at end of this intro imma paste part of a comment i posted elsewhere that basically sums up breifly my pros and cons for the lights i am choosing between. the spaces are all 3x4 closets. in the end there will be 3 of these chambers and all3 will host full cycle grows from seed to flower. i am not doiung a veg area other than mothers and clones, but that is off topic and not part of this design. anyway, i will probably end up doing 2 of each light in each closet for a total of 6 lights. reason being is i kinda want to test em all over time and in the end the differences are negligeable grow wise i think. anyway below is my pro and con list i posted before. could anyone with first hand experience add to my summary or give me what they would do given the info i provided. please tho don't just respond to tell me how awesome your mars tsw or spider farmer is. ik they are all awesome and will more than do what i want. my goal tho is 1k+ ppfd per m^2 evenly accross whole canopy in flower without doing a diy strip build. so i am looking for anyone who can specifically speak to ppfd footprints or anything else of merit not general i have x light and it rocks. that said if you got yeild results please share those but if you do please give me dimensions of canaopy number lights etc you are using

will be using 2 lights for each 3x4 space. these are all excellent choices and have positives and negatives when comapred to each other.
1. spider fqarmer uses samsung diodes and meanwell driver but its dimensions make it act more as a single bulb light source than taking advantage of mid power diodes ability to spread em accross the space. even using 2 in my 3x4 i am concerned about even ppfd. ik it will work great but i am trying to acheive close to 1k ppfd evenly not 1200 in the middle and 650 on the edges. these are also the most expensive dollar wise and also dollar per watt wise
2. the tsl and tsw series uses chines drivers and new epistar led. i am okay with the diodes tbh, the drivers concern me. this light's longevity and failure rate would be my concern here. also concerning is the lack of coating on led's making it not water resistent at all. that said these are the best bang for the buck if they last because you get 300+ true watts for $249 including shipping and tax. two of these is cheaper than the parts to make a diy strip build of 600+ watts with either bridgelux gen 2 or samsung diodes strips, which to me is a great thing. what i cannot decide here tho is the tsl or tsw. 2 of either covers very similarly. i wish i could use a par meter and test them both in my space to decide.
3. the sp250 is lower power than the tsw and tsl but uses the same meanwell 240 as the spider farmer while sticking to the newest epistars for the diodes, which again i am fine with, but i wish they would release the diode part number so i can comapre data sheetes with bridgelux and samsung but when you look closely using other metrics to figure this out it seems to be on par with the lm301b and gen 2 bridgelux. this light has the best build qualiy and runs cooler than all the others. it is also waterproof basically with a ip65 rating. my actual only hesitation here is the lower wattage compared to the tsw and tsl. the ts series wouild give me more par simply because of more watts. i'd need to keep this sp250 at like 12" to acheive 900+ppfd m^ per light which is fine but i can get like 1500 ppfd m^2 in center if i wanted to try and lower the ts series that low.
**in conclusion my main concern with either spider farmer or the mars sp250 is i feel like i ultimate would need 3 in my space to acheive even spread at a high 1k+ ppfd m^2 mainly because of the 12" height they need to be at reduices the footprint below 2x4, again if you want even like me. clearly 2 is more than enough, but i want uniformity whoch is why i was gonna diy strips. but the prices of these lights above make me not want to bother diy if i can come close for only $500(for 2) already to go. i am leaning sp250 or tsl2000 if im honest tho and am mostly hung up on do i want to spend the same money for less par to get the meanwell driver and ip65 rating and cooler more efficient light. in reality 3 sp250's is ideal but then we are talking $750 not $500 for each 3x4 space. that said i would start with two and buy a third eventually and see if my yeild goes up. if not ill use the third in another closet for veg or buy a 4th and make that 3x4 another flower chamber
