Photo lamp Puluz PU4140 132-LED adjustable brightness for studio and on-camera lighting

Puluz PU4140 132‑LED photo lamp designed for studio and on‑camera use provides continuous, adjustable light for photography and video. With a high CRI of 95+, the lamp ensures faithful color reproduction essential for product photography, portrait work, video recording and live streaming. The compact body houses an 8W light source with a wide 120° beam angle that delivers even illumination and reduces harsh shadows and hotspots.

Advantages

The lamp combines 132 LEDs (44 cool white, 44 warm white and 44 RGB) to offer a broad color temperature range from 2500K to 9000K and full RGB control (0–360°) for color, saturation and brightness. It provides smooth dimming from 0 to 100% and includes up to 20 built‑in lighting effects such as lightning, fireworks and candle flicker. A built‑in 2600 mAh rechargeable battery supports portable use with approximately 70 minutes of continuous operation at maximum brightness and recharges in about 2 hours via USB‑C (5V/2A).

Recommendations

For accurate color work, set the lamp to the appropriate color temperature (2500K–9000K) and verify white balance in camera. Use CRI 95+ daylight settings for product and portrait shots to minimize post‑processing. When working outdoors, bring a power bank or charger to extend operating time beyond the built‑in battery.
