Hangzhou, China – December 12, 2024 – Hangzhou G-Sun Lighting Co., Ltd., a professional lighting company founded in 2000 and located in Jingshan Town, has today announced the launch of a new automated sorting and inspection system for bulb casings. This system is designed to improve production consistency for a wide range of specialty lighting products. The company also confirmed that recent investments in green manufacturing processes have significantly reduced energy consumption during assembly and packaging.
The new sorting line is part of a broader effort to strengthen quality control from raw material receiving to final packing. According to the technical department, the system uses optical sensors and weight verification to separate components that do not meet dimensional or surface quality standards. This step is especially important for
decorative light bulbs, where visual appearance and uniform coating directly affect customer satisfaction. With the new equipment, G-Sun Lighting can process casing batches faster while keeping defect rates below 0.2 percent.
Another major improvement involves the assembly of
LED Bulbs Edison Bulb style products. These retro‑design bulbs have become highly popular in North American and European markets. By fine‑tuning the soldering process for LED strips inside the glass envelope, the engineering team has achieved a more stable thermal path. This leads to longer rated life and better performance under frequent switching conditions. The company states that the updated production method also reduces material waste because fewer units fail during the initial burn‑in test.
G‑Sun Lighting has also upgraded its testing protocols for
Infrared Light Bulb series. These bulbs are widely used in animal husbandry, food warming, and industrial drying applications. The new testing stations monitor wavelength stability and surface temperature distribution over a continuous 72‑hour run. Early results show a 12 percent improvement in heat consistency compared to previous batches. Customers in Australia and Mexico have already placed repeat orders for this improved infrared series.
In response to growing demand for outdoor and fishing equipment, the factory has dedicated a separate assembly line to the
Fishing Light Bulb category. These bulbs need to resist moisture, vibration, and sudden temperature changes. The new line applies an extra sealing layer over the solder joints and uses a reinforced glass envelope. A recent shipment of fishing bulbs to Japan passed a 500‑hour salt spray test with no visible corrosion. The company plans to extend this sealed construction to selected marine and greenhouse lighting products next quarter.
For general illumination markets, G‑Sun Lighting continues to expand its range of standard
Light Bulbs with improved luminous efficacy. By adopting a more efficient driver design and advanced phosphor coating, the latest A‑series bulbs achieve 130 lumens per watt while maintaining a colour rendering index above 80. These bulbs are fully compliant with RoHS and CE requirements. The company’s internal lifecycle assessment shows that the new bulbs use 18 percent less energy over their rated lifetime compared to models produced two years ago.
The production floor has also been reorganized to reduce unnecessary walking and handling. The casing sorting station now feeds directly into the soldering and sealing zones, which shortens the distance that components travel. Operators receive real‑time guidance from a central display that shows target output and quality metrics. This lean layout has already increased the overall equipment effectiveness by nine percentage points since the beginning of the fourth quarter.
All these improvements are supported by G‑Sun Lighting’s integrated management system, which is certified to ISO 9001:2015. The company performs internal audits every two months to ensure that process changes do not introduce new risks. A full‑time environmental team monitors wastewater and soldering fume extraction to keep emissions well below local limits. The facility also runs an energy management system that tracks electricity use per thousand bulbs produced. Data from November shows a 7 percent drop in energy intensity compared to the same month last year.
Looking forward, G‑Sun Lighting plans to launch a new collection of smart‑compatible bulbs before the third quarter of next year. These bulbs will feature adjustable colour temperature and wireless dimming while retaining the mechanical durability that customers expect from the company’s existing product lines. The research and development team is currently testing four different antenna designs to find the best balance between range and power consumption.
The company invites existing and potential customers to contact the sales department for technical samples of the improved Decorative Light Bulbs, LED Bulbs Edison Bulb, Infrared Light Bulb, Fishing Light Bulb, and other Light Bulbs. Sample lead time is currently five to seven working days for standard specifications. Volume orders can be shipped through Shanghai or Ningbo ports, with full container load consolidation services available.
