Ulanzi LT028: The Portable COB Light That Combines Power and Mobility

Introduction

In the world of content creation, what often makes the difference is not just the camera or the lens, but how you light your scene. Even with great ideas, if your lighting is limited, your photos and videos may not look as they should. That’s where the Ulanzi LT028 comes in — a 40 W bi-color COB LED light with a built-in battery, designed for creators who need mobility, versatility, and professional results without carrying too much gear. In this blog, we’ll explore what it offers, what it can really do, its strengths, and its limitations, to help you decide if it’s worth it for your projects.

Specifications and Technical Properties

Based on official reviews and independent tests:

Feature	Details	Real-World Impact
Power	40 W bi-color COB LED	Enough light for mid-shots, interviews, indoor videos; solid output without overloading your kit
Color Temperature	Adjustable 2500 K – 6500 K	Switch between warm (yellowish) and daylight (cooler), useful for matching ambient light or setting mood
Color Index (CRI/TLCI)	≥ 95 / ≥ 96	Accurate color reproduction; natural skin tones; less color correction needed in post
Power Source	Built-in 3400 mAh battery; can also be powered by AC/DC adapter	Huge advantage for outdoor shoots or places without outlets; battery gives decent autonomy
Battery Life	Up to ~75 minutes at 100% brightness; longer if dimmed; recharges in ~3 hours	Enough for medium recording sessions; plan extra batteries/charging for long shoots
Size & Weight	~10.5 × 8.5 × 8.5 cm; ≈ 460 g	Compact and portable; light for travel setups; can be mounted on arm, tripod, or light rig
Mount & Modifiers	Mini Bowens mount; includes mini reflector and dome diffuser	Flexibility to soften and shape light; improves aesthetic results

Key Advantages

Portable yet powerful: rare to find 40 W output in such a compact, battery-powered form. Perfect for mobile creators.
Light quality: high color fidelity, natural skin tones, diffuser and reflector included for softer light.
Versatility: runs on battery or AC; adjustable brightness and temperature; creative effects for atmosphere.
Good value: affordable compared to large studio lights, strong price-performance balance.

Limitations / Things to Keep in Mind

Not as powerful as big studio lights: may need support lights or modifiers in bright outdoor setups.
Output loss with modifiers: reflector/dome reduces intensity, so close positioning or higher output is needed for some shots.
Battery life: ~75 minutes at full power; manageable but extra planning required for long sessions.
Build materials: plastic housing less rugged than high-end lights; mini Bowens mount can limit heavier modifiers.
Mini Bowens only: doesn’t support full-size Bowens modifiers without adapters.

Practical Use Cases

Vlogs / indoor content: 50–70% power with diffuser for soft, flattering face light.
Small product photography: light objects and textures; diffuser reduces reflections.
Review/demo videos: adjust temperature and effects to create specific moods.
Outdoor shoots at dusk/shade: portable fill light powered by internal battery.

Conclusion

The Ulanzi LT028 is a well-thought-out light for creators who value mobility, good light quality, flexibility, and strong results without investing in bulky studio gear. For lightweight setups, quick shoots, social media content, or product photography, it performs very well.

It’s not the best choice for massive productions or situations requiring strong long-distance light, but for most creators, its size, autonomy, and light quality make it a valuable tool.

👉 At Visión Creativa, we believe the LT028 is an excellent option if your priority is improving your lighting without complications: with one portable panel, you can significantly elevate your photos and videos, achieving softer, balanced, and more professional-looking light.
