Download the photone app off the playstore and you can make sure you don't exceed the recommended ppfd for the stage your plants are at .is there such a thing as in to much light? by adding another full spectrum light.
useing a philizon 600w = to 350 watts i believe. full spectrum.
Don't you mean TOO much?to much
There are 2 different wattages one is the wattage a led fitting draws and the wattage the fitting outputs they won't be the same on a LED fitting .
This is why LED'S are used for light fittings in households because they are cheaper and more economical to run for the output of light so comparing consumption wattage with output wattage doesn't really work
Led lights output more light than incandescent filament lights because they are more efficient therefore the actual output wattage is greater than the consumption wattage.you can't output more than you draw. it's not possible. physics.
this is where everyone gets confused about led, and where cheesey mfgrs create the space to rip folks off.
there are two ways they do this.
the wattage a led puts out is not greater than what it draws. the amount of lumens, or par, or ppfd, a led can develop is greater than what a hid can manage consuming the exact same amount of energy. the difference between the two is the amount lost to heat.
bad builders use the difference to claim the actual wattage output is greater than the input. it is not.
the second way they do this is related to how a led emitter is powered.
led emitters are never powered to full capacity as a safety factor. even when fully powered a led emitter is never really driven past 50% of its capacity. bad mfgrs also use this space to claim the light is capable of reaching outputs greater than the inputs, when in fact it is never used.
honest mfgrs only make wattage claims based on what the driver consumes at capacity, which should be the same as actual draw from the wall. that's why led growers always talk about actual draw or wall draw. that's a far more true comparison.
the only meaningful measure of wattage on a light is only what the driver can manage. if it consumes 100w, it is a 100w light.
bottom line : what you are looking for is the amount of ppfd that can be created for the exact same watts consumed between any two lights.
The output is not measured in wattage. It is measured in lumens and the LED bulbs produce the 'equivelant' amount of lumens as an old style incandescent bulb but use fewer watts.Led lights output more light than candescent filament lights because they are more efficient therefore the actual output wattage is greater than the consumption wattage
Led lights output more light than incandescent filament lights because they are more efficient therefore the actual output wattage is greater than the consumption wattage.
I get what you are saying about manufacturers but they aren't all the same
Then one day the last remaining bit of energy & matter will finally be sucked into the only black hole left. And a trillionth of a second later it will explode and produce the next big bang and we start over.you can't output more than you draw. it's not possible. physics.

Correct, that is partially my point to say a 100w incandescent globe is putting out the same performance for the wattage just isn't true you get more light for your buck with LED'S or we wouldn't be saving money on our electricity bills by fitting LED lighting in our houses.the true measure is the amount of ppfd for energy consumed.
I understand physics but it comes down to efficiency LED lights are 30 - 40% more efficient
True but they use that energy more efficiently giving you more luminanceyes, but they don't create energy. using wattage as a measure is misleading.
True but they use that energy more efficiently giving you more luminance
True, but its the result we are after how much luminance and the point i was trying to make is per wattage the luminance from LED is more efficient therefore better bang for your buck than incandescent lighting
So working things out by wattage to get the best luminance is a little inaccurate
