Understanding the light spectrum please help

[Ganja_Man2k5]

Hey ya'll I'm just wondering exactly how the light spectrum works to a degree. I know all the basics as far as what lights to use and when. I also realize what colors on the scale it gives off kelvin temp wise. For an example 2200k is more on the red side of the spectrum ect. What puzzles me is some light bulbs that say full spectrum are rated at 6500k. Now 6500k is on the blue side of the spectrum, so my question is how in the world is it full spectrum if 6500k is a blue spectrum temp. Full spectrum in my eyes would seem to be like a range from 2200-8000k. I know it goes higher and lower than what I gave, but I'm giving just an example of a range. Can someone please tell me how in the world 6500k is full spectrum light when in reality 6500k is not, it is on the blue end of the scale.

Thanks

And good oh karma to everyone q)

It's worded a bit funky...but from what I got out of that

A full specturm bulb covers them all...6500k is the peak specturm the bulb can display along with everything else.

It has to do with the wire used and the coating applied to the glass. Past that you have different gases but I guess you're talking about a flourescent or classic

I'm not sure how it's worded funky, but thanks for the reply. If that's the case, why don't they say full spectrum 1-6500k instead of just 6500k. The bulbs I see never say up to 6500k. It ususally just says with a K temp of 6500k. I'm not saying you are wrong and I do appreciate the info as this is what I thought to. So lets say a standard HPS bulb rated for 2200K would this be up to 2200K, or is that actually the spectrum it's going to put out period. I always thought if a bulb is rated at something that is what it is rated at. I guess full spectrum bulbs are in a range then, and standard ratings of K is what it will put out period with out the range correct? Thanks again

It's probably a factor of simplicity or just how the scale is read by people in the field.

Most average people just go by 'cold' and 'warm' ..they leave the rest up to the lighting people. lol
