150W Equivalent Bright White (3000K) PAR38 Dimmable Exceptional Light Quality LED 40 Degree Flood Light Bulb

Bulb is fine at 100% brightness but if you’re looking for something that can dim somewhat like a “normal” bulb, this isn’t for you. Unfortunately had to return due to the weird dimming—see photo— this is fully dimmed, LED bulb in the middle, halogen bulbs on each side.

I used two of these to light the front of my porch for Christmas. The lights were exposed to weather for about a month. They worked fine, and provided a good quality white light during that time.

Bought 5 of these to replace halogen flood lights currently using. Intended to put 2 on side of house and 2 in flood lights for Christmas displays with one spare. Replaced the 2 at ground level with holder like one in attached photo and after first snow, one bulb had died and the other had a bright/low pulsing like something was wrong with it. Unplugged, dried, and cleaned the holders and the one semi working bulb. Put them out with a 3rd bulb--both seemed fine again. About 2 weeks later, had heavy rainstorm and again noticed one pulsing and the other very dim. Again unplugged. Brought them inside and noticed water under the cover of both (there's like a rubbery cover over the bulbs). Left them inside to dry but when tried them a day later, both were dead. Put halogens back in and everything works with them. Returned three dead ones and the 2 never used back to the store. Three had died in less than a month and package gave a 10 year satisifcation warranty. Never tried them in the floodlights on the side of the house. Am surprised because these have so many positive reviews which is why I bought them. However, I noticed one other negative reviewer had exact same experience I did and used a similiar ground level adapter. I think the problem is that they really aren't as weatherproof as they claim. Perhaps if you have them under an awning, you might have more success but in a socket like used for holiday displays, they definitely weren't weatherproof and is what I believe caused them to fail. The angle of the bulb in that type of socket might also be more condusive to water getting inside the bulb if it's not truly sealed whereas one at a higher level angled down will cause the water to flow away from the bulb.

Excellent. Lights up my 60’ evergreen trees and house

I replaced a halogen flood light with the Cree LED in an outdoor "ground" level floodlight holder. The color was good etc but after a few weeks the Cree failed - water droplets were visible on the glass and there was some power looking residue on the socket screws. I cleaned the floodlight holder and put the halogen back in and all is working find. Not sure what the problem was but I expected more than a few weeks!

Nice light, reaches my flag and displays it perfectly over night.

Installed two in a dual exterior fixture. These are very bright covering the deck and backyard while being very efficient. The light is a pleasant color, not the cold blue commonly seen with extra bright LEDs. At some point, I will also replace the two LED floods over the garage. While those older LED floods are fine, the Cree is so much brighter as LED technology has improved.

I bought both the flood and spot CREE 120w PAR38 LED lights to use as a portable work light. Both work great for this purpose and I am happy with the 120w. I think 150w inside would have been a bit of overkill for this purpose. Naturally, the flood shines a wider area of light (40 degrees) vs the spot (25 degrees) as noted on box. Hopefully attached images help for your application. Lamp is ~8ft from highlighted wall. I also added link to "Beam Spread Pocket Guide." Basically, if you need focused light for highlighting, use a spot. For wider area, use a flood. https://www.destinationlighting.com/fliptheswitch/beam-spread-guide/

Great!

This is the highest quality light bulb that I have found for outdoor use. I have 8 upward facing lighting sockets projecting nightly onto the house and this exposes the bulbs to the harshest conditions (direct sunlight, rain, hail, etc.) I have tried several other brands of LED PAR38 bulbs, but every one would fill with rain water after a short period of time. After 8 months of use (Aug-March) each bulb continues to operate and remains dry inside. The color of the light output is very similar to the halogen bulbs that I have used in the past, and somewhat brighter since the halogens were 90W. The only reason for the 4 stars is that the westward facing bulbs have begun to slightly yellow the polycarbonate lens due to sunlight. If they were used for floodlighting under the roof's eve, I'm sure this wouldn't happen.
