I am very happy with my purchase. The price is great and the bulb is reliable, unlike other bulbs, I have purchased from other sites they burned out right away or were defective in some way. It has a very nice shade of green and gives off a perfect amount of light. I like to use these for significant night time illumination in my home. It allows me to come in and out of the darkroom without taking time for eyes to adjust. I highly recommend them.
