Application Examples

Our Excalibur Mini-Series is excellent for a multitude of environments, check out the application examples below:

Kaye AKA LateBloomer just switched over to our Excalibur Mini Series to give her better coverage over her 48inch area. Using our reflectors offers a higher amount of PPFD directly under the fixture by reflecting the light that normally would be lost, back down onto the plant canopy. Kaye has an incredible amount of knowledge and is a pleasure to watch! Give her a like and subscribe to help build the Grow-It-LED community!

Sacred Skunk Organics is enjoying the combination of our Excalibur Mini’s and Cool Cobs in one tent. For drawing such a low wattage the light levels are incredibly high, his plants and bank account will thank him. Switching to LED in his no-till organic tent reduces the electricity bill along with providing proper full-spectrum over the older ‘blurple’ led fixture he was using before. You know the ones, half of the LEDs burn out, it’s hot and the plants just aren’t happy.


Another excellent example is from a local grower who was having difficulties in the winter months dealing with low light levels associated with the 8′ 4 lamp T5 fixtures. In this application, you can see the Excalibur mini fixtures on the right and the 8′ T5 on the left. On average a 4 lamp t5 should use about 216w, while 2 Excalibur Mini’s use only 45w a piece. with a savings of over 100w per light, while producing MORE light, it’s a no brainer to throw those old T5’s away and switch to the Excalibur Mini’s.


Our good friend at tipsonthetrees303 has been around from the start, giving us quality content to help boost our platform. He offers really good tips and tricks for growing cannabis along with some amazing content! We sent over the Red Excalibur Mini fixture for him to try out and report back his findings. Seems like the plants are enjoying the supplemental lighting!

    Love these! They were well worth the investment. All my seedlings were healthy, green, and stout. They make very little heat and were easy to hang and turn on and off.

    Love these fixtures! There are not many quality 2-foot fixtures around that can fit into small closets & spaces. Compared to the Fluence “Ray” fixture, this light is cheaper, more efficient, better spectrum w/ Samsung L2 (recommended). Integrated driver is easier to hang & move around.

    Also this uses modular construction, it’s easy to see how you could use the frame to install a new driver & LED strip in the future instead of buying new ones and using up more materials & energy. Very well built. Feels like you a buying a light made by a craftsman. Build quality visibly higher than other LED companies.
