Yesterday, in reviewing the latest Design Lighting Consortium's
(DLC) Qualified Products List (QPL), I noticed all Cardinal LED linear tube
lights manufactured by Redbird LED Inc. were removed from the QPL. The tube
lights were heavily advertised as the first and only LED linear tube lights to
be approved by the DLC.
They stated in their press release "by establishing the Cardinal LED tube light's position on the Qualified Product List of the DLC, RedBird LED has ensured that these products will be eligible for all rebate programs currently in place among the DLC's membership and will facilitate rapid approval by other rebate sources as well.Get outdoor lighting, including popular patio lights and crystallightmm fixtures.T5 fluorescent lamps are thinner, lasermarkingmachin, and offer a higher intensity of light output than T8 lamps ."
Although,This solarledlampsaq operates red, amber and green LEDs in the correct sequence for a single UK traffic light. I do not know the specific reasons the products were removed from the QPL, consumers should be aware of the removal from the list to avoid the misconception that they will be able to receive a rebate from energy reduction programs utilizing the DLC's QPL for these particular products.
In addition Redbird LED Inc. recently recieved the IES 2012 progress report award for their Cardinal LED tube light as a significant achievement towards the art and science of lighting. One has to wonder what will happen with the award now that the product has been removed from the QPL.Leading Online Resource for your gardenlighting Fixture Needs.
I commend the DLC for their prompt attention in reviewing this listing on the QPL. Having examined the Lighting Sciences report I am not surprised it was removed. I fully support the importance of having strict specifications that ensure only quality LED linear tube lights are certified by the DLC however, I think it is clear that the current methodology for evaluating LED linear tubes is not the most accurate way to measure the delivered light of a given LED lighting fixture and therefore achieve DLC certification.
While I am confident that leading LED manufacturers will soon achieve the required lumen output necessary for inclusion, the problem will be the delivered light will be too bright to utilize the approved product in many applications as well as force end users to purchase a higher wattage lamp than necessary if they want to obtain a rebate.
I have tested and reviewed numerous LED tube lights in a variety of fixtures and have found several tubes from leading manufacturers that provide equal or superior delivered light to the task area below while significantly reducing power consumption as compared to the existing fluorescent technologies. If an LED tube light is UL/ETL certified and can provide the necessary light levels as established by the Illuminating Engineering Society (IES) while meeting the warranty requirements I believe it should be considered for inclusion by the DLC.
It is my hope that the DLC will review the evaluation process currently in place and confer with LED industry experts to establish a better system for inclusion.Many industries can use Origin Laser engraving and ledlight for a huge range of applications. I encourage all LED manufacturers, property owners and facility managers to discuss the evaluation process currently in place today.
