When you are choosing a speedlite for lighting studio flashes, the first decision is usually power and control versus size and simplicity. The Godox TT600 2.4G Camera Flash Speedlite and the Godox iM30 iFlash Camera Flash sit on opposite sides of that choice. Both are Godox speedlites listed in open-box condition, but they are aimed at different shooting needs. If you are building a kit, the question comes down to whether you will fire lights off-camera or need a quick, compact flash on the camera.
Quick verdict
If your main work is off-camera lighting with multiple flashes, the TT600 is the better match. If you want a speedlite that is easy to carry and simple to use on top of the camera, the iM30 is the more practical pick. The price bars in the table below show the gap in listed prices at a glance.

Where each product wins
The TT600 is the stronger choice when you are setting up off-camera flash work. The iM30 is the stronger choice when you want a smaller, more portable speedlite for everyday on-camera use. Neither is a universal tool for every flash job, but each has a clear lane.
Godox TT600 2.4G Speedlite
The TT600 is built around Godox's 2.4G wireless X-system, so it can be used with compatible triggers and flashes for remote control. It lists a GN60 guide number and a flash duration of 1/300s to 1/20000s, which gives you more output headroom and shorter flash bursts for creative control. If you are building a multi-light studio setup, the TT600's feature set lines up with that workflow. The trade-off is that the unit is listed as open box, so it is not a factory-sealed retail item. You are choosing wireless flexibility and more output, which makes sense if your lighting work is mostly off-camera. For someone assembling a Godox-based trigger system, the TT600 is the more capable partner.
Godox iM30 iFlash Speedlite
The iM30 takes the opposite approach. Its pocket-size body and replaceable battery make it an easy flash to keep in a camera bag for on-camera fill light. It offers seven power levels, and the listing names compatibility with Canon, Nikon, Sony, Fuji, Panasonic, Olympus, and Leica models that have a center hot-shoe contact. That broad compatibility makes it easy to move between camera systems. The listing also includes a 1-year manufacturer warranty, which is a useful addition at this price point. The trade-off is the guide number, listed at 15, which is much lower than the TT600's GN60. If you stay within its power range, the iM30 gives you a flexible, low-complexity option for basic flash work.
Final choice by use case
For wireless studio flashes, choose the Godox TT600 at USD 59.00. For a compact on-camera flash with broad compatibility, choose the Godox iM30 at USD 27.66. If you invest in a wireless studio lighting kit, the TT600's system integration matters more. If you simply want a small speedlite that travels well, the iM30 is enough.
