I just got another review right now from a Chile customer, I'm happy if our users are happy :) This guy bought two old
models, 300W:smoking::smoking:

Hey M like our discussion and thinking of purchasing 2 144 reflectors as side lighting as well as maybe 2 mars 700's for over head problem i see is there both 5 watt diodes ,, Can a person pick n build these units ?? i mean i do not want 5 watt diodes but 3 watt diodes instead from reading leds in past couple years i am 75 percent ready to give them a shot but not interested in 5 watt diodes not at all so i its possible to to custom make reflectors or mars 2 units i would be interested then
, but the LED grow lights with the larger diodes have some very critical drawbacks. The first issue is that of heat dissipation and density. As the diode size increases, so does the amount of heat that needs to be dissipated by the diode chip. Larger wattage diodes need larger heat sinks to dissipate the heat that they give off. This results in heavier and bulkier lights. Another critical design drawback of the larger diodes is that they can not be packed as densely as the 3 watt designed lights. When using 5 watt or 10 watt diodes, you must space the diodes further apart, again because of the problem of heat dissipation. The result is a less densely packed grow light that is heavier and bulkier.
The biggest drawback of the 5+ watt diodes is their price. Not only do they cost more overall, but they are also more expensive on a $/watt and $/ growing area covered basis. A quick analysis shows that it is not worth paying a premium to have larger diodes in LED grow lights. The added penetration is superfluous and unnecessary for indoor growers and it comes at a burdensome cost – increased price and less densely packed network of diodes.
Bigger is not always better. When it comes to the question of 3 watt vs 5 watt diodes for LED grow lights, the 3 watt diode is the smarter choice for any indoor growing project.

I think Dr.Fever has right, 3w led are the best! (cooler,less energy coast,more effective,lower price)
doesent mean higher w means better penetration, because its all about the driver and leds manufacturer :cool:
as i saw before...if you use 3w of cree or phillips rebels leds you have much better par lumen lux penetration then with other 3w or 5w leds...
Philips Rebel LEDs convert between 43-53% of the electricity into light - over twice as efficient as the much cheaper Chinese chip encapsulations and COB (‘chip on board’) alternatives.
And the luxeon rebel es xitanium digital drivers
the secend is the optical lense , the best is the secendery with 90°
Or the driver can be pushed i read from kind led:
Our 3 watt diodes running at a 650ma driving current incorporate the perfect blend of intensity, efficiency, durability, and low operating temperature, making them the superior choice. Many other LED brands are running with lower diode wattages and lesser driving currents, making them an inferior option when compared with Kind LED Grow Light.
mean with the right leds,driver, lense can can have a 300w panel with 3w that give you 3x time more yield , then a 5w 700w Panel :love1:
best greetz :)
Hi DrFever:)thats what i am talking about and M i know what your saying but i am looking
5 watt you need to move them further apart as well due to heat and we all know heat is not efficiency its rather lost performance .. where as the 3 watt can be more compact like saying what will produce more 225 5 watt diodes @ 180 degree lens or 500 3 watt diodes with 90 degree lens
and being a company like mars is it that hard to get 3 watt diode bins i mean cmon being a light company you should be able to offer what the customer is looking for rather then .
Thinking you got a better price on 5 watts or signed a contract with distrubutor that you only can use 5 watt bigger is not always better ..
you guys like a lot of other companies jumped the gun and went 5 watt 10 watt etc 3 watt from my readings are the best bang for the buck and that is what i am looking at this is not only help with heat issues it will also having more lights then 5 watts be a more even canopy i think
Heyy Weedlover;),
You are right, higher W doesnt mean better penetration, that's why even tho many Manufactures use 5W chips now, but users still can get different yield by purchasing from different companies . :party1:
We have made experiment in our factory and changed design again and again, some users have made comparasion about our old model 3W and 5W LEDs, they found out our 5W LEDs actually have better penetration than old model, and gave them better result. That's why we switched all to 5W even tho it costs us more. :)
But hey Weedlover, yours and DrFever's suggestions are still very important to us, if we got more doubts like this, we will do experiment again and maybe make new decision! All we want is producing the best lights for growers!!!:)
ah ok i understand :cool:
whats about the pro models its with 3 or 5 watt ?
think the cree is the best mars light right now :love2:
best greetz :)
So if anyone prefers lights with 3W, Mars Pro Cree lights might be the best choice ! ;);)
Well weed lover i say i am purchasing the 192 x 3 watt ordering one then other one couple weeks later so i will run 2 for flowering :)
from what i have read will still talk with M if they will throw in better fans from my reading there loud either way not a big deal have buddy in that field so maybe he will clock the unit or like some say give it a boost or tune up :)
but yeah ordering next week
Very nice :love2:wanted one ...:love1:
This fine light must be testet in every single way :cool:
best greetz :)
