Being the light quality but felt pretty good, the Aputure AL-528w LED video light which features steady light and strong, manual brightness control, and uses PWM technology to decrease power dissipation. By using the Amaran 528 to get the same professional lighting seen on TV and Hollywood. There is no doubt that the light is expandable for maximum brighness, small for easy portability, and has efficient dual power supply system. All features stands for high quality but low price. Aputure al-528w led video light uses a digital brightness display to show output by percentage. Rotate the brightness wheel to adjust output from 10% to 99%. Use the power adapter to power the unit through a wall outlet, or you can use the batteries (Sony F/FM/QM Series) when shooting outside and a Low power warning with red blinking lights when the batteries are low. The included AC Adapter could be used as battery charger. Main Features Functions

The frequencies Baofeng bf 888s that come on the radio from the factory are mostly good in the USA. Channel 6 and 7 are legitimate GMRS, but you need a license to use them. You must reprogram most of this radio to operate on legal frequencies. The only ones that are legal are GMRS and HAM (unless you have a business license that falls within the range of these radios).At full power, you have to have a license of some sort. Either a GMRS, HAM, or some commercial license for other frequencies. The radio can be programmed for any frequency and repeater offset between 400 mhz and 470 mhz. You need to be very careful because some of these frequencies are for emergency beacons, Satellite operations, and government. Battery life is excellent. Took a trip of about 200 miles chatting from car to car and were still working strong at the end.
