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.
Solution: negative
Why? The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, it's a negative review.

New input: First three engines fired great, then I went thru 8 igniters on 4 different engines. My request for a refund was 8 days outside of the 30 day warranty and was denied. Now I have to go thru Estes for support. May want to try another supplier as now I have 47 engines to go through.
