this makes no sense radiant watts maybe, but as stated above not PAR watts 100 watts/SF of LED (at 50% system efficiency) is ~50 PAR watts 40 W/SF of LED is ~20 PAR watts or almost 1000 ppfd most people run 35ish W/SF of LED to get 700-900 ppfd OPs insane rig when dimmed down will be so...

thats correct. thats why i sell 48As and 54Bs but not 48Bs (voltage too low) or 54As (risk of voltage too high if too few cobs) both 48A and 54B top out at 53-54V and are relatively foolproof with the ~50V cxm22 as well as citizen 1818 and 1825

you know i dont sell fixtures, right? only components from major manufacturers with legitimate specs.

yeah opinions = worthless third party photometrics = priceless

naw only shitty ones hlg and timber are both my competitors... but i have nothing but good things to say about them. because their gear is legit, with real photometrics.

this should go well "ok i did the online documentation you asked for to get my free light" "yeah but those guys totally eviscerated the gear" "uhh.. not my problem? Make better lights next time and maybe you wont have to give them away for free?"

at least

also neither has really gotten any more efficient in that time (aside from the use of square wave ballasts that you alluded to)

best to read a bit and then start a thread. this isnt the best place for that 50 w/SF is about 50% more than you need with efficient LEDs you can do fine with one spectrum 3500k 80cri would be good

just a guess, that like many here, he is here to help his fellow grower and share useful info about what works, what doesnt, and most importantly, **why**, so people can learn and be empowered to make their own decisions

this is gold, really

samsung is a korean company that assembles most of its LED products in china

madness! i hope you can use all those photons. better stake those girls up good you'll be growing footballs

not sure about AU but in the US hydro stores mostly exist to sell stuff to people at exorbitant markup. many (if not most) look at their unit profit per fixture higher than their net benefit to the customer. As a result most are 1-3 steps behind on the current tech if i didnt use rockwool and...

some of them might have products equal to or better than QBs. but that still doesnt make them QBs. you roll the dice

not actual Quantum Boards though. you can save some money by buying knockoffs but there is no guarantee of the spec you will get

thats usually when the thread is over

familiar with their products would call that a top choice by any means

your costs arent really close to realistic you can beat a 1000W DE with $1000 off the shelf or $500 DIY

for an SE it can. DE, not quite (yet)
