Did you check the dimming function ?

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). https://www.pmel.noaa.gov/elnino/lanina-faq 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 ) https://www.meanwell.com/Upload/PDF/HLG-240H/HLG-240H-SPEC.PDF 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: https://www.tme.eu/de/Document/970b20b9b9d0b2c2e983c9ab269f5702/HLG-600H-SPEC.PDF 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...

yes -

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...

have you ever heard about curtains ?

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...

no plastic - no expoxy i use aluminium and rubber to close the tube -

aluminium square tubes - closed with flanges is cheapest and best...

the harder you try to take a pic... --- here again is what i expect to find in your cirrus light comparing shit vs. shit

please take some pics of the cobs

slowly cooked apes

:peace: --- too much silence - toooo slow i know it`s arrogant to claim oneself a "worldchampion". on the other side: everybody could use the above design with better (more efficient) chips and drivers and claim this title for him (her). (:

:peace: yeah brother just do it today i will finish mine - 105 x 55cm / "wireless soldered !" 7 band spec. / 500W for 1,5m² / ~ € 300,- as a recommendation !!! don`t chill the water with add. electricity --- try to use the produced hot water in (shower, kitchen, washing mashine...
