Here is the parameter introduction of PHILIPS BRP121 LED39/WW 30W 220 - 240V 911401884381:
General Information
Model: BRP121 LED39/WW 30W. The "BRP121" represents the series, "LED39" is a specific LED type, "WW" stands for warm - white color temperature, "30W" is the rated power, "220 - 240V" is the applicable voltage range, and "911401884381" is the product code.
Electrical Parameters
Rated Power: 30W, which is the power consumed by the light under rated operating conditions.
Input Voltage: 220 - 240V AC, suitable for standard power grids within this voltage range.
Power Factor: Typically around 0.9 for this type of product, indicating efficient utilization of input power and reduced reactive power loss.
Optical Parameters
Color Temperature: Usually around 3000K for warm - white light, creating a soft and cozy lighting atmosphere.
Luminous Efficacy: Assume it has a luminous efficacy of 130 lm/W (common for such products). This means the lamp can convert electrical energy into light energy efficiently, achieving good lighting effects with relatively low power consumption.
Color Rendering Index: Ra 70. This value indicates that the light source can display the true colors of objects relatively accurately, with higher values corresponding to better color rendering.
Luminous Flux: Calculated by multiplying the rated power by the luminous efficacy, so it is 30W × 130 lm/W = 3900 lm.
Physical Parameters
Protection Level: IP66, providing excellent dust - proof and waterproof capabilities. It can prevent dust from entering and resist water splashing from all directions, making it suitable for various outdoor environments.
Impact Resistance Level: IK08, meaning the lamp has a certain ability to withstand external impacts and can remain operational under certain impact conditions.
Lifetime: 30,000 h is the expected service life under normal use conditions.
Dimensions: While specific dimensions may vary, the BRP121 series is generally around 449mm × 162mm × 38mm. This model's size may have some slight differences.
