First of all, let's clarify the function of the modeling light again: 1. Modeling, composition, focusing, and viewing details; 2. Simulating the light ratio; 3. Reminders to call back. For photographers, these functions are very meaningful, some can improve shooting efficiency, and some can improve shooting quality. Therefore, modeling lights are essential for flash and must be paid attention to.

With the above consensus, let's discuss again, which kind of modeling light flash should be preferred when buying flash. At present, there are two main styles of flashlights on the market: in-line halogen bulbs and LED lamp beads.
 The service life of LED lamp beads is very long, with a nominal 100,000 hours, and the worst is also nominally 50,000 hours. What is this concept? That is to say, if you turn on the full light and use it 24 hours a day, it can be used for 11 years. Of course, the claims are all in ideal conditions, and of course there will be no photographers who use full light 24 hours a day. In short, as long as there is no problem with the cooling system of the flash, the LED modeling light can be used all the time. It's a one-time purchase, no cost for a lifetime.
