well , I finally receive a new bulb replacement . as I mention in another review of a similar product from another company , this be my second replacement bulb in a year . I decide to try another company this time and so far so good . no problem install it . take less than 5 minute , if that . the picture be great , however , I have this yellowing stain imprint , which I believe be from the other bulb . I be research this and will update in the future when I get a answer . nevertheless , the bulb be work well and be please with it so far . hopefully , this will last much longer than the previous one , which be less than a year old . I plan on update the status of this review in the future , in hope that this will benefit those look for some good insight on this bulb . let 's hope it all good from this point on .
