If you focus on the "green" LEDs in the very corners of the fixture, you can see that they are whiter looking than the same type in the middle, probably because of this colour bleed that is being talked about. I noticed this phenomenon last night.

thank you, super~ so much happy to know you love themI have 2 Mars tents and 3 Mars lights. I am very happy with them. You can see them in my grow journals in my signature. I did a lot of research before buying my tents and lights and I think Mars-Hydro gives you the best bang for your buck.

Hi I currently have a 130/300w 60×5 mars hydro light. I'm thinking that this is too much for early seedling stages and im after a light specifically for seedlings and early veg stages. Any suggestions on a good light for this as I want to run everything led from start to finish. Ive been looking at the 48×3 reflectors with veg/bloom settings are those still available in the uk? And would those be ok to use very close to seedlings as I will be using a very limited space for early veg? Im hoping that using 3w leds rather than 5w leds means I can get away with being closer. Ive even been looking at the cheap knock off things on eBay (yeah I know) in the hope if low power leds being my answer.
Dudewheres,
I have the same lights. No problem if you have the seedlings in the beginning further away from the light and only put them close to about 35" or so inches (80cm-90cm) when they have at least two real leaves. (After 3-4 days or so). And then gradually closer as the plant matures in the following days. Can't you adjust the light's height? Or set the plants to the side in the very early stages?

Just putting this out there:
Since green light has no effect on the plant...How much more would the additional cost be if the green LED diodes were replaced with diodes that matched the color spectrum output of Metal Halide (4200K) and or High Pressure Sodium(2100K) bulbs?

With the exception of the one guy (?) who actually really SEEMED to have a bunch of green LEDs on his lamps (for reasons unknown), I personally don't know any LEDs that "officially" and purposefully do contain green LEDs.
The lights sold now, the types and different brands I know from tons of researching etc. (sometimes) have addtional whites/ambers 2500k "warm whites" and no actual green LEDs. I really think this is a non-issue blown out of proportion or a mass-hallucination/hysteria

Thats what im doing at the moment I plan on buying another light to match mine and keeping both of them for permanently flowering. And buying extra lights purely for veg im hoping to use a space only 2 feet tall for seedlings but so I could not place the light very far away. If there is no other option but to have the light say 5 feet away I guess I could find another space if absolutely nesssary

I had run my old 48x3w for this reason.
But now my ladies are approach week 3 from seed.. I've combined both the reflector + MARS 2 80 x 5w. Ill probably just buy the 700w Mars2 or new series when I have more cash in a few months
Unless Sara wants me to try the new series or something
3w x 48w power output colour
With Twin Led's running output colour

Not sure whats going on but your seedlings should be 10x the size they are now. I can only guess the soil is toxic.
I use a Mars old style 300w 100 x 3w (190w) on my seedlings and they grow like wild fire
I put them under the light 3 days after germination with the light at two feet for 4 days then 18" then 12"
The 5w led's will be about 50% more intense then the 3w , given that I would start at 3 ft with new seedlings and work the light down to 18" over the next 2 weeks

Seedlings have been over fed but I think they are fine for 2 weeks after germination. Germination took longer due to it being winter currently in the southern hemisphere.

From your pictures the 48×3 looks much more like what I have in mind for seedlings as close proximity is the plan rather than 3-4 feet away

Just pulled out the tape measure 81cm away so just at 2.6 feet for the Mars reflector. Gonna lower them down to 18"

Jock Horror auto's 12" wide , the lights were at 12" after 1 week and are at 12" in the photo.
The lights are running at half power / 100w each as the plants/seedlings take up such little space. I unplugged two of the side LED ballasts from each panel leaving the center illuminated.
They will be 3 weeks old in 2 days

Hi Atulip, now the Reflector has been updated to 5w, but our website is still under updation. The data is still for the 3w leds.
They both use 5w chips now. MarsII has big power. It is usually used for big grow space. In addition, they have different design. The reflection feature of Reflector design will ensure maxmium light output.
Thank you. I plan on getting 144 reflector for my 2'7"x4'11" since its longer than the mars 2.
I just purchased a Mars II 400 for my current setup to add to my 2 100x3w "old style" Mars led lights. Very satisfied with the results from these lights. Can't wait to get my new one.
From my first grow. 4.9 ounces from 3 autoflowers in a small closet 76 days from seed. This is with just the 2 Old Style 100x3w Mars led lights.
