Nikki NLH200U-HL Series Hanging LED floodlight
Manufacturer: Nikki Co., Ltd.
Model: NLH200U-HL Series
Features
The body is made of aluminum and the front is made of resin, making it a lightweight, long-lasting economy type that maintains high heat dissipation properties.
With brightness equivalent to an 800W mercury lamp, it is ideal for ceiling lighting in general factories and warehouses at a height of around 10m.
The LED body and power supply are integrated, and there are two types: a hanging type (HL) that can be hung with a wire, and a bolt-fixed type (HL2), which can be selected according to the application.
Compared to mercury lamps, they are more energy efficient and have a longer lifespan, allowing for significant savings in electricity and replacement costs.
*When installing, be sure to attach the fall prevention wire.
Application Examples
Factories , refrigerated warehouses , indoor parking lots , etc.

Thorough lightning protection
The current-isolating design quickly diverts induced lightning surges, protecting products from lightning strikes. (It can discharge up to 10kA with a surge waveform of 8/20μs.)
When lightning strikes or lightning discharges occur, induced lightning surges occur in power lines, destroying many electronic devices. This product has a built-in lightning surge protection element.
±6kV between lines, ±15kV to earth

SPD (Lightning Protection Device)
This LED floodlight is protected by limiting sudden, violent current fluctuations (surges) caused by lightning and other events.
A typical lightning strike generates a surge of several tens of kV or more, but this LED floodlight has an SPD installed between the power supply IC and ground, so that even if a lightning surge enters the building during a lightning surge, it is discharged from the SPD to ground.
*When installing, be sure to ground the product.
The role of constant current circuits
If a surge occurs in the power supply, the surge protection circuit will protect the LED.
If the DC power supply is not fully rectified, AC waves will remain and cause flickering.
Once fully rectified, there will be no flicker.
Flickering can cause eye fatigue
If rectification is incomplete, slight AC waves will remain, causing flickering.
Flickering can cause eye fatigue.
Role of the constant current circuit ①
With a built-in constant current circuit, a constant current always flows through the LED, even if there is a sudden voltage rise (surge).
This ensures that the brightness remains constant at all times. In addition, as the current does not exceed the rated value, deterioration of the LED is prevented, resulting in a longer lifespan.
Role of constant current circuit ②
By removing the waves in the AC, the resulting current is rectified, eliminating flicker and causing less eye fatigue even when used for long periods of time.
