Construction green 6-line laser level 360° Huepar B21CG + case
Looking for ultimate precision for your construction or renovation projects? The Huepar B21CG 6-Line Green Laser Level 360 + Case is a professional tool that sets new standards in leveling. With its advanced green laser beam technology, exceptional visibility, and robust design, this level is an indispensable tool for tiling, drywall installation, leveling walls, installing furniture, and many other demanding jobs.
Thanks to the innovative projection system, which includes one 360-degree horizontal line and two vertical lines, you will easily cover the floor, walls and ceiling of an entire room at once. Forget about time-consuming manual measurements and inefficient classic spirit levels - with this professional laser level you will get the job done faster, more accurately and with significantly less effort.
Key benefits and exceptional functionality
Superior visibility with German Osram technology
The Huepar B21CG level is equipped with a top-quality green laser unit from the renowned manufacturer Osram. Green laser light is up to 4 times more visible to the human eye than standard red light at the same power. This allows you to work undisturbed even in brighter rooms or at greater distances. The device offers a working range of up to 85 feet (approximately 26 meters) at 300 LUX light, and using a special pulse mode and laser receiver, this range is extended up to 200 feet (approximately 60 meters).
Smart self-leveling and manual mode
The level offers two operating modes that cover all needs on the construction site:

Self-leveling mode: When the pendulum is unlocked, the device automatically levels itself within ±4° in just 3 seconds. If the tilt is greater, the laser beam flashes to alert you to the abnormality.
Manual (locked) mode: When the pendulum is locked, you can fix the laser lines at any angle. This is ideal for laying stairs, diagonal lines or installing sloped ceilings.

Uninterrupted operation and modern Type-C charging
Forget about constantly changing conventional batteries. The device is powered by a high-capacity 3.7 V / 5200 mAh lithium-ion battery, which provides up to 8 hours of continuous operation with all beams turned on. The battery has its own Type-C charging port, which means you can charge it separately. If your battery runs out while you are working, you can simply connect the leveler directly to the mains or a portable battery (powerbank) and continue creating.

Frequently Asked Questions (FAQ)
Can I use this laser level outside in bright sunlight?
Yes. The Osram green laser is significantly brighter than the red laser, which improves visibility outdoors. For optimal performance at a distance and in bright sunlight, we recommend using the external pulse mode in combination with a Huepar laser receiver (e.g. LR-5RG or LR-6RG), which extends the range of the device up to 200 feet (approximately 60 meters).
Can I use the device while the battery is charging?
Of course. The level supports direct power supply via the Type-C charging cable. If the battery runs out, you can simply remove it or leave it in the device and connect the level directly to the mains voltage or a portable battery (powerbank) to continue working without interruption.
How does a pendulum lock work and why is it useful?
When you move the switch to the lock position, the pendulum is fixed. This prevents damage to the sensitive self-leveling mechanism during transport. At the same time, this mode allows you to tilt the device at will and project straight lines at any angle, which is extremely useful when installing staircases, railings or sloping attic structures.
WARNING: Never point the laser beam directly into the eyes. The device is classified as a laser class 2 according to IEC/EN60825-1/2014. The device is safe to use when basic safety instructions are followed without the need for additional protective equipment.

Same summary

The Huepar green 6-line construction laser level 360 + case is particularly suitable for users who perform precise assembly and construction work where clear and clearly visible lines in multiple directions are required. Due to its 6 lines, it allows for greater possibilities when erecting structures, laying tiles or performing internal and external alignments. This type of model makes sense mainly for home craftsmen and for small or medium-sized renovations, as well as for more demanding tasks where basic single-line levels are not sufficient. Given its universality, it is suitable for most domestic tasks, but may not be the optimal choice for very specific industrial requirements.
