注意事项
闪光灯在全功率的情况下连续引闪 30 次后，需冷却 3 分钟左右。如果连续使
用而不冷却就会产生高温积热。
不可长时间连续使用造型灯，否则可能造成安装在灯头上的柔光箱等易燃附
件燃烧。有易燃附件时建议不要连续使用造型灯超过 10 分钟。如使用超过
10 分钟，请冷却 1 分钟后再继续使用。
使用束光筒时，请勿长时间点亮造型灯或过频闪光 ( 全功率每分钟不多于
6 次 )。积热会导致闪光灯外壳受损或造成灯的损坏。
避免突然的碰撞，防止闪光灯管或造型灯受损。
在使用本设备前请仔细阅读以下警告内容，并妥善保管以便所有本产品使用
者可随时参阅。
请勿私自拆卸产品，如产品出现故障须由本公司或授权的维修人员进行检查
维修。
请保持干燥：请勿用湿手接触产品，亦不可将产品浸入水中或暴露于雨中。
请勿让儿童接触本产品。
摄影灯适用于通风的环境,使用时请保持灯光源部分及散热孔不被堵塞，请勿
在易燃易爆的环境中使用。
摄影灯采用电源插头做为断接装置，应保持随时便于操作。
使用时严禁用手接触灯光发热部件。
安装及连接附件时，请关闭开关断开电源，装卸闪光灯管/造型灯时，请确认
灯管为冷却状态，避免烫伤，还需佩戴绝缘手套。
请勿将闪光灯头正对人眼闪光(特别是婴儿的眼睛)，否则可能会在短时间造成
视力障碍。
在不使用时，请断开电源。

● 接通电源
通过电源线接通交流电源与闪光灯，打开闪光灯上的电源开关(3)，此时充电指示
灯(5)亮红色，表正在充电，不可以引闪；如果指示灯亮绿色，表示已经充满电，
可以引闪。
● 功率调节
闪光功率通过功率调节旋钮(4)来控制，可以从“1/8”至“full”自由调节，满足
客户在不同环境下对光源的要求。（注意：将功率从高至低调节时，需按下试闪
按钮，释放电容能量，再次回电时闪光功率才对应档位功率。）
● 试闪按钮
欲使闪光灯测试闪光而不拍照，请按试闪按钮。摄影师可以通过试闪按钮结合功
率调节旋钮(4)来调节闪光亮度。
● 同步触发
同步线插孔 (2) 规格为Φ3.5mm，此处可插入同步线或者触发器触发插头对闪光灯进
行同步引闪。
● 光控模式
光控模式有3种选择：
（1）没有光控模式：光控模式开关 (8) 拨至居中位置“OFF”，表示光控功能关掉。
（2）1次引闪模式：光控模式开关(8)拨至向下位置“NOR”，表示闪光灯接收到1
次外界闪光可以同步触发闪光。此模式可以做副灯使用，创造多种光影效果。
（3）2次引闪（防预闪）模式：光控模式开关(8)拨至向上位置“PREF”，表示闪
光灯在2秒内接收到2次外界闪光，接收到第2次时可以同步触发闪光。此模式可以
做副灯使用，适用于TTL闪光环境。具有防预闪功能，适用带一次预闪功能的相机
能用光控实现同步拍摄。
● 造型灯使用
造型灯开关(7)控制造型灯的打开和关闭：拨至靠左位置“O”表示造型灯关掉；拨
至靠右位置“-”表示造型灯打开。造型灯的亮度可以通过功率调节旋钮(4)调节，
闪光灯闪光时造型灯自动熄灭。
注：不可长时间点亮造型灯，点亮5分钟后请冷却1分钟后再继续使用。
● 闪光灯管装卸
关闭所有电源，带上绝缘手套，将闪光灯管上的铁丝拧松，用平衡力拿住灯管两
脚间，轻轻往外拉出卸下旧灯管。将旧灯管两脚上的套管取下套到新灯管两脚，
拿住新灯管两脚间，对准灯头上两铜柱，用平衡力往里推进。最后将铁丝拧紧固
定好灯管。

