Deciding on LED Light for 1st Grow - Pls help a Noob!

Tent size is 3x3x6’. It’s for personal and love of the plant growing - so yields don’t worry me, looking for high quality and different strains without overwhelming amounts.

From what I read on GWE, mostly decided on HLG lights, the 300L Rspec 270w ($400) seems ideal but I have to pay for international shipping by weight so this heavy light adds +~$160, so not sure if It’s wise to spend that much ($560) on my first setup/grow.
So another idea is I could start with two HLG100 Rspec 95w because one would not be enough for 3x3. These are $150 and very light at 3.8lbs so +25 shipping each for $350 total... And later if I want these are easy to sell and upgrade to the 300L.
[Do I need a higher powered light for quality or is that more important for yield?]

Another option I like is Spider Farmer (looking at the SF-2000) but the total at ~$440 is closer to the 300L so would just go for the HLG.
Let me know your thoughts and advice. Thanks!
 
The only two square ones are 4000 and 7000 the 4000 would really light up a 3x3 it's a 450w more for a 4x4 but would definitely work in a 3x3 id have to look at the number but probably a great ppfd corner to corner with no falloff around the edges
 
Yeah I forgot about the vipar I don't know if it is still going on but Amazon had a really good sale on them
 
My opinion, if you can afford the HLG get it. They’re excellent lights and you won’t be unhappy. The other lights mentioned produce great results as well. As far as yield and quality, your light will affect both.
 
Another good light that has just come out is Sonofarmer they're a newer company but built with the same parts as the big boys with a better warranty you can find them on Amazon at a much lower price than the others using same parts built in the US and the ppfd is damn near identical which is what matters to your plants
 
I would definitely go with HLG, check out the 135w v2 rspec, puts out as much light as a 250 HPS and when dimmed down the whole way to 60 w it has as much power as a 150 hps, I use two in my 2x4 (same amount of space as yours) but if your not going to have plants wall to wall you may only need one light rather then two, in my experience just one 135w will flower 3 2ft plants in 5 gal pots. I also rotate (turning) my pots a little every day to help ensure all leaves a buds get light especially plants next to the wall of my tent

Again, regardless of who's light looks better or cheaper or whatever, as far as I know the only manufacturer who has safety certified lights are from Viparspectra and even then only a few models. Unfortunately the industry is rushing to meet demand as growing weed is now becoming legal in more places around the world so they pump out whatever light they can in order to make a buck.

For an electrical item that generates heat and is on at least 12 hours a day for several months, do you really want a light that hasn't passed government level safety standards? Look for ones that are certified UL, CSA or ETL.

Most of them are "CE" certified which is a sort of "in house" certification and is not as strict or compliant as the others. Even the CE certification is faked in a lot of cases so it's buyer beware IMHO
 
Pretty much...
I have 3 old fixtures collecting dust in the closet.
Lighting is probably the most important aspect of your indoor grow.
A 3x3 will have at least an average 750ppfd across the canopy when you have approx. 300 watts of top-bin diodes.
Most commercial led drivers will output 320 watts in that power range, so that's what I would try to use.
 
I can’t find a 135w HLG on their website or amazon, goes from the 100 (95w) to a 225w and the 300 (270w)
