Facinating Lighting Theory... PLMK What You Think

[WeedIsForMe]

I have a 430 watt sun agro light it has an enhanced spectrum (30% more blue) it fits on a standard 400 watt ballast,I don't know if this is what your talking bout

this is what I was looking into...there was another one that literally had another filament in the tip but i cant find it...if i do ill post it up.

That is a cool light, not literally though...

Somewhat the same,Hortilux also has a bulb called a The EYE Super HPS This is the one I have also.

"The Hortilux Super HPS 1000 Watt grow bulb are the gold standard of the indoor gardening community. The Super HPS lamp has been fine tuned to provide more energy to your plants. This bulb has been tweaked to give you 25% more energy in the blue and violet spectrums over the standard high pressure sodium bulb. Since there is more blue, many gardeners use this bulb for both vegetative and bloom stages with out sacrificing final yields. The Hortilux Super HPS bulb line are environmentally friendly and contain no heavy metals."

Anyone using the cool tube? how are they on heat?

Cool tube is not a light but a type of in-closed tube like reflector which attaches to ducting that is hooked up to some type of ventilation fan that either extracts or pushes cool air pass the light reducing heat.I use an air-cooled hood which is designed for the same purpose myself.They are great for reducing heat.

100 2600 lumen bulbs isn't just gonna give you 2600 lumens.... I'm sorry...

It may not stack as in double completely.. But if the light beams cross each other, don't tell me there's not more lumens in that spot.. I didn't know we have light experts here at riu...

And the distance from the bulbs at where the beams cross will determine the intensity... Or the lumens stacking.. Once again.. Sure they don't double or add exactly.. Your not rocking 260,000 lumens... And the cfl intensity isn't really high enough to get them close enough to add effectivly...

Sure 2 400's cover more since there is 2 light sources and you can put them apart from each other.... But if you put them inch's away under one hood.. The lumens will add where the beams cross.. Especially really close to the bulbs.. And in the middle of them.. I bet it's real close to stacking...

If someone wants to test this with a light meter and some lights they have.. I'd be glad to be proved wrong..

;o)

are you going to test it???

I'm sure i'm not the only one who wants to know...

lumens dont add up yo 2600 the wholle way im using 1 150 watt EQ CFL and its retarded 2600 is enough for one plant if u got other lights on the side, Good luck

 

[fdd2blk]

two 400's will cover twice the area.
one 800 will give you twice the lumens.

are you going to test it???

I'm sure i'm not the only one who wants to know...

i already have. years ago.

Has anyone ever tested this out?

This is true if you set the lights to cross they will give more lumas in that spot. problem with cfl's is you need to have them inches off the plant and can't put them close enough to each other and the plant to gain much extra lumas.
