We are a small TV station that uses these bulbs on a daily basis. These lamps seem to last quite long under full load (8 months or more under a full load almost daily). While other bulbs have had to be changed every 3-4 months, this particular brand seems to last longer for whatever reason. As with all incandescent bulbs, there is quite a heat factor but that is to be expected. I will continue to buy them.
