DesignLIghts Consortium Certifies 18 watt LED Replacement Lamp from RedBird LED

Culminating several years of development and testing, the Cardinal™ LEDLinear Replacement Lamp has become both the first, second, and still the only LED tube light in the world to receive DLC Certification. With the recent addition of two more of RedBird LED’s Linear Replacement Lamp products on the DLC Qualified Product List, it is noteworthy that they are all in the top 1% when it comes to efficacy. When the 12,160 LED lighting products on the DLC Qualified Product List are sorted for efficacy as measured in lumens/watt, the RedBird LED products come in with four out of the top twelve slots at 3rd, 7th, 10th and 12th highest efficacy.


The new DLC Certification covers the 18 watt models at both 4100K and 5000K CCTs.  The 18 watt linear replacement lamp is the most popular model used for one to one fluorescent lightingretrofits of standard 32 watt T8 or 40 watt T12 fluorescent lamps. When retrofitting with a Cardinal LED tube the user will expect to save as much as 55% on their energy consumption when compared to a standard 40 watt T12 model or 40% on a 32 watt T8. With this level of savings and the rebates available, the customer can see paybacks as low as 9 months in many states.  

Jonathan Eppstein, President of RedBird LED commented, “While we were ecstatic to have been the first, and only LED Linear Replacement Lamp to have qualified for DLC Certification with our 22 watt product in May, the DLC Certification for our 18 watt lamp is an even more exciting event. We expect the DLC Certification of the 18 watt Cardinal Lamp to dramatically increase the adoption and deployment of this breakthrough product.  Having both our 22 and 18 watt LED tubes on the DLC Qualified Product List solidifies our position as the market leader in this sector of the LED lighting industry.”
