• Floodlight

Achieves high-power illumination equivalent to a 400W mercury lamp! With an IP65 waterproof rating, it can be used in salt-damaged areas both indoors and outdoors!

Massively arranged Philips LED chips achieve high-power illumination. With excellent corrosion resistance, they adapt to external environments, making them recommended for lighting in high-ceiling factories, gymnasiums, and sports facilities. They have excellent heat dissipation, and automatically turn off when the maximum temperature of the power supply reaches 95°C. (※ The product has a built-in temperature protection circuit in the power supply.) 【Features】 ■ IP65 waterproof and dustproof, safe to use even in bad weather. (※ Using in heavy rain from typhoons may risk internal water ingress.) ■ Standard specification for 6kV lightning surge, meeting the voltage standards set by the IEC (International Electrotechnical Commission). ■ Confidence with a 5-year warranty, and PSE certification obtained.

High-spec ballast-free light bulb with no noise and flicker-free.

Flicker refers to the "flickering" of a light source that is flashing at an invisible speed. Displays and LEDs may appear to be continuously lit, but in reality, they are flickering at a high frequency that is not visible to the human eye. Even at such an imperceptible flicker speed, cameras capturing a moment or recording video can capture this flicker, resulting in dark photos or flickering images. Additionally, since they do not continuously flow current, power consumption is reduced, leading to lower electricity costs and longer LED lifespan. 【Features】 ■ Waterproof and dustproof with IP65 rating ■ Flame retardant with a slow burning speed, and scorch marks can be easily wiped off with a dry cloth ■ The LED chip is made by "Epistar," a major manufacturer that has a cross-licensing agreement with the Japanese manufacturer Toyoda Gosei.

• Bulb Type

Since it is flicker-free, you won't be troubled by noise and can use it in any location.

The ballast-free type is a flicker-free LED. It can be used in various locations such as ships, heavy machinery, studios, and museums. It is our most popular product, having surpassed a total sales record of 13,000 units. *Please note that this product has polarity. 【Features】 ■ Waterproof standard IP65 Can be used indoors and outdoors due to waterproof and dustproof design ■ Flame retardant ■ Major manufacturer The LED chip part uses "Epistar" which has a cross-licensing agreement with the Japanese manufacturer Toyota Gosei ■ Energy-saving measures The power consumption of LEDs is about 1/8 compared to incandescent bulbs *This bulb is compatible with DC (12/24V). Please note that it cannot be used with non-specified power sources (such as household AC (100V)).
