can a lighting person explain how to figure out which is good and bad i have no clue…also could they take a look at this (which is my main light and tell me what it is actually putting out and if its good bad or ahhh middle
this is my current light : [Bloom Plus LED Grow Light BP1000 Sunlike Full Spectrum Led Growing Light for Indoor Plants 2x2 ft Led Grow Lamp High Output Plant Growing Lights for Hydroponic Indoor Seeding Veg and Flower Greenhouse](https://www.amazon.com/gp/product/B082Y1PMWF/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1
o.k so really need a lighting person to weigh in here. i am looking at these led cob lights here is some info so are these good? and will they yield big results? 2’x4’ REAL coverage.
38" x 4" and < 8lbs.
Gen4 fixture: 280watts. (264w (66w per led x 4)+ 16w for fans)
or do i get this?
260W LED V2 RSPEC BOARD XL KIT
260 Watt Lamp Kit. High Efficiency QB288 V2 Rspec. Suited for main light and supplement lighting. 3 ft long heatsink for a wider spread. New updated XLG driver allows full range dimming with included potentiometer.
which of the 2 will give me big buds ,big yield and be good all around from seed to end flower? please all weigh in as it will be my next purchase and hopefully last for ahile
I think @Covertgrower uses Cobs , I’m a big Hlg fan ,but that Cob light looks pretty good …let’s wait for someone with first hand experience with these
I do have cobs, but I wouldn’t look at a fixture with fans. My COB’s have no fans and dissipate heat passively.
Not saying they don’t work, but I would want to know what led they used.
It is time to do some reading… And I don’t mean a couple hours worth. It’s one of your biggest investments and by far the most important factor with growing. I started 2 years ago indoor and I’m still lost. I built mine as well but it’ll make your head spin. Good luck and nice meeting you.
I solely use HLG quantum boards and have never looked back. I have 16 total and can usually get upto 4oz per plant in 3 gal pots. After about 8 weeks veg.
just so you all know I am more than happy to learn and read. but all the reading in the world can not substitute for actual gained knowledge from using/experimenting. I read as much as I can about all the subjects but its like I’m reading another language especially when it comes to lighting. the different types the actual wattage coming out of wall and of course every site claims their light is the best. its extremely confusing ohms and symbols arghhhhhh… so this is why I’m asking maybe there is a lighting for dummies…lolol I’m not trying to be an idiot but something that breaks down what it all means. I don’t have a huge budget but I want to ensure the next time I lay out 2-3-4-500 bucks for something I’m getting what I need to do the right job. This is why I asked for opinions. Not to short cut but to get as much info as I can to make a good informed decision. I know this is a learning process and we all put in our time just sometimes some of us need help in math or science but we are good at other classes so please don’t take my asking for short cutting I’m just trying to learn from the best!! You all here who have been so great and explain things so us newbies can get with the program. I am grateful for all your input and truly appreciate each and every one of you. Happy growing all
Light you have looks about 90 watts. I wouldn’t expect it to run any higher than 1.5-2.0 umol joule, if that.
The cob fixture you posted would need model number of cobs and driver on. If you have that i should be able to tell you just about all of the performance specs. I agree that you would be better off with passively cooled pin sinks if you go with cobs, no fan to fail and less power consumed. But pin sibks will be more expensive.
@dbrn32 ok so maker sent me this info today"about 280w 2.4amp draw dimming on driver chips are arranges 3500,4000 3500,4000 " and this is all he says he grew these on them
@borialis I will check it out soon I’m just trying to get the right lights i keep tossing money at this and it seems I’m making wrong decisions so this time i am going to be sure what i get will be absolutely the right one!!
@NeoGroR ya I am looking at 1 of them now also but this cobb light is $280 which is like 90 bucks cheaper than the hlg light i was looking at. its hard when you are new to something especially when all the jargon is thrown around to figure out what it all means so this is why I am asking i have tried googling info on this stuff but i just end up getting more confused so hopefully with all weighing in i can find the 1 light and wont have to keep throwing away $$$$$ I am attempting to buy in the middle of next month but may have to wait till i get all the info…tired of throwing away $$$$ on bad choices
@NeoGroRso i am looking at either the cobb above or this hlg : 260W LED V2 RSPEC BOARD XL KIT
260 Watt Lamp Kit. High Efficiency QB288 V2 Rspec. Suited for main light and supplement lighting. 3 ft long heatsink for a wider spread. New updated XLG driver allows full range dimming with included potentiometer.
any thoughts here?? let me know
@NeoGroR so as of right now i have a 36x20x63 grow tent. would these work there and what about heat would they be ok there? and would they work from seed to flower all the way thru??
@NeoGroR and B.T.W nice buds…see this is what im looking for my #1 girl had all kinds of issues and i just harvested she netted me 1 oz
need something that will get the job done and done right!
One 260 kit would do the job. It’s good from seed to harvest. You’ll get buds like the pictures.
The harvested buds in the pictures netted me 7.25 ounces dried. And I was learning the whole time. A little bit of knowledge and having one grow under my belt is giving me the full tent you see there. I’m hoping for a pound. I’ll be happy with whatever.
They’re really easy to put together. You can find some YouTube videos on it. If you need any help, tag me.
In fact if you wanted to save some money, you buy the heatsink and boards for $185, then the driver separately for $60ish dollars. And then make a $25 trip to the hardware store to save you some money.
so please don’t take my asking for short cutting I’m just trying to learn from the best!! You all here who have been so great and explain things so us newbies can get with the program. I am grateful for all your input and truly appreciate each and every one of you. Happy growing all 
so this time i am going to be sure what i get will be absolutely the right one!!
so hopefully with all weighing in i can find the 1 light and wont have to keep throwing away $$$$$ I am attempting to buy in the middle of next month but may have to wait till i get all the info…tired of throwing away $$$$ on bad choices
