LED lights

I dont think its that critical.. After you do research you'll find that all are basically the same it comes down to cost. Efficiency.. Duration... After time they all loose some light intensity.. But a full spectrum seed to harvest i would recommend a viparspectra. Or marshydro i have both and they're excellent..cheap on electric bill..easy to install.. Service center are great might take some time to get back to u but they are both huge companys............it's like a bike race.. On paper 1 wins by 0.0002 of a second in real world that cant be measured... Same thing the difference in 1 or the other aspect cancelled the difference so for me it came down to cost which 1 i could afford.. But for most part any led full spectrum over 1000 watt is great they dont pull 1000 watt of electricity my 1000 pulls like 240 real watts... Good luck on your choice...Have fun Stay safe Growers❤️💯💯

to many variables for "best" Migro on YouTube does a lot of light reviews, watch some of his stuff and make notes of what you think you want. U got three main LEDS now, single like a COB, quantum boards and Strips. I use a lesser brand and am Quite happy with them. Some companies lower end models are ok. others are garbage. Good Luck!

tl;dr. if you live in the states, get an Eagle Star LED ESM7600. If not the usa - get marshydro. Full spectrum is not always the full par-spectrum. I recently did the work to find a good led. I crunched the numbers and i came to the conclusion that a full par-spectrum light is not worth the money, its cheaper to just buy a 'regular' full spectrum + a standalone ir/uv led-bar. (if that is important to you). in general, bar styled leds are a little more premium, for alot of more money. But! you have to check current prices. Somtimes they go on sale and then its a no brainer. Bars also tend to have a better/more uniform par-map, then the "board" based leds. Full par-spectrum that is somewhat competitive priced. they have IR and uv diods. mars hydro: fc-e -> fc -> sp = (price/performance) Eagle Star LED ESM7600, depending on shipping, claims to have ir/uv. currently on sale. (id buy that if the shipping to me wasn't 200$ ) Viparspectra also JUST came out with a new bar-styled series of leds. no clue. You should head over to cocoforcannabis.com, they have an excellent buy-guides and also an price/performance calculator of diffrent brands of leds.

You have to pay alot for decent led lights and need to be good pull watts I have a maxibright led daylight 200w but not good enough to flower and cost £300 the marshydro 600w led or maxibright daylight 600w plus is nearly £1000 so it's not a cheap hobby

Fluence makes great led, comparable to HID lighting. Costly when cheap HID lighting is still very affordable. In the time it takes to save your money on the hydro bill. Those lights will need replacing at another hefty price. I will stick to HID lights.

Define best-I can tell you one of the best, and you will pay for it too, https://chilledgrowlights.com/ ChilLED lights are truly top shelf. The ONLY bad thing you will ever hear about them is they cost alot. Full stop. As far as light per watt there are not many light brands out there that can match up. As far as Light Engine Efficacy – 2.97 μmole/J – 2.75 μmole/J Full System Efficacy – 2.82 μmole/J – 2.61 μmole/J Thats for their BASE spec bottom of the range lights, the better ones higher up in the range go over 3 in Efficacy per watt. Thats an insane amount of light by anyones standard. If your not running Co2 and hydro or DWC then they are prob more light than most people could handle. Or If you want good but less pricey Viparspectra XS Series seems to have the goods too. Ive got my eye on one if I cant stretch the budget to a ChilLed light.
