● Sunstar's ZERO series of small location generators, the mid-range model 004 and mini-2400 head with 2-light case, are available at a discounted price due to a defect. The reason for the defect is that the charge lamp cover is missing and the switch is not functioning. Testing shows it can be used without problems with the flash switch. I have confirmed that the set's heads can be connected and that all functions, including flash, dimming, modeling light, slave, and sound, work. Accessories include a dedicated power cord, two easy-to-use 4M head cables, a sync cord, and the original location bag to hold everything. ● There are some white areas on the heads, but according to the manufacturer, this is a phenomenon that occurs when using continuous shooting and is not directly related to the lifespan. Overall clouding, or the black part at the base of the flash tube, which is called a getter, disappearing, indicates the end of its lifespan is near, so I think you can still use it actively. ● This is a 1200W, 3-light output generator with automatic switching for equal output (using only AB) or asymmetric output of AB 800 / C 400. I use it for model photography, and at 1/4 output, it takes about 1 second, so there isn't much stress (subjective). At full power, it takes about 3 seconds, which is the same as a typical small generator. ● Since it hasn't been used for a while, I think aging is necessary before serious use. I recommend gradually increasing the power. I think it's still equipment that can be used actively. ● We sell with a performance guarantee, so we will address major defects such as failure to flash upon arrival.
