UL CERTIFICATION APPROVED
Donglong Technology have got UL certification for the US market. We applied two series of UL certification, The difference is listed below:
1, UL files no. OOLV2.E364553, The devices covered under this category are incomplete in certain constructional features or restricted in performance capabilities and are intended for use as components of complete equipment submitted for investigation rather than for direct separate installation in the field. This category covers light-emitting-diode (LED) lamps, with a driver or power supply, intended for direct connection to a lampholder for specific luminaires or special applications.
This category also covers LED lamps that require an external driver or power supply for connection to an alternating- or direct-current power source. The products may be marked with additional restrictions regarding the electrical supply.
This category also covers the lamp component of luminaire conversion kits; see Light-emitting-diode Retrofit Luminaire Conversion Kits (IFAR).
These products are intended for connection to lampholders for outlet boxes and lampholders provided in luminaires, portable luminaires and signs. They are provided with industry-standard (e.g., ANSI, IEC) or proprietary lamp bases. ANSI base configurations are covered in standards such asNEMA_ANSLG C81.61, "Electrical Lamp Bases - Specifications for Bases (Caps) for Electric Lamps." When differentiating between low-voltage and line-voltage ANSI lamp bases, consideration is given to Tables 7.3.3.1 and 7.3.3.2 in ANSI/UL 1598, "Luminaires.

Under this UL certification, our tubes can be installed for retrofit or new installation. Not only for the project, but also for selling in the supermarket.
For this series tube, we can achieve 110lm/w, CRI＞80, and we can provide 3 years warranty for 24hours/per day usage. It is excellent in engergy saving.
