Omg that case is honestly the fucking most sleek bad ass one I've seen Yet. Wish my gogreen was in that. Damn...
Was looking into gogreen. They look efficient . Whats the ppf and ppfd ? And umol/j(watts) looking for the best kickass light. Would build my own but not a diy with electrical stuff.. plus time consuming. Need to get things done asap

The Leo light only draws 125w though. Which is understandable considering it is totally passive. Noooooiiiissseee freeeee! Which is rad. But go greens are 50w per cob. This is only 31.25w per cob significantly less. You get more intensity from a go green and it's considerably less $$$ with the RIU20 discount code. Although the Leo looks cool, I'd buy a gogreen or even more so a TASTYLED from @Rahz if I were you.

http://www.ledgrowlightsdepot.com/collections/8-sq-ft-coverage-area/products/leoled-fspectrum-c found 10% off which would make the light 431.10
and compare that with gogreen running at 200w . arent the 4 fans pulling wattage as well? wouldnt that be part of the 200w? "Each module contains four top-bin CREE CXB3070 (468W) COB LEDs, exudes an average of 309 µmol/s, and reaches an efficiency of 2.5 PPF/Watt!"" would be awesome if leoled came on to RIU and offered a 20% discount code...maybe we should reach out and let em know theres interest in thier products.

Look who advertises on this forum and read the last few months of posts. The lights you are considering are not the best. Most of the best lights use vero or Cree COBs. Best for your plant and efficient. Good to see you stopped here before falling for platinum hype. They copy products and even ads from a somewhat better company. All they have ever done is try to ride the coattails of Advanced LED, which is itself a second tier led supplier.

I also hate blurple!

Platinum is piss poor and they know it. Their business practices are unethical at best. Ripoff Bastards!

DO YOU HAVE ANY SUGGESTIONS ON WHAT ISHOULD GET

The prices are reasonable considering you also get a 3 year warranty, 60 day buy-back policy, and free shipping (only if you order through www.cobgrowlights.com run by GrowthStar based in Canada - CAN/USA shipping only).

Custom spectrum/specs available on larger orders. Wholesale discounts apply for those ordering multiples.

Results 60-days into the grow using GrowthStar COB LED grow lights (1600 Watts total)

In case you want to check out some earlier photos of that same trial. They have hundreds of HD photos and closeups. PM me if you need any and I'll send you some.

The problem with a lot of companies is that they don't honor warranties. Most LEDs (electronic goods), even DIY, made in USA, or other, have issues that you can't predict until they happen. So when they do happen, you want State Far--- A company that honors warranties ;)

LED's are supposed to be a long-term investment for 5-10 years. So if you are going to switch to LED because you don't want to pay 50% more on energy each month and have to change the bulb every few - not to mention buy a new lamp every 2-3 years then you want to buy the right LED.

COB (chips on board) LEDs are better than the standard 3W and 5W LED arrays because they suffer less light loss after 1 year.

And another important thing to mention is that when you are looking to buy an LED, contact the company and ask if the watts advertised on their website are the Actual Watts.
If you don't, you might be buying an LED based on their total watts and not the actual wattage that you were expecting. If they don't mention actual draw, then the actual could be anywhere from 40-60% less than their total advertised amount. This is why a lot of people get frustrated buying from China, Ebay, or Amazon because those listings usually list total watts so they can scam people to get short-term sales instead of long-term customer satisfaction.

If you can't afford a grow light yet you can subscribe for chances to win a free one every month: http://eepurl.us12.list-manage.com/subscribe?u=5c9e3d185e15c88a9928d97da&id=e19e94fd17 (Canada/USA only)

Oh and one more thing: don't mind the trolls who are trying to defend overpriced Grow Lights either. I do think if you know how to do DIY then that is definitely a better investment. I build my own computers and would not buy a cpu off the shelf from some retail store. If you are crunched on time and just want a pre-built and tested COB grow light that works so you can focus on growing then definitely buy one that is reasonably priced - that works great - and is backed by a solid warranty and service.

Check for , par, ppf , pffd , Umoles/j , DLI if they dont list those then dont buy the light. They havent done the proper research. Actual watts play a role but its more about ppf/watts (umole/j) . Efficiency is key.

A lot of the technical jargon is used by companies to take advantage of inexperienced growers that are new to LED. If you are a home grower, all you really need to know is that the company will honor their refund/warranties, that the light works (e.g. there are others growing with the light with photo updates), and that if you use the same product, you should be able to get the same results. Even technical information can be wrong/inaccurate/flawed. What is most important in my mind is that you are getting a good light at a fair price that will lower your energy bill while also lowering the temperature in your grow tent.

Par value is definitely important and you don't want to rely solely on Watts. If there wasn't so much misinformation online and people wouldn't get confused, I would tell them that par is more important than the watts.

It helps to know what the spectrum ranges are as well. Red and Blue provides plants with most of what they need. Others will beg to differ and that is fine. If they want to provide HD photos of their plants growing under their lights for comparison that would be the only way to really show what works better. Otherwise it is all theory designed to confuse people with information overload - when all you really wanted was to grow bud.

Its not mumbo jumbo confusion ....

PAR
Photosynthetically active radiation (PAR) is a
biological term and describes the part of the
electromagnetic radiation spectrum (light) that
is useful for plants to photosynthesize. PAR
defines the spectral wavelength range between
400-700 nanometers (nm), whereas the actual
measurements of the light are represented in
PPF and PPFD.

PPF
Photosynthetic Photon Flux (PPF) measures
the total light output (photons) emitted by
a plant lighting system. PPF provides the
amount of photosynthetically active radiation
(PAR) emitted per second and is therefore
measured in µmol/s (micromoles per second).
PPF however does not provide the amount
that is arriving at the plant.

Photosynthetic Photon Flux Density (PPFD)
expresses the amount of light that reach
the plants per second. PPFD is measured in
micromoles per square meter per second
(μmol/m2/s). Because PPFD is a measurement
of a specific location on the plant canopy, it is
crucial to know the average PPFD on a given
surface.

PPF/Watt
The PPF/Watt ratio provides a clear picture of
the overall electrical efficiency of a plant lighting
system. How much of plant-beneficial light is
converted by the system per Watt? Superior LED
lighting system reach a PPF/Watt efficiency of up
to 2.8 PPF (µmol/s)/Watt, while in comparison
1000W High Pressure Sodium (HPS) can reach
only up to 1.7 PPF/Watt.

PPFD/Watt
The PPFD/Watt ratio is the the most important
term in evaluating the effectiveness of a
lighting system on the canopy besides the PPF/
Watt efficiency. This is the most important ratio
to know as the delivered PPF (PPFD) is finally
important in horticulture and is measured at
least at several points over the plant canopy.
leoLED measurements are taken at 180 spots
on the canopy.

LUMENS & LUX
Lumens and Lux (lumens/m2) are standard
units for the luminous flux of a light source
and are used by general lighting designers.
The luminous flux is the part of the power
which is perceived as light by the human eye,
and is based upon our eye sensitivity at 555
nm. Therefore Lumens and Lux do not provide
a comprehensive picture for horticultural
applications.

Proper research

Tasty seems to have the goods for small places especially. Saw something from bud master with white cobs for Europe. PLC is great if they have lights in stock. Also GoGreen Johnson. More hitting the market each day.

I'm totally new to grow lights and decided to go the DIY route. I ordered 2 Vero 29 4000K COBs and a MeanWell HLG-185h-c1400b. I know this driver will power 3 Vero 29s, but I only want to run two. Will it blow them or will it be ok? Thanks for any advice you can give.
