In 2014, my bearded dragon had gotten metabolic disorder from a poor UVB bulb. I was a first-time dragon owner. I was recommended the Arcadia D3+ lamp by a very knowledgeable beardie owner. With proper care and the Arcada lamp - she made a full recovery. I have been a fan ever since. My dragons thrive with these lamps (I purchase the T5-22in). However, it is not just the great products - but also the great service from Todd Goode, the Lightyourreptile.com owner. He has made a video to walk me through assembly instructions. I recently had a damaged product and he replaced it right away. Very easy to do business with and very supportive. There are no downsides to the products and service. Highly recommend!
