The new LEC fixtures have changed the indoor develop lights game, that begins to set the old HPS fixtures as obsolete, hunting for new formulas, additional effective, that also bring a new spectrum of light, additional total. In this post we will go over about these sort of develop lights, what are the achievable benefits and disadvantages from LEC lights, and applications for cannabis indoor expanding.

What LEC fixtures are?

LEC stands for Light Emitting Ceramic. Also identified as CMH (Ceramic Metal halide), these sort of develop lights act equivalent to a existing Metal Halide fixture, but inside a quartz ceramic arc tube. In the field, 1 of its distinctive benefits is its light production (with a additional organic colour), that produces additional ligth per watt, in addition to enlarging the life of the lamp. To describe this new technologies there are unique possibilities, all of them referring to the similar idea:

Lec CMH fixtures

– Ceramic Metal Halide (CMH): Metal Halide light that makes use of a ceramic arc tube.

– Ceramic Discharge Metal Halide (CDM): Option term for the similar technologies made use of.

– Light Emiting Ceramic (LEC): LEC is a registered name by 1 brand for a concrete develop light

that makes use of Ceramic Halide technologies. Even even though, the LEC term, similar it takes place in quite a few other fields, has began to be made use of as CMH, for the reason that each refer the similar technologies.

Up to date is nonetheless additional popular to use CMH for these sort of fuxtures, but LEC has enhanced its reputation, likely for its relation with LED, that have been published as the develop lights for the future, till these days.

LEC fixtures and energy possibilities

We we speak about LEC fixtures (or CMH fixtures), the most popular ones are the 315w, but the building is getting so rapid so now we also can come across 630w LEC equipments.
The variations among each models, additional than the energy is in the format they present, and traits every 1 gives:

LEC 315w: 1 315w lamp SE (Single Ended).

LEC 630w: Two 315w lamps SE.

LEC 630w DE: 1 630w lamp DE (Double Ended).

The most popular LEC develop light is the LEC 315w: These develop lights present a improved efficiency with greater g/watt ratio (improved crops for reduced consumption). These equipments take benefit from the greater present of 315w lamps in market place, from which we highlight the Philips CDM ones for its properties and yields.

The subsequent selection we come across are LEC 630w SE: These develop lights adhere to the pattern made use of by 315w models, but employing two lamps (2x315w), what increases the yield per sqm setting two lamps operating with each other in the similar reflector. The finest function of these fixtures is the possibility to combine unique sorts of spectrums on every light. This is an selection for these who like delivering plants with a blend of unique spectrums (really not possible to do if not operating with additional than 1 sort of light). Also a fantastic selection for these who pretend rising their crops, but do not have ceilings higher adequate to use the Double Ended ones.

The third selection out there are LEC fixtures 630w DE: As opposed to other LEC equipments, these ones use a DE technologies (Double Ended lamp), inside a 630w lamp. This technologies brings a additional effective light distribution, in addition to supplying an enhanced light penetration on plants, and greater lumen production per watt made use of, what derives in greater yields. These fixtures can compete against 1000w HPS fixtures, with a 30% reduced consumption.

Benefits of LEC fixtures

No doubt the finest benefit of LEC develop lights is its greater efficiency, what derives in an enhanced yields (or in a reduced consumption for the similar quantity of dried buds, based on the model selected).

Stated this, lets detail some of the benefit of LEC fixtures compared with HPS/MH develop lights:

– UV-B rays productions: UV-B rays are created by sun light and, speaking about LEC, contribute to improve trichome developement and flavours of cannabis plants. It is essential to highlight that UV-B rays (stands for Ultraviolet sort B rays) can be block by glass made use of in some reflectors, so it is essential to not use cooled reflectors to be confident there is a clear path light-canopy.

– Light production: As opposed to LED or HPS fixtures, the light made by LEC equipments will not adjust the colour we see plants. this characteristic tends to make life a great deal simpler for growers, that will be capable to diagnose his plants conveniently. Anything you will also notice is the light generate by a LEC is a a great deal additional popular colour, so if ever happens a light-leak, it will not be noticed by third-people today as a thing uncommon).

– Constructed-in LEC fixtures: As opposed to HPS lights, most of LEC develop lights are constructed-in units, so they are plug and play fixtures (a great deal simpler to set up them).

– Extended-life: LEC lamps preserve its brightness longer than Metal Halide ones (also longer than HPS), what permits growers to adjust them much less generally.

