Question: Does the ambient temperature (e.g. 0 degrees Farenheit) affect turn-on and/or brightness?
Document: Excellent led flood light bulb very bright and works well even at 10 below 0  the bulb came on at full brightness not like Florencents bulbs that have to warm up to get max lumens out of them
This bulb is not &#34;instant on&#34;, as I have it next to a halogen PAR38 in the same fixture, and this bulb lags behind the halogen by ~.25 second when turning on. Not a big deal, and of course it comes on at full brightness, and if it weren't next to a halogen I never would have noticed the delay.Color temperature is cooler than halogen, but still very much in the warm range.
This was my third purchase of a pair of these outdoor floodlights. I have been slowly waiting for the incandescent floodlights to burn out so I can replace them with these LED lamps. The brightness is the same and the color temperature seems crisper. Now I shouldn't have to get on the extension ladder to replace floodlights for several more years. Another bonus is that all six of these new LED floodlights together burn the equivalent of one of the previous incandescent floodlights, now that is a savings!
i bought 4 led outdoor flood lights for which will last 10000 hours which in turn will save me money in the long run
My others were supposedly the same rated brightness (or more so), but these have them beat by a mile allowing me to see better and further around the yard. Thirdly, the color is good. Although the color is whiter than the traditional mellow color of an incandescent bulb, it is not the harsh operating room white many LED lights produce.
Okay, I just installed the lights in front and back of the house, so I can't say how long these lights last, but they are paired with compact fluorescent floodlights of similar brightness ratings. There is no question that the LED lights are much brighter, they come on bright instantly, not requiring a warm-up period to reach their brightness. They seem well built, but time will tell for that.
This item came very quickly and was packaged very well. The bulb is much heavier than I was expecting, likely due to the housing serving as a heat sink for the LED emitter's. the blub is a true PAR38 shaped bulb which is very good. The bulb was installed and then tested as soon as it got dark. comparing it to the CFL floods I was replacing this bulb is twice the brightness and throws light about three times as far.
This lamp throws a very even light over a fairly broad area. The color is not quite as warm as an incandescent but is still pleasing. The light turns on about a quarter second after switched on and then is at full brightness. As others have noted, the bulb has slightly more flare near the base than a standard PAR38, so it won't fit some outside fixtures. I was able to get it to fit by popping out the metal retaining ring that holds the rubber gasket in the fixture.
I bought two of these bulbs for outdoor use because I was tired of the slow start up of the CFL bulbs I was using, especially in cold weather. I would usually have to wait several minutes after turning them on before I could even see my porch when it started getting cold in the Fall.These bulbs are much brighter than the CFLs they replaced, and they are at full brightness instantly - even in extreme cold weather.
Great LEDs. Picked them after careful review and they work well with my RAB Lighting STL360H Super Stealth 360 Sensor with Twin Precision Die Cast H101 Deluxe Shielded Bell Floods, 360 Degrees View Detection, 1000W Power.
