New from HUMUBAO: Classroom Lighting Retrofit at Heshan No. 1 Middle School — Field Test and Procurement Tips

New Product Highlights Overview

HUMUBAO (HUMUBAO Lighting) has newly launched a classroom-specific LED classroom light, which has completed actual whole-school classroom lighting renovation testing at Heshan No.1 Middle School. Heshan No.1 Middle School is a school with a century-long history and has produced many famous alumni, and the school has extremely strict requirements for the lighting environment. After contacting the factory through channels, we conducted on-site testing at the school immediately and found that the illuminance of the original old bracket lights was seriously insufficient, with the average illuminance on classroom desks less than 200lx, far below the national standard requirements. The school required the entire renovation to be completed during the 7-day National Day holiday, and the schedule was extremely tight; nevertheless, we still delivered successfully and passed the re-test acceptance using our own equipment.

This renovation selected the HMB-J01-36 electroplated grille anti-glare classroom light, with the following core highlights:

• Electroplated grille anti-glare design: Effectively controls glare, improves students' visual comfort, and reduces reflection interference on the blackboard and classroom desks.
• High illuminance uniform output: After renovation, the illuminance on classroom desks is significantly improved, with good uniformity, meeting the lighting needs for classroom reading and writing.
• Suspended rod installation structure: Adapts to the existing classroom ceiling conditions, making construction convenient without damaging the original building structure.
• Fast delivery capability: Completes the entire process of old fixture removal, suspension installation, and commissioning within the holiday window, without affecting normal teaching order.

This product is suitable for educational lighting scenarios such as school classrooms and training rooms, supports batch supply and customized inquiries, and procurement buyers from the education sector are welcome to contact us for discussion.

Core parameters and technical advantages

The classroom lighting renovation of Heshan No.1 Middle School selected the HUMUBAO LED classroom luminaire, model HMB-J01-36, featuring an electroplated grille anti-glare design. This product is optimized for the core requirements of glare control, illuminance uniformity and long-term stability in educational lighting scenarios, and is suitable for long-time reading and writing environments such as school classrooms, laboratories and libraries.

In on-site measurements at Heshan No.1 Middle School, the illuminance of old bracket lamps in classrooms before renovation was less than 200lx, far below the national standard requirement for maintained average illuminance on classroom desks. After replacing with HMB-J01-36, we used our own testing equipment to measure the classroom desk and blackboard areas on site. Illuminance uniformity and glare control both met the relevant standards for educational lighting, and the overall light environment was significantly improved.

The core advantages of this product include:

• Electroplated grille anti-glare structure reduces direct glare interference when students look up;
• The rectangular light-emitting surface combined with suspended rod installation provides more uniform light coverage, avoiding local over-brightness or under-brightness;
• The LED light source offers high luminous efficacy and low energy consumption, suitable for long-term high-frequency use in schools;
• The luminaire structure is sturdy and adapts to existing classroom ceiling conditions, facilitating batch renovation construction.

For school and education system buyers, HMB-J01-36 achieves a good balance among anti-glare performance, illuminance uniformity and installation adaptability, making it one of the models worth prioritizing in classroom lighting upgrade and renovation.

Application scenarios and installation methods

The HUMUBAO classroom lighting solution is suitable for ordinary classrooms, multi-function classrooms, laboratories, library reading areas and multimedia teaching spaces in primary and secondary schools, and is especially suited to existing campus renovation projects that must be completed without disrupting normal teaching. Take Heshan No. 1 Middle School as an example: as a century-old school, its classrooms had severely aged batten luminaires with measured illuminance below 200 lx, and the school required the entire renovation to be completed during the National Day holiday. The construction team carried out nighttime suspension installation, removing the old luminaires and installing the new ones without altering the main trunk of the existing wiring, and normal classes resumed right after the holiday.

This renovation used the HMB-J01-36 electroplated grille anti-glare classroom luminaire, installed with suspension rods. The luminaire is rectangular with a uniform light-emitting surface, effectively controlling glare and improving desktop illuminance uniformity. The installation supports the following two common scenarios:

• New or fully renovated classrooms:Preset suspension rod points according to classroom length and width and desk layout, and arrange the luminaires with their long sides parallel to the blackboard to ensure uniform illuminance on desks and the blackboard surface.
• Renovation of existing classrooms:Reuse the original suspension holes or wiring routes to reduce drilling and cabling work, making it suitable for concentrated construction during short holiday schedules.

For overseas B2B buyers, this product can adapt to various classroom ceiling heights and ceiling structures, and installation accessories can be supplied as a package according to project requirements, facilitating unified construction organization by schools or contractors.

Upgrade differences of similar products

The original classroom lighting at Heshan No.1 Middle School used an early batten luminaire solution, with measured illuminance below 200lx, and the luminaires were severely aged with obvious light decay. This renovation selected the HUMUBAO model HMB-J01-36 electroplated grille anti-glare classroom luminaire. Compared with common similar products on the market, the upgrade differences are mainly reflected in three aspects: optical structure, installation adaptability, and long-term maintenance.

Compared with ordinary LED classroom lights, the core difference of HMB-J01-36 lies in the electroplated grille anti-glare design. Ordinary products mostly rely on diffuser plates to reduce glare, but often at the cost of light output efficiency; the electroplated grille controls glare while maintaining a uniform luminous surface, making it more suitable for prolonged reading and blackboard-writing scenarios. For school buyers, this means a more comfortable light environment at the same power, reducing students' visual fatigue.

In addition, this renovation was completed during the National Day holiday, with the contractor using nighttime hoisting operations to carry out demolition and installation simultaneously. The pendant mounting method of HMB-J01-36 matches the original classroom structure closely, reducing on-site renovation workload, which is a practical difference easily overlooked in similar product upgrades yet directly affecting the construction schedule.

Certification, warranty and packaging

For school and education-system procurement, HUMUBAO treats compliance and traceability as delivery prerequisites.
