Review on Bioluz LED Light Bulbs 6 Pack: Illuminating Energy Efficiency and Value! by Shannon Cool

June 23rd, 2016 I purchased 6 6w bulbs (40w equivalent) from Revain and installed 4 of them in a fully enclosed pedestal light fixture that was purchased at A backyard wall was mounted outside of our front yard. The lights are connected to a photocell sensor that turns the light on at dusk and off at dawn. Night hours change with the season, but let's say conservatively that the lights are on from 6pm to 6am or 12pm (I think they're on less than that, but I'd like to speak conservatively for LED -Light). In July 2017 1 out of 4 original headlights burned out (the light worked about 1 year and 1 month). That means the light lasted 4750 hours based on 12 hours per day x (365 days per year / 12 months per year) x 13 months. These bulbs are said to have an average lifespan of 25,000 hours according to this list, so I attributed that short lifespan to poor light. My second lightbulb just burned out on September 5th, 2017. This second lamp performed slightly better and, again conservatively, lasted about 1 year and 3 months. That means the second light lasted 5475 hours based on 12 hours per day x (365 days per year / 12 months per year) x 15 months. I can no longer attribute it to another bad light. 2 out of 4 original bulbs will burn out in just 1/5 of their lifespan based on this average lifespan. I would say that these lamps do not meet manufacturer Bioluz specifications and I would advise anyone wishing to purchase these lamps to look instead for another supplier who can provide an actual average lifespan that matches market specifications. In the future I will not buy LEDs from this brand again. I went through my entire pack of 6 bulbs on 4 lights in just over a year. I will use a different brand over time and I suggest others do the same.
