Pay attention to! New solid state lighting products standard V4.2 deposit four points change

United States time on April 28, 2017, DLC officially released the solid state lighting product standard V4.2 version of the technical requirements. As the most influential commercial lighting product performance certification standards in North America, DLC certification has great influence on the design and sale of commercial lighting products exported to the United states. Compared to the previous version of the technical specification V4.1, the new version of the V4.2 has four new changes worthy of attention.

Test and documentation requirements for new lighting fixtures in hazardous areas

Hazardous lighting fixtures can be applied in accordance with the main categories (primary use), or special (specialty) categories.

In the DLC version of V4.2, if the manufacturer through special categories of applications (including outdoor wall, square, floodlights and indoor high roof mining lamp main categories, apply for special categories of dangerous places, lighting) must meet additional documentation requirements. The specific requirements for the product through special classes do not apply for hazardous place lighting certification, must provide to meet the UL844 certification compliance documents, including product certification level and classification. If the product in accordance with the existing main categories (primary use) to apply, do not apply in accordance with Specialty, you do not need to meet the requirements.

New lamp category

Please note that only the LED lamp with the lamp holder is suitable for the requirements of the LED DLC replacement lamps. Without the lamp holder of the lamp is considered as a refurbished DLC kit, not within the scope of the discussion. In the old standard, DLC currently recognized 0.6 m, 1.2 m LED lamp and U tube. In the DLC V 4.2 version, DLC will be required to split the 1.2 meter lamp into the specific requirements of the three categories of products:

1.2 m LED replace T8 tube

The product must be 48 inches long and use the G13 lamp holder, any manufacturer must declare that the material is replaced with the same length of T8 fluorescent tube. DLC does not allow manufacturers to claim to replace other lengths or diameters of fluorescent tubes, such as a T8 LED lamp to replace the T12 fluorescent tube, which is not allowed.

1.2 m LED replace T5 tube

The product must be 46 inches long and use the G5 lamp holder, any manufacturer must declare that the material is replaced with the same length of T5 fluorescent tube. DLC does not allow manufacturers to replace fluorescent tubes with other lengths, lamp caps, or diameters.

1.2 m LED replace T5HO tube

The product must be 46 inches long and use the G5 lamp holder, any manufacturer must declare that the material is replaced with the same length of T5HO fluorescent tube. DLC does not allow manufacturers to replace fluorescent tubes with other lengths, lamp caps, or diameters.

The following table is a requirement for all bare tubes after the 4.2 revision:

Be careful

According to Type A T5 and T5HO DLC tube, forced ballast factor 1 electronic programmed-start collocation ballast test, and the reported value must be submitted when power power combination lamp and ballast, and the lamp power is not bare.

T5 replace the lamp also need to be equipped with lamps and lanterns to do the light level photometric test. Ordinary T5 tube test and T8 lamp no difference. The difference lies in the need for the use of a special T5HO lamp casing, and if it is Type A/B or Dual mode 1.2 m T5HO lamp, you need to use the test with the shell with 4 lamps. If it is Type T5HO C lamp, DLC currently only recognized a drag three, a drag of the four and one of the 63 programs.

T5HO has different light efficiency, luminous flux and light distribution requirements, see the detailed version of DLC V4.2.

New light efficiency tolerance requirements

The policy to reduce the high visibility, low color temperature products, light efficiency requirements. The conditions to be met and the adjustment of the luminous efficiency are as follows:

The percentage of the above reduction is not cumulative, and the maximum percentage is applied to multiple conditions. If you need to use the performance tolerance to meet the standards, the calculation method is to use the standard optical efficiency requirements to calculate the percentage of color concessions, and then determine the allowable tolerance (3%).

Adjustment of mixed LED policy

In the DLC version of the V4.2, the modified hybrid LED policy (Multiple LED Policy), DLC accepts the same LED PCB on the hybrid LED, but the number of each LED must be fixed, and can not be dynamically controlled adjustment.

Product type to upgrade:

The following products must be re submitted before the release of the 4.2 version, otherwise it will be removed in July 28, 2017:

1) use a special category (specialty) to submit a product containing the Hazardous word application. The manufacturer needs to apply for the updated name list within three months after the release of 4.2 and requires DLC audit. The application DLC does not charge, according to the normal audit cycle calculation.

2) T5 and T5HO lamp, LED lamp for 1.2 meters in the class before, need to update the listing before July 28th, to meet the new standards. DLC to apply for a normal delivery fee, according to the normal audit cycle.

Transition schedule:

In May 19, 2017, for related to the dangerous places of lighting products and T5, T5HO lamp, DLC can still accept the use of the DLC V4.1 version of the audit, but must upgrade to DLC V4.2 version before July 28th, otherwise it will be removed from the list.

For light efficiency concessions, DLC will automatically apply to the products listed in April 1, 2017. If you have the products listed as DLC standard light efficiency upgrade, resulting in this year is about to be removed the names, but the use of concessions DLC version 4.2 can meet the requirements of the current light effect DLC, DLC will automatically maintain the column name. All other products that are applied before the release of the DLC V4.2 Standard Version, if they do not meet the requirements of the light efficiency, but the use of concessions can be qualified, then you can re submit the DLC application, the need for
