10% off a list of items.

To understand the model number columns in the Godox e-mail below, here are the B&H links for the flashes, triggers, umbrellas, and diffusers. (Note: the flash and trigger links are all to the Nikon versions, but you can access any other camera system from that page. Of course, umbrellas and diffusers aren’t specific for any camera brand.)

Flashes:

Godox TT685II (N, C, F, O, S) $129 less 10%: https://www.bhphotovideo.com/c/product/1669849-REG/godox_tt685iin_tt685n_ii_flash_for.html. These rectangular head flashes are the ones I use and brought for the workshop. These flashes have the same specs as the top-of-the-line flashes from Nikon, Canon, and Sony. They take AA batteries. I highly recommend Powerex Pro rechargeables: https://www.bhphotovideo.com/c/product/1531749-REG/powerex_mh_c980_turbo_charger_analyzer_and.html.

Godox VING V860III (N, C, S) $170 less 10%: https://www.bhphotovideo.com/c/product/1341867-REG/godox_v860ii_f_nikon_kit_v860ii_for_nikon_kit.html. These are the same as the TT685II flashes, but they use a proprietary Li-ion battery instead of AA’s.

Godox V1 (N, C, F, O, S, Pentax) $259 less 10%: https://www.bhphotovideo.com/c/product/1465917-REG/godox_v1_n_v1_flash_for_nikon.html/specs. These are round head flashes with proprietary rechargeable batteries. These flashes are more powerful than the TT685II flashes.

Flash Triggers:

Godox X3 (N, C, F, O, S, Leica) $89 less 10%: https://www.bhphotovideo.com/c/product/1803869-REG/godox_x_nano_n_touch_screen_transmitter_for.html. Tiny size with touchscreen for remotely controlling single or multiple off-camera flashes. Internal rechargeable battery. I’ll be using one of mine during the workshop. Takes the place of a master flash mounted on the hot shoe if you don’t need flash from the camera position.

Godox XPro (N, C, F, O, S, Pentax) $69 less 10%: https://www.bhphotovideo.com/c/product/1369138-REG/godox_xpron_wireless_flash_trigger_transmitter.html. Larger than the X3, but still a lot smaller than a flash itself. Uses AA batteries and has intuitive controls similar to the TT685II flash. I’ll have one of these at the workshop, too.

Umbrellas and Diffusers:

Godox Parabolic Umbrellas in 34”, 41.3”, 51”, and 65” sizes (white, silver, and transparent) $19 through $59 less 10%:https://www.bhphotovideo.com/c/search?Ntt=godox%20parabolic%20umbrella&N=0&InitialSearch=yes&sts=ps. Note: The discount code is not valid for the parabolic reflector kits.

Godox Diffusers for Parabolic Umbrellas (in equivalent sizes) $9 through $15 less 10%: https://www.bhphotovideo.com/c/search?q=godox%20parabolic%20umbrella&filters=fct_category%3Aumbrella_diffusers_31190. These turn your umbrella into a softbox. Note: The discount code is not valid for the parabolic reflectors.

Important Note: The discount code is in effect from May 1 through May 15, 2025. This code is only valid at B&H Photo, but they ship worldwide (https://www.bhphotovideo.com/find/HelpCenter/International.jsp#whereWeShip). If shipping internationally, I would check your country’s shipping rules, particularly for products with Li-ion batteries (VING 860II, V1, and X3).
