Korean lighting manufacturer Rimelite have announced their first cordless TTL strobe in the compact 400Ws i4 TTL.
The i4 TTL are Lithium-ion powered IGBT strobes, with both Canon and Nikon compatible Rimelite 2.4GHz TTL and HSS enabled radio receiver built inside.
The i4 TTL are not Rimelite’s first cordless strobes though, their range of remote manual i-flash strobes (commonly known as the Dynalite Baja B4 & B6 in the USA) have been available for a few years already.
The i4 TTL are a new design though, and as well as adding TTL, and pulsing HSS modes, the i4 TTL are more compact than the original i4 (now providing a recessed flash tube), and shaving a considerable 600 grams off the previous weight.
And that is likely helped by the i4 TTL’s smaller capacity 11.1V 4400mAh battery, which still provide a very reasonable 330 full power pops.
The i4 TTL’s recycle time is also a respectable 2.4 seconds at full power.
The i4 TTL provide a full color TFT LCD interface, and offer TTL, Manual, and Multi flash modes.
Manual power range is from 1/128 to full power, in 1/10th stop increments.
Both Canon and Nikon compatible Rimelite 2.4GHz radio receiver modes are built inside.
Providing 4 flash groups A/B/C/D, and 99 channels.
The i4 TTL share their TS-4 transmitter unit with fellow Korean company SMDV’s Flashwave-5 TX transmitter, developed alongside the compact SMDV Briht-360 TTL strobe.
(Its not confirmed if the Rimelite and SMDV transmitters are fully compatible, though that is likely).
The TS-4 transmitters are available in separate Canon and Nikon versions, and provide 4 Groups, 99 Channels, and up to 100M range.

For location use the i4 TTL now feature a more compact recessed flash tube arrangement, with a robust protective glass cover.
And once again a standard S-Type accessory mount is built-in.
A 10 watt LED modeling also provides a unique AF assist mode, where the light will come on with a half press of the camera’s shutter release button while focusing.
Power supply is via an interchangeable 11.1V 4400mAh Lithium-ion battery, providing up to 330 shots at full power, and up to 1800 shots at minimum power.
With a full recharge time of approximately 3 hours.
There is no mention of any AC power option available for the i4 TTL strobes.
Though strangely Rimelite do have AC adapters listed for their coming Manual version of the new i4 strobe. So its not clear yet if those may actually be compatible with the i4 TTL strobe as well or not.

PRICE AND AVAILABILITY
Price and availability of the Rimelite i4 TTL have not been specified just yet.
(Though if previous i4 / Baja B4 prices are any indication the i4 TTL should be quite reasonable).
