please help with LED information - have looked at Kind Led’s (expensive) but the Virspsecture (misspelled) looks great for $200.00 . really confused ??? need help to find a quality led but in the price range of 100.00 to 500.00. This is a great site and I’m sure I will get some very good information

What size grow room are you working with @steve2?
I don’t know much about LEDs but I know the size of your grow room will be needed in order to get you set up correctly.

Hi Steve, we can probably help a little more if you tell us what size room you’re growing in.
I’m assuming you are growing from start to finish under the same light? If not, please let us know.

I have the Viparspectra 600W and I love it!
They have it on sale on Amazon right now for 161… normally in there for 179!
Would be great for 1-2 plants in a 3x3 or smaller.

I vouch for meizhi as that’s what I use and granted this is my first grow they seem to make my plants happy. I have the meizhi 1200w, 600w, and a 300w on the way all with veg and bloom switch. I contemplated between vipraspectra, mars hydro, and meizhi. From what I hear all these are tried and true and have good results from plenty people on this site

here is what I’m leaning toward- Viparsctra - Par450 - 450 led grow - 3 dimmimabel - 12 band - cost 189.00 . wold like a Kind but to expensive right now. looking at 2 - 4 plants grow. Viparspectra seem to be a good low cost led. thoughts ? thanks

will look at the “Meizhi” led’s - thanks !!
Yes - start to finish ! have a 3 by 3 grow space . Black Dog is rated in the top 5 led on the market but to expensive seem good for commerical use
what about side lighting - using cfls’ ? looking at led strips (Kind led $129.00) expensive. that wouldn’t influence PAR?
What size tent are you in?
If thats going to be your only light I would lean towards the 600W for the wattage. You’ll want as many true Watts per sq/ft as possible.
The 450W par 450 is great but has 210 true Watts where the 600 is pulling 270! And the 600 is cheaper right now.
Just my thoughts!

have 2 other rooms - but want an led for a 2.5 feet wide and 3.5 feet long ) small space I know strange size) was considering the Kind K3 L450 great light sells for 850.00 but can get it for 600.00 - bit expensive. have looked at so many led’s make my head spin !!! looked at the one’s you guys mentioned (Meizhi) now leaning on the Viarspectra 450 dimmimable (189.00). still confused ??? Help the 600 is the reflector type ? reflector what dp they mean
Once again I’m new at growing indoors
But I spent a lot of time researching indoor grows especially lighting before I made a choice
I was given a like new twin 600 watt hid setup by a friend who was up grading to twin 1000 watt led’s.
I thought I was off to the races. Then I researched it and found it would work but just not enough for my needs.
I’ve learned that how much wattage a given draws from the outlet does not really correspond to the lumins and par it produces. Or the heat it gives off.
For me LEDs made much more sense. Once you factor in life of the light and cost of electricity used the extra cost of LEDs equals out. To say nothing about the cost and hassle involved to vent the heat away from HIDs.

I’m not sure what they mean by reflector series. It might have to do with how the leds are reflected? I know that it does have 2 switches- 1 for Veg and 1 for bloom and it says it’s good for a 3x3 room.
Your room is 8.75 sq ft and the recommendation for LEDs is to be 35-50 true Watts per sq foot. The 600 would be 31 watts/ sq foot so that would get you pretty close.
Hope this helps.

You want an led that hits the peaks of McCree curve in red and blue, and to pay attention to the actual watts consumed by the light. Manufacturers can associate any number they want with the light, but watts consumed in the correct spectrum will dictate your ability to maximize each stage of plant growth.
They will all grow. You have to find the features that fit your grow and budget the best.

@steve2 here is the spectrum produced from the light you linked vs the kind k3 450. To translate the difference in usable terms… both lights look to be excellent for veg stage. While the kind will excel during flowering and ripening stage.

great information and thanks the viparspectura seem’s great for the price ans adddtional “watts” but it isn’t dimimable is it like the 450 - it’s a bit cheaper than the 450 thanks

I’m not really familiar with the options available on the Amazon lights, but I thought vipar offered dimmable and non dimmable versions of most of their lights?
Personally, if the light has a switch to add/remove the red you should be plenty good. Several growers here are successful with the 300 models that offer neither. Being able to remove red for veg and cut down on some stretch is just an added benefit. It’s nice to be able to dim them when you’re in the room, but not necessary. A set of glasses is recommended either way. And let’s face it, you don’t really want to be stealing your plants light anyway.
