Hi Ttystikk - good to see you alive in the current climate conditions.
The weather in your home country is very dependent on the Pacific Decadal Oscillation (PDO).

Right now, (in a La Nina phase) you should actually have wetter and cooler conditions...
Your driver works with a 3 in 1 dimming function ( 1~10VDC, 10V PWM signal and resistance )

I assume that you will find a black rubber nipple on the back of the driver. Remove it - now you can use a slim +screwdriver to adjust the...
i use a heatexchanger to put the heat in - and pump it to my shower to release
in hot summer (when i do not grow in my flat) i use the same combination of heatexchanger & led lamp to keep my apartment cool.
Filling the heatexchanger with fresh service water (15°C) in the morning. I use my led...
i was born the day when JFK became president - my name is not Lee Harvey Oswald o_O
and as an artist i`m old enough to use any context to punish the biggest mother-earth-fucker to death - once my personel judgement is finished.
While Hitler survived several attacks from different assassins...
small is good - but a solid, well insulated chamber with a reduced min. airflow will help you to keep higher temps.
real 300W led-light still means ~225W (~75%) of produced heat + ~75W(~25%) light, which then is converted to heat on the surface of the inlighted area, if it doesn`t serve for...
I`m glad to have built a watercooled led light -
with summer outside temps. close to 38°C (100°F) most of indoor growers have problems with too much heat.
If then you are able to transport a big part of the produced heat to the outside of the grow room
without additional electricity - you...
:peace:

Your driver delivers 14,3A - so each of your 16 leds will receive ~ 890mA - that`s too much.
Buy more chips and understand, that driving your leds @ low current increase
light efficiency and...
as i like it simple - i would wire 3 conventional ( ~ 300Wp each ) pv modules in a row.
you will receive a voltage ~ 85-125V and a max. of 10A ( depend of temp. and sun radiation).
so you could run 8 qb (Vf 45-58V / 3,2A) 2 qb in series and 4 in parallel.
no converter - no driver needed to...
plastic and expoxy is janky !
a screwed flange with a rubber sealing is the professional way to close a tube in pipeline constructions.
the lamp fixture in above pic ^ is a worldrecord holder in energy efficiency, because it is watercooled
and can rewin 60% of the inverted electrical power as...
