Heck I was away for more then 3 months this summer and when I was catching up with reading I realized that lively debate and exchange of ideas continued. And that's what these forums should be abt. BTW even without a good Mod like Stinky around some of us really can keep it civil. (but with me that's subject to change w/o notice)

just report bad posting by clicking on the "report post' triangle (at the top, right of every post)
...P4B or IAP will suck it up like a vaccum cleaner...:thumbsup: ..don't attack, only defend...:stoned:

Did you try the "transition" eyewear test or are you just guessing? Whitchever, look forward to seeing your results, your always welcome on my porch.

I can't find the damn things...I think their in King Tut's Tomb...:detective1:

Is this what you're looking for?

Actually, no.

Says he can't find his "transitions" eyewear to check for UV.

What the "report post" comment is about escapes me though.
OM encourages sidetalk, yah?

Mus' be da side effects.

Weeze

Hey HMR,
Always good to sse ya. I think DP was referring to that, but he knows where it is and was pointing out to me to use that rather then going on the offense.

Yo Dutch,
I've have used that rather then engage some of the real idiots but I think I might go medival on someone soon. Got my eye on a huckster, I left a snarky comment to but think I need to take him down a peg or two.

Oh Weezard,
I do encourage side chatter and do go OT some but it's probably just my distain for the rules, heck any rules anywhere.
BTW very nice test equipment, haven't see one of those sun spinners in a long time.

To Rusty, knna, weez, ET AL,

This is almost OT; I keep notes on small index cards when I look at things on the net or I'm reading. I just came across a card with some notes on it, not sure where or who I copied it from, heck not even sure what it all means but:

Bright Sunlight Provides Irradiance = to 1KW. Brakes down to:
527 watts of IR
445 watts of Visible light
32 watts of UV (longer wave, lower frequency)

I assume I was trying to figure how to mimick daylight indoors, but it is something to think about.

I have always assumed that 1000 watt HID is the perfect grow light..all things considered...

and adjust my duel 400 watt lights; accordingly.

"527 watts of IR
445 watts of Visible light
32 watts of UV (longer wave, lower frequency)"

Ah, that's what I based my solar insolation specification from for my lighting!

Hey Khyber,

Did you post that somewhere?
What is "insolation"?
And how do you achieve 527w of IR?

KwH per M2 per day. I think.
The solar power folks use it.
The average insolation of Honolulu is 6.02

Down by us it's a bit higher.:cool:

Aloha, Weeze

"And how do you achieve 527w of IR?"

Start with a 1Kw radiant room heater?:D

No, I didn't post that, but that's what I started basing theories upon - known data.

Since I'm only targeting VIS for right now, IR and UV become irrelevant for al other measurements and emulative attempts.

I count quanta instead of watts, so I have to do a conversion to get PAR quanta counts across each targeted wavelength.

Insolation is the measure of solar irradiation at two points - the edge of our atmosphere, and at sea level, as measured without any other disturbances such as clouds, just the regular atmosphere.
