Q: These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
A: 1
Rationale: The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, he gave 1 star to the review considering it extremely poor
Q: I bought the RGB+WW units to install in the steps of my composite deck. They were very easy to install and look great. They are very bright and have held up to the weather quite nicely. I have them dimmed down as low as possible, and they are still a little bit too bright for the steps, but they do the job and look really good. It would be nice if they made a model specifically designed just for steps that would angle the LED light field down instead of straight out. It would also be nice to see the finish available in a darker version, like bronze.
