What is the difference between infrared and incandescent light?

 

[Aztek]

Infrared puts out red light and heat.
Red bulbs give no heat.
Incandescent puts out all colors(white)

If you're asking the affects it has on scorpions.

Scorpions are instinctively to be afraid o white light since it basically means its daytime when predators are out. Using an incandescent would simulate this preventing your scorpion from coming out when its on.

An infrared only puts out one color(Red). Their instinct cause them to fear red since in nature red light would mean nothing really. You'll have a higher chance of seeing them out and about with infrared bulbs.

Red bulbs are the same as before except they don't give out much heat.Just for viewing.

 

[winter_in_tears]

thanks. How about incandescent red?

 

[Aztek]

Those are the red ones I mentioned that are for viewing, and don't really provide much heat.

 

[pandinus]

an infra red bulb contains gases that actully emit infra red light, a red incandescent bulb is just a regular white bulb with red-tinted glass.

Infrared are usually shaped different aswell.
Incandescent reds look like your regular old lightbulbs.

The way I understand it, infrared is a radiating wavelength like light but it is not visible with the naked eye. The heat you feel from a bulb is infrared wavelengths, the light you see is a diff wavelength of radiating energy than the infrared. You can't see it with your eyes unless you have an IR camera, which I've looked into getting but they are expensive. If I understand it right, every object gives off IR. I'm speculating and haven't read this but going by the way I understand it, I think the only thing that would not emit infrared is something that was at absolute 0. Anybody know if that's right or not, the absolute 0 thing? So I think an infrared bulb is called infrared not because of any light you see from it, but it's because of the radiating heat it produces. If I'm wrong, let me know, it's something I've been thinking about too and that's how I've been seeing it.

Just so that you all know all light produces heat.

thats about as accurate as you could hope for. everything does produce SOME infrared which is how some animals hunt. i can't think of any examples right now. but i'm sure if you ask one or two of the more "senior" members could help wit that.

Pit vipers can detect (see) infrared, and that is one method by which they hunt, some of the boidae can also do this (although not as well).

Not Chemiluminescent things, fireflies, light sticks, etc. I believe that reaction produces light without heat.

I think you have it wrong here my friend. Light = heat, but heat DOES NOT = light. So yes many snakes with Labial pits, or heat sensing pits e.g. Crotalids can sense heat, but there is no way that these pits sense light. Their eyes sense light, and that's it.

Infrared is electromagnetic radiation, light is electromagnetic radiation, infrared is below the color red and not visible to humans. Infrared is detected by the labial pits of boidae and the facial pits of many vipers. In both cases these sensory organs are wired by the trigeminal nerves to the optic lobe of the brain. Although not perceived by the eyes, this does actually render the ability to see infrared by these taxa. Furthermore these organs are situated in a manner that provide depth perception to the "image".

Human visible light does not always = heat, i.e. bioluminescence, and heat does not always = light visible to humans (light is all electromagnetic radiation, UV light for example is light even though human can’t see it).

 

[atrox]

I appreciate your point here, but the labials are still perceiving the radiation as heat and not light. These organs are not capable of perceiving light, only heat. Since light is radiation, and therefore heat the labials are doing what they should. Detecting heat...

The labials are most sensitive to radiant heat, this is heat in the form of electromagnectic waves. Here is a decent diagram of the electromagnetic spectrum...

Infra red is as much light as ultraviolet is light.

This may stem from a semantics issue, and a less than optimal understanding of electromagnetic radiation. I still stand by my statement...

"Pit vipers can detect (see) infrared, and that is one method by which they hunt, some of the boidae can also do this (although not as well)."

the term "see" is because of the fact these nerves conduct to the optic lobe of the brain, and the field of perception from each pit overlaps to allow for depth of perception.

 

[atrox]

It's been ten years since my nuclear chemistry courses (I think my understanding is reasonable), but I agree that this is a semantics issue.

 

[winter_in_tears]

you guys are awesome. thanks for all this amazing info. I had incandescent red before, but from reading all the advice here the right thing for me is to go with infrared.

Thanks again!

Just tried a 25W red party bulb the other day from Lowes for 2.38. For the money, it works for me (just for viewing).

Haha, this is such a useless appendix to the question asked, but, people are mostly right. I'm absolutely positive about everything I say here. Heat is defined as the TRANSFER of energy, which does not have to include EM radiation or light. Temperature is defined as a measure of the average kinetic energy (kinetic nrg = nrg of motion) of a system. Electromagnetic radiation, however, is simply when a photon (packet of EM radiation) is emitted from an electron going from an excited to its ground state and giving off energy in the form of a photon. infrared is produced from the gasses in the bulb, being that the energy input into the gas emits only a spectrum of light in the infrared range. In a standard filament bulb you run electrons through a highly resistant material and the only way to get rid of this energy is by A.) emitting photons of visible light, and B.) emitting photons in infrared, heat. compact fluorescents work differently and so do metal halides. regular light bulbs don't have the gas necessary to produce a great deal of infrared, only the resistant filament to produce mostly visible light.

 

[skips]

right, if you want transferable heat, you want infrared. if you want viewing, actually both work.
