Bioluz LED4 Pack PAR38 LED Light Bulb 90 CRI 12W = 100-120 Watt Replacement, Soft White 3000K, Dimmable Light Bulbs Flood Lights Outdoor/Indoor UL Listed Light Bulbs Title 20 High Efficacy LED Bulbs

BRIGHT, focused, spot light...like a good flashlight. Purchased and installed 4 liked them so much I bought 4 more. Used 6 in fixtures with no cowels (light guards) mounted 6 inches below 12 inch eaves on 3 sides of my house. On at dusk off at dawn, 365 nights for 6 1/2 YEARS!! In Michigan's rain snow and freezing weather, not one failed! After 2 years I bought another case of 4 just to stick away. Might have to Will those to someone! I was using brand name Halogen SPOT LIGHTS and drawingclose to 100 Watts EACH and having to replace one or two a year; any time rain hit hot glass, at $7.97 a "Pop". These are so cool burning that the L.E.D's and accompanying circuits are housed partly in plastic. I didn't like the feel of them and thought "Duped Again" on unboxing. I worried that the construction couldn't be watertight like an all glass bulb...WRONG.! I moved to the country on 5 acres outside a small village after living in crime ridden L. A. Then on to drug riddled small town Georgia where EVERYTHING not anchored securely, "floated" away with the nightly tides of a steady crime wave... Nothing of mine has been touched here after more than a DECADE! I attribute that to the landing lights everyone approaching has to squint to see past. One caution though; they do attract people in distress. I've assisted several times when someone has run off the road into a snowbank or hit a tree and walked past my neighbors houses to mine, like moths to a flame to make it to their perceived safety of my well lit Sanctuary. These draw less than 15 Watts, put out more light than florescent or halogen bulbs drawing a budget busting amount of power! My peace of mind, their longevity and affordable cost to both purchase and to power, make these...well...I don't have the words...

Like the brightness and the light weight of the bulbs. Will see in a few years how they perform.

Works very well in my Kitchen

Generally good. Lamps work as promised and Bioluz has a detailed list of dimmers for each of their lamps on their website which was accurate for the two types of lamps I tried. Two quibbles: (1) these lamps are often used in ceiling down cans, often quite high up. The usual tool for installing lamps like these is a long pole with a suction cup to hold the bulb. But these bulbs have a "wave" pattern of scoring on the outside of the glass, so suction cups won't grip the bulb. I got the old bulbs out with no problem but had to hire someone with a tall ladder to install the new ones. Probably this wave pattern is to improve the light scatter of the bulb, but it would be better if it were on the *inside* of the bulb. In my case, the guy with the tall ladder (18ft!) cost more than the 4 bulbs! (2) These bulbs dim well. But as with most LED bulbs, the light temperature doesn't change as they are dimmed (incandescent bulbs usually "warm" slightly as they dim), I find the high (daylight) color of these bulbs when dimmed a little odd. Maybe I'll get used to it in time.

These bulbs render color incredibly well. The red end of the spectrum is also great for plants. The build quality is impressive. I use these to grow plants in a 36” deep aquarium. I also use them in our outdoor floodlight fixtures. The colors are much more accurate on the security cameras.

Good price and good quality

Liked led flood lights . Good deal for 8. Will buy again

Update: Seller does list a 3 yr warranty for their similar BR40 27000K bulbs. Contacted them regarding these and they have a 3 yr warranty also and they replaced the 2 bulbs with no hassle. Raised the rating 1 star for their excellent service. Possibly the bulbs last longer in less cold areas than interior Alaska.Used 4 outdoors. With very limited use 2 stopped working. Used them in outdoor motion detectors and were on for no more than an average of 1/2 hour/day over a period of about 12-18 months. Bioluz claims a life of 23 years at 3 hours/day. Not even close. Notably they do not show any warranty at all for their bulbs. Bulbs are also relatively heavy. Put out good bright light while they last.
