What Is The Wave Length Of A Red Brooder Lamp?

[jzeno]

I own 2 red lights:

1. An LED one 660 nm 12w (low heat)(https://www.amazon.com/gp/product/B01H2Y5U4M/ref=oh_aui_search_asin_title?ie=UTF8&psc=1), and
2. A 250 W (very high heat) red brooder lamp (https://www.walmart.com/ip/Rite-Far...ed-Red-Brooder-Heat-Lamp-Light-Bulb/457015013)

I can't seem to find out where these red brooder incandescents fall in terms of nanometer wavelengths. Does anyone have a reference?

The reason for my asking is, I actually enjoy the simple brooder lamp more because it emits so much heat and it's red. The heat is actually really nice for cold hands, feet, etc.

Do you know what wavelength these brooder lamps emit?

Thanks in advance

Found the answer: The bulb has the word Infrared stamped on it, meaning it falls somewhere within the infrared spectrum.

Also found out from this Danny Roddy video that Ray Peat recommends the 250-500 W brooder lamps, too: @ 0:29

This source that Danny cites also states that while the LED bulbs are more focused in a specific range, the brooders also have some light within the 'red light' range, it's just a lower amount: http://bit.ly/1P2l16d. So, also effective, maybe just less so in the realm of red light therapy--but still good.

I like this infrared brooder lamps more because they are so warm. The LED ones are more focused on a specific wavelength, but they generate much less heat.