Disadvantages of Ceramic Metal Halide equipments

Speaking about cons of LEC fixtures we need to creat three unique segments (1 per sort of fixture):

LEC 315w: It is correct these fixture boost yields (if we examine them with the efficiency got from an HPS 400w), and minimize consumption of you light bill (essential information). Even even though, not all that glitters is gold, as we will will need to adapt to the traits of these lights. As we do not want to bore you with technical information about every fixture and lampm just inform you that 315w CMH lamps do not bring the similar light penetration of an 400w HPS lamp. This forces grower to switch his develop-style to a SOG (with quick plants), or SCROG exactly where all canopy is kept at the similar distance from light so it receives the similar quantity of light.

LEC 630w: These develop lights are in the middle. It is correct that if we double the energy made use of, and spread that light production in two point, it will derive in greater yields in the similar expanding space. But, and it is an essential but, the light intensity is what it is, so we will adhere to the similar patterns made use of for the 315w lamps, slightly rising the distance lamp-canopy (no due the improve of light as nicely as for the improve of heat).

LEC 630w DE: Double Ended 630w LEC lamps have quite a few benefits, but no doubt 1 of their greatest inconvenient is the quantity of heat created (comparable to a 600w HPS when operating at 660w position). This will force growers to use greater ceilings, and also additional airflow, in order to retain temperatures below handle. It is also essential to inform these lamps will will need at least 60-80 cm distance light-canopy.

Black, white and gray

As anything in life, practically nothing is white or black, there is often a grey, and this is how we attempted to create this post. This is why we attempted to inform which ones are the pros and which ones the cons about LEC fixtures, axplaining in the easiest way we could what are the true expectations we can count on from these Ceramic Metal Halide develop lamps. We will inform you how these units worked in our gardens, so every single 1 can conclude which is the finest fixture for their objective. This way publishing facts about true tests every person will be capable to determine.

CMH fixtures side by side

Sunburst 315w: This develop light is excellent for growers that had been employing 400w HPS lamps, but who will need to minimize their light consumption for any cause, but preserving the yield per crop so they do not will need to invest in on the black market place. We produced a test with the USnburst in a Homebox Q100, with 20 cuttings from Northern Lights (heavy yielder strains) in five,five L pots, providing them 1 week of vegetative stage. The outcome have been 450g of dried buds, completely trimmed. Lets be clear: We do think the outcome was so fantastic, and likely thanks to the yielding capacity of the clone made use of, not conveniently reachable with a medium yielder strain.

Selecta II 630w Solux

Selecta II 630w Solux: This fixture involves 2x 315w lamps made use of in the similar reflector. It is a compact fixtures that need to be made use of to cover 1,20 x 1,20 meter spaces with a distance light-canopy of 50-60 cm. In our test we made use of a Homebox Q120 with 25 cuttings of Essential+. We gave them 1 week of vegetative stage ahead of flipping them to flower. The outcome was astonishing: 850g of dried and completely trimmed buds. It really is correct the outcome was fantastic, but it really is also correct the outcome was gotten employing the superlumens selection from get started to finish (690w), what shortens a lot the life of the lamp.

Kit Solux LEC 630w DE: We have been exited to proceed with this test, as our intuition told us benefits will be wonderful, and we weren’t incorrect. No doubt this is the fixture we propose to every single grower who has been employing a 600w HPS, as its consumption is nearly the similar, but its efficiency is amazingly superior. It is correct that you will will need greater ceilings to use it, so to do this test we made use of a Homebox Ambient Q120+ (two,20 meter height). This time we made use of 25 clones of Amnesia in five,5L pots, providing them two weeks of vegetative stage ahead of setting them to flower. The outcome? 900g of dried buds, completely trimmed (employing the 630w position from get started to finish).

LEC vs LED

If you are hunting to improve your yields likely your finest decision (yield/value) is invest in a LEC fixture. What may possibly adjust this choice: Heat. LEC fixtures generate additional heat than a HPS 600w, what equals the classic troubles of expanding in hot seasons, and make a should the use of an air conditioner is we want a top quality crop without the need of troubles. As opposed to LEC, LED develop lights generate a great deal much less heat when the similar quantity of energy is made use of, so growers can save the expense of an air conditioner (plus the additional watts due its use). To these power/heat savings we have to add the life o the compounds (LED can final five years even though LEC lamps should be replaced every single four cycles).

Conclusions

It is clear that these who personal an HPS fixture do not will need to adjust it for this new technologies, but if you are preparing to adjust your old 1 (or invest in a new 1) our advise is improved you bet for the new LEC, its efficiency is superior, and benefits help it.
