Which brand of flashlights is the best and brightest?

I own a lighting store. Generally, there are three types of flashlights in the store: Tiger Head, GP Speedmaster and Yanni.

The best-selling one is Yanni, which is one of the best and brightest flashlight brands in China. Yanni's LED headlights have high brightness, good heat dissipation effect, and the aluminum alloy heat dissipation cup is of high quality.

The second is Tiger Head. Tiger Head is a famous Chinese trademark that started in 1921. It is the brand of Guangzhou Huhui Lighting Technology Co., Ltd., China Lighting Engineering Technology Research and Development Center.

The appearance of Speedmaster is eye-catching. Speedmaster is the world's leading supplier of consumer batteries and is well-known around the world. As an alkaline battery brand, GP Speedmaster is loved by consumers for its excellent quality and eye-catching appearance.
