It's been a long day
I guess that answers a lot of questions. Thanks.
The umol/sec/m^2 factor hasn't been relevant to me before but I'd like to learn more about it. Any directions to past threads explaining it would be greatly appreciated, comrades!Total Max. Soft On Set time period : 27 min.
Minimum Plug Power Diss. : ~50 W ( @ Stabil.Oper. )
...After four presets* in between :
Maximum Plug Power Diss. : ~270 W ( @ Stabil. Oper. )
~1500 umol/sec/m^2 ,center beam, @ 20" from canopy ,
270 W plug pwr ,@ stable operation,Ta= 23°C

Preset : - Growth Phase :
1 - Clones / Mother plants / Flowering males for pollen collection ( ~50 W )
2 - Seedlings to third-fourth pair of real leaves . ( ~75 W )
3 - Young plants ( ~ 100 W )
4 - Late veg / Early flowering ( ~150 W )
5 - Early / Mid flowering (~ 200 W )
6 - Mid / Late flowering (270 W )
Cheers.

This can get you started. Ms. Cannabis is only concerned with the density of what you are packing. And she wants as much of that per second as you can give her without harm.The umol/sec/m^2 factor hasn't been relevant to me before but I'd like to learn more about it.

To get more precise results you can use specific numbers calculated for each source. All you need is LER (in lm/W) and "quantum efficiency??" (number of photons produced per energy dissipated - umol/J).This can get you started. Ms. Cannabis is only concerned with the density of what you are packing. And she wants as much of that per second as you can give her without harm.

Micromole:
per second and square meter (μmol m-2 s-1). This term is based on the number of photons in a certain waveband incident per unit time (s) on a unit area (m2) divided by the Avogadro constant (6.022 x 1023 mol-1). It is used commonly to describe PAR in the 400-700 nm waveband.
When it comes to that stage, Sailor, please elaborate on the painting process.On the process of a new built ..
2x Vero 29 ( Ver. 1,2 ) @ 350- 2200 mA range with "SoftOnSet" for the one of the two COB arrays.
Future owner want its to be a "classy" design ...
Vanilla Cream White ,painted also ..
Well .." classy " ...
Time to use some ..metal-core-printed-circuit- board ( aka Insulated Metal Substrate ) ,
left-overs from the Oslon era ...!!!
To make a nice " label " ,for starters...

A copper plated aluminium label ....
....
Fits awesomely with the black bakelite knob ,don't you think so ?
Classy,enough ,I 'd say ...
Cheers.
Well,someday I will finish it ...
Changing my mind lots ,regarding this light ...
Apart from the "Soft On-Set " feature it will also have a led blinking ,
showing that the fan is operating fine .
The small circuit used blinks a led ,with the frequency depending directly at the fan's speed .
It uses the "TACH " wire of 3 or and/or 4 wire fans .
( Blink frequency = Fan RPM * 2 / 10 ).
So ,if a fan of 1200 rpm is being used ,then the led should blink 4 times per second.
If the led blinks with a rate of one blink per second ,fan's speed has dropped to 600 rpm for some reason.
If it stays OFF or On ,the fan has failed and no longer operates.
So .. A blue small led ,for the "Fan OK " thing and a bi-colored ,red-green ,for the "SoftOnSet " thingy ...
I the mid ,the 12 position ,single pole rotary switch ,with SMD resistors ,adjusting
the driver's output current .Min positiopn is at " I " ,maximum output is set at position " XII "...

Have to wait for the transparent varnish coat to completely dry,before handling ...
Steam-punkish classic copper details ..

So you've become bored with making COB fixtures and are now working on building time machines.. how did I not see this coming?Well,someday I will finish it ...

Nothing to do with time or "orientation" this ...time ....

Yes,I've tro agree ...Quite far and away from ufos...
Leds are worthy devices its nice to see someone take the time they deserve....