To prevent damage to the product or injury to you or to others, read the
following warnings in their entirety before using this product. Keep these safety
instructions where users can read them for ready reference.
Do not disassemble or modify. Should the product break down, send the
defective back to the authorized service center for inspection and
maintenance.
Keep dry. Do not handle with wet hands, immerse in water, or expose to rain.
Keep out of reach of children.
Please put the device in a ventilation environment and keep the parts of
lighting and heat dissipation holes are unobstructed. Do not use in flammable
environment.
As this product adopts make and break device, please keep it easy to be used.
No touching the heating parts of this product.
Please turn off the power and wear insulated gloves before installing and
connecting accessories. When replacing the tube or modeling lamp, please
make sure that the tube is cool and wear insulated gloves to prevent burns.
Do not flash directly towards naked eyes (especially those of babies),
otherwise it may lead to visual impairment.
Disconnect from the power supply when it will not be used for an extended
period.
Caution
After 30 continuous flashes at full power, the flash should be cooled down for
about 3 minutes. Overheating will occur if it is used continuously without cooling
down.
Do not keep using the modeling lamp for a long time; otherwise flammable
accessories attaching to flash head, e.g. softbox will get burnt. A 10-minute time
is recommended in this case. After 10 minutes, cool it down for 1 minute.
When using a snoot, do not keep the modeling lamp on for a long time or fire
too frequently (not over six times for one minute). Overheating will result in
damages for strobe housing and/or studio light.
Avoid sudden impacts as this can damage the flash tube and/or modeling lamp.

● Power Connection
Connect the flash to an AC power source via power cord and turn the power switch
(3) to ON position. The charging LED indicator (5) will grow red meaning the unit is
charging, no flash at this moment. When the unit is ready to fire, the light will turn
green.
● Flash Output Control
Flash output controller (4) controls the power radio, adjustable stepless power from
1/8 to full. It can satisfy the light requirements in different environment. (Note: When
adjusting the power from full power to a lower setting, press the test button to
release the power in the capacitor, so when recharged, the flash output will be in
the corresponding setting.)
● Test Button
To fire the flash without taking a picture, push the test button. It will also adjust the
brightness when combined with the flash output controller (4) .
● Sync Triggering
A sync cord (2) is provided with your flash unit, and the input is a Φ3.5 mm mini
plug. When working with sync cord triggering method, insert one end of sync cord
or a trigger plug into it; the flash then can be fired synchronously.
● Slave Trigger Model
Three choices available:
（1）No optical control: The optical control and anti-preflash switch (8) is set on the
OFF position, meaning the slave trigger model is shut down.
（2）Once trigger model: The optical control and anti-preflash switch (8) is set on the
NOR position, meaning the flash will be fired synchronously with one external flash. This
model can act as an auxiliary lamp, offering various effects of light and shadow.
● Flash Preparation
Mount the flash unit on an appropriate light
stand and adjust the mounting bracket (11).
Make sure it’s tightened and fixed. The
umbrella input (12) is applicable for any
studio umbrella.

（3）Twice trigger model: The optical control and anti-preflash switch (8) is set on
the PREE position, meaning the flash receives twice trigger in two seconds and will
be fired synchronously. This model can act as an auxiliary lamp, applicable to TTL
flash environment. And with anti-preflash function, it can work for the cameras
equipped with once preflash model.
● Modeling lamp
Modeling lamp switch (7) decides whether the modeling lamp is on or off: the switch
set left (O position), it’s off; the switch set right (I position), it’s on. Brightness can be
adjusted by flash output controller (4). It turns off automatically when the flash fires.
NOTE: Do not keep long time in using the modeling lamp. It’s better to be cooled
down for 1 minute after 5 minutes continuous use.
● Tube Replacement
Turn down the power before replacing the flash tube and wear insulated gloves.
Then, loosen the iron wire on the tube, keep a balanced hold on the two feet of the
flash tube and pull out the old tube gently. Take down the feet casing to put it on the
new one. Hold two feet of the new tube, and target directly towards the two copper
outlets, then push them slightly in. Tighten the iron wire to fix the flash tube.
● Buzz Function
The device is equipped with buzz function. It is turned on when the buzz switch (8)
is set downwards, and then a “BI” sound will be heard when it is fully charged.
Maintenance
● Shut down the device immediately when it works abnormally and find out the reason.
● Avoid sudden impacts and the lamp should be dedusted usually.
● It’s normal for lamp being warm when in use. Avoid continuous flashes when it
● is not necessary.
● Maintenance of all the flashes is up to our authorized maintenance department which
● can provide original accessories.
● One year warranty period will be canceled when any unauthorized maintenance
● is found.
● If the product had failures or is wetted, it can be continuously used only after it is repaired
● by professionals.
● Disconnect the power when doing maintenance work or cleaning.
● New changes made to the specification may not be updated in this manual.
