more and more led manufacturers are
emerging
a mix of good and better individualized
rise in the market
so today we are going to introduce
various led manufacturers
then you’ll know why mars hydro should
be your choice
let’s take a look at the current
situation of the led grow light market
there are three kinds of manufacturers
oem iite tm
first some manufacturers produce
finished products in china and then
rebrand and ship locally
recording oem
oems are divided into top oems and cheap
oems based on their quality management
the other kind of manufacturers who
develop and produce their own products
and also sell and trade like mass hydro
we call an iite
and third
the last group of manufacturers have no
official name no manufacturing address
or license most sell on alibaba recorded
tm
they barely have any quality control and
never to mention after cell service
price is an important but not decisive
factor in purchase decisions
low price doesn’t mean low material cost
high price doesn’t mean high quality
the top oems usually have the best
quality control in the market
as a result the price are the highest as
well a customer often have to pay a
price of twice or even three times of
the original product just for the brand
even the oems on the cheap side charge
an additional 50 to 100
to the actual production price
in comparison iite offers much more
affordable pricing thanks to their
factory outlet
there are no extra third factory cost or
middleman to raise prices good quality
control is often a guarantee since they
are the owner of the factory
tm or temporary manufacturers often have
the lowest price and the lowest quality
the quality of the grow light can be
judged by its components
core specs and security certifications
diode is the most important part of any
led grow light
the top oems use high quality diodes
from samsung or australia to guarantee
high yield and
but some oems still use cheap diodes to
save cost
iite use the same top tier quality
diodes as used by the top oems to
support high quality growth
the temporary manufacturers often use
the cheapest styles they can find in the
market and sometimes defect samsung
diodes
now let’s talk about the samsung chips
and how good they actually are
samsung 3030 chip series
for 301 h
it has 230 illuminate per watt
and the ppe is 3.1 micromole per joule
the 301b has 220 luminaid per watt
and the ppe is 2.92 micromole per joule
and for 301d
it has 211 luminaires per watt and the
ppe is 2.7 micro more per joule
for samsung 2835 chip series
the luminaire is less than 210 per watt
and here’s the conclusion
the best diode is 301h and then 301b the
301d
and they are all better than 2835
a well-designed power supply provide
efficient and stable power while
avoiding heat issues and saving energy
the toppo ems use high quality power
supply brands and separate external
power supply design
the cheapoem would keep this separate
external power supply design
but some use inferior brands
iite use high quality power supply from
brands like mingwell while also keeping
external power supply design
the temporary manufacturers use inferior
power supplies which can cause fire
hazard
the second factor of product quality is
its core data like the quantity of the
diodes and ppfd design
when explaining diode quantity the
concept of overdrive comes into play
generally speaking when the wattage of
the whole light is determined the heat
and electric current is determined as
well
an example appears in the video which
you can see briefly
the one with more dials has lower
current around each dial
which avoid overdrive and overheating to
make diodes have longer surface life
diode quantity should be seen on
manufacturers or facial sites
you can find them and compare them by
yourself
top oems are with reasonable diode
quantity and arrangement no overdrive
cheaper oems use the same arrangement
but much less diodes to cut the cost
this makes them vulnerable to overdrive
iite is reasonable diode quantity and
arrangement there’s little risk of
overdrive and their data is clear for
everyone to see
a tm would try to mimic the appearance
of high-end products but their core data
is simply false and their products are
very vulnerable to overdrive
most grow lights in the market have a
high level of average ppfd or ppe and
most of them have high ppfd values in
the middle but very low values around as
a result plants in the middle gets
burned if you hide higher to avoid burns
you lose ppf
here’s a list of estimated ppfd values
for commercial cannabis growers
for vegetative stage there should be 800
to 100 ppfd where flowering stage should
have 100 to 1200 ppfd
anything over 1200
your cannabis will need the help of
additional co2 but the highest ppfd
cannot exit 1500
therefore only grow lights with ppfd
values that are higher than 800 at all
points
but does not exit 1500 are the best
choice for commercial growing
the oems usually have the most typical
ppft designs and very good numbers but
their ppfd are already centered in the
middle this uneven light distribution
may reduce your yield potential because
the plant in the middle cannot absorb
all the light while the plants in the
surrounding don’t get enough
iite has a better design both the
central ppfd value and the corner ppfd
value are in the best interval and the
difference is small uniform ppfd
distribution is changing the market
temporal manufacturers ignore the light
distribution and actual efficiency of
the lights by just copying other
products appearance
some growers may prefer lights with uv
and ir diodes but do they really matter
that much as we think
not really because as you can see uv and
ir are only beneficial under the right
circumstances
for some stages of growth uv has no
positive effects to your plants in fact
excessive amounts of uv light can even
harm your plants
infrared or ir light can be used
continuously throughout all the growing
stages
however
if you are sure you want to use ir light
on your plants
keep one thing in mind
the correct ratio of the amount of ir
light and red light is very important so
our suggestion is to use extra bars to
control uv and ir separately with full
spectrum led grow light this is how you
can get the real benefits of uv and iron
certifications provide a safety
assurance for the products you buy and
transparent data offers no gap between
merchants and buyers
oems are well certificated but rarely
publish their data iite are well
certificated as well and offer
transparent core data because they are
the factory themselves
temporary manufacturers usually have no
certifications or fake certifications
along with fake data
customer support is important to any
companies
quality service can make buyers worry
free
oems have local warehouse and service
center which ensure a fast delivery and
after sales support but over time they
may exit the market so their service
guarantee sometimes is not reliable
iite has local warehouse and service
center as well and because they are the
factory themselves they will not easily
change the products they make and sell
they are also easily to be found on
social media by official accounts
tm as we mentioned before it’s just a
temporary manufacturer they have no
local warehouse or service center
if they face too many customer
complaints they will simply give up
their brand and choose a new different
brand name to start over so their
warranty information are very unreliable
finally we come to a conclusion when you
invest in an led grow light the return
of investment and the service are all
you need to concern about
Evlla OEM Network has two versions the top oems have
good product quality grow results and
service but due to high product prices
the overall return on investment is low
cheaper oems have better prices but
their product quality and service are
not as good in general they both tend to
take advantage of their brand effect and
charge a premium on the customers
iite has good product quality grow
results and service as well due to
factory direct sale the prices are very
good cost effective choice temporary
manufacturers
low quality low yields no after sales
guarantee they use the cheapest material
they can find in the market to produce
you inferior quality products better
stay away
