In the 20th century, early in the 1990s, with the great helping and supporting from China photography association image guild and related scientific research units, Guangbao photography equipment co., ltd has designed and produced "Guangbao" branded professional flash system, leading the tide of China professional studio flash lighting. Beside that, Guangbao professional studio flash lighting are tested by China photographic equipment inspect center, all the technical date are reached or higher than the country standard.

With many years hammer-harden and improving, Guangbao studio flash has became a product with consummate technic & complete system. At present, our main products are EH-K Classical Series, LB Leopard Series, HS Dual-Use Series, YX Economy Series, CR Digital-thinking Series and YZX Generator Series professional flash and their accessories.
Main characteristics:

1. Metal cases made from aluminums, with high level surface processing, to make light body solidity, aesthetic & durable.

2. Exclusive design standard permanent current charging method, fast and reliable recycling, but with low shock current. So especially suit for multi flashes in normal electric condition for safety use.
(For example, EH-300 only use 2A fuse, EH-600K only use 3A fuse, LB-600 only use 6A fuse)

3. Constant output: Exactitude electrical system, even if the voltage of power suddenly up to 220V or down to 150V, GuangBao Flash Units are still completely steady, Output error is only ±1%. This is one of the efforts of GuangBao high technology.

4. Multi sections adjusting: Any flash unit of Guangbao has the ability to achieve the multi sections light adjusting. This is the Guangbao microelectronics technology’s successful application, it’s quite different from the output change that achieve by changing combination of capacitance.

5. Exactitude control modeling lamp, improve the management of modeling lamp to a new level; EH Classical Series & LB Leopard Series all use professional halogen lamp, with optional multi-method (for example auto scale, 100%, 25% or auto switch on/off).

6. Invariableness color temperature: Guangbao flash unit adopt full cycle flash advanced international technology. Therefore, it can keep invariableness and correct color temperature at any output level. The color temperature of Guangbao flash units are adjusted to 5100-5600K, not necessary to adjust and get perfect color if you use sunlight type film; the color temperature of modeling lamp is 3000-3200K, could be directly shoot with lamplight type film.

7. Fast recycle time: LB Leopard Series Flash only required 1 second recycle time to full power, with super fast recycling, the photographers can catch every shoot and freeze every excellent moment with their pleasure.

8. Fast release: very short flash duration, to guarantee every image is in focus and sharpness; even for the movement photography (for example, fashion or children’s photography) or photographers hold the camera in his hand, Guangbao flash (especially EH-K Series, LB Series, CR Series) will have excellent representation.

9. Main parts and components are built by famous high quality brand, for example the flash tubes are provided by PERKINELMER company (formerly Germany HEIMANN company), the capacitances are provided by Japan Rubycon company, to guarantee the quality of inside parts.

10. Adopted exclusive design: use static state high pressure method to test and inspect the flash, to promise the stability & reliability of Guangbao flash – this is point which the traditional dynamic normal pressure test method can not achieved.

11. Advanced triggering method: beside by using wire cord (low voltage) to triggering, build in infrared can also control the flash; recently we pushed Radio Trigger to the market, it’s a revolution of the triggering method.

12. Guangbao flash attaches the importance to practicability, reliability, convenience & durability in design. She got excellent performance and many applied functions, but without flowery attract.

GuangBao - Still working out for new products research and design, continue providing the customers more convenient, practical & reliable professional flash system!
