There are a number of boxes that will light up. What do they represent, specifically? Is it a temperature range? 60-66 degrees?

The fermometer will light up with either 2 colored boxes(green & brown I think) or three. If it's only 2 colors, then the temp is between the even numbers, ie if 66 & 68 are colored, then the temp is 67. If there are three colors(blue,green,brown, I think) then the temp is the middle color. For example if 66, 68, & 70 are colored, then the temp is 68 degrees. This works much like that of a mood ring, it's extremely easy to read once you see it in action. Since it is only labeled in even numbers, the color code is necessary. Good luck with your brewing, you can't find a better way to keep your temps:)

Typically it means that they temperature is fluctuating up/down. I have seen two boxes display color at once as it was raising temperature (today actually) but not seen more than two. In that scenario I would think that there may be a warmer spot on your carboy - possibly from touching the strip?

The white temp is going to be a colder white in the high K's, maybe about 6000, but these multicolored floods (even the high wattage) are not really designed to produce adequate white light for a room or patio, etc. They are designed primarily for their color effect. Hope this maybe helpful.

Wow. I really can't answer that sorry.... I've used it around 40 degrees but the shipper might be able to answer that. Its bright. Real easy to see in the daytime

I have not measured the temperature after the light being continuously on for a long time, but there is a plastic shroud over the electrical terminals. If the light gets too hot it will melt the shroud. I hope that will not happen.

Mine is mounted under plastic shelving, I have had no problems. I have it connected with an adjustable rope through eyelets attached to the bottom of one of the shelves, so I can adjust the height based on plant height. For more precise info, I turned my light on about 15 minutes ago (not growing anything just now), and checked the temp with an infrared thermometer. The top of the housing is 67 F in a 60 F room. The hottest temp I can find is 121 F. That is shooting directly at the bulb. I can only barely feel warmth at 1/2 inch distance. Obviously in a small enclosed space, in a warmer room, you would get a little more heat. But nothing capable of melting sturdy plastic. Mine is mounted under plastic shelving, I have had no problems.

I installed two of these on one of our forklift. I talked to the driver on your question he believes one of the lights would cover 60 degrees. He also said he really likes these flood lights since they flood the area that he is working in and truck drivers coming into the yard spot him right away. Hope this helps.

The color temp of the light is approximately 3000k so on the warmer side. Comparable to a Halogen light.

Not sure Of the light temperature but they are very white. And super bright I purchased a double row 20" light bar and ended up keeping the single row.

Just to give an idea of what your asking, 4000 K is 6740 degrees F. So yea, I would say any lights you find will not get that hot considering it will kill you, your neighbors and more. Not sure where you pulled 4000 K from.

I would say it would be around 90 degrees. I am using them in my outdoor flood lights and they seem to work well.

It is near 0 degrees here today, plus several feet snow. Needless to say, I won't be measuring box. I will say it is larger that ordinary metal mailboxes..holds large bundles mail, plus small packages. Also has paper slot beneath. Hope this is somewhat helpful!!

I can't give a precise response...but I can say that the amount of heat is not very high at all. If you are using them as growing lights in a cool space (as I am), heat pads are the ticket to provide an increased soil temperature.

The light temp is 3000K which is in the warm white spectrum, maybe a tad bit cooler than 2700K. We use these as accent flood lights on our house and the color is very nice and bright. They are not cool white.

Well,the heat has nothing to do with the degrees of the output angle of the light.I think you have the degrees mixed up with heat .30 degree led is like a spot light, the 60 is a flood light.hope this helps

Good question; maybe would be clearer if you asked "color" temperature. I would expect about 5000K otherwise people would be complaining about blue garbage light.

Ii ordered what was available and don't know if these come in higher temperature ranges. For the price they supplied a nice glow to a dark area.

I don't know but it has performed beautifully through a Charlotte, NC winter, where the average low temperature in January is 30 degrees. We installed 4 of these lights in front of our 56,000 square foot, three story office building and they have exceeded expectations on every level. We hesitated to install them due to their low price, but could not be more pleased thus far.
