The new LEC fixtures have changed the indoor develop lights game, that begins to set the old HPS fixtures as obsolete, searching for new formulas, far more effective, that also bring a new spectrum of light, far more comprehensive. In this post we will talk about about these sort of develop lights, what are the feasible benefits and disadvantages from LEC lights, and applications for cannabis indoor increasing.
What LEC fixtures are?
LEC stands for Light Emitting Ceramic. Also identified as CMH (Ceramic Metal halide), these sort of develop lights act related to a existing Metal Halide fixture, but inside a quartz ceramic arc tube. In the field, one particular of its distinctive benefits is its light production (with a far more all-natural colour), that produces far more ligth per watt, apart from enlarging the life of the lamp. To describe this new technologies there are unique possibilities, all of them referring to the exact same notion:
– Ceramic Metal Halide (CMH): Metal Halide light that utilizes a ceramic arc tube.
– Ceramic Discharge Metal Halide (CDM): Option term for the exact same technologies applied.
– Light Emiting Ceramic (LEC): LEC is a registered name by one particular brand for a concrete develop light
that utilizes Ceramic Halide technologies. Even although, the LEC term, exact same it takes place in quite a few other fields, has began to be applied as CMH, since each refer the exact same technologies.
Up to date is nevertheless far more popular to use CMH for these sort of fuxtures, but LEC has improved its reputation, possibly for its relation with LED, that have been published as the develop lights for the future, till currently.
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 rapidly so now we also can uncover 630w LEC equipments.
The variations in between each models, far more than the energy is in the format they present, and traits each and every one particular presents:
LEC 315w: One particular 315w lamp SE (Single Ended).
LEC 630w: Two 315w lamps SE.
LEC 630w DE: One particular 630w lamp DE (Double Ended).
The most popular LEC develop light is the LEC 315w: These develop lights present a superior overall performance with greater g/watt ratio (superior crops for reduce consumption). These equipments take benefit from the greater present of 315w lamps in marketplace, from which we highlight the Philips CDM ones for its properties and yields.
The subsequent selection we uncover are LEC 630w SE: These develop lights comply with the pattern applied by 315w models, but applying two lamps (2x315w), what increases the yield per sqm setting two lamps operating with each other in the exact same reflector. The finest function of these fixtures is the possibility to combine unique sorts of spectrums on each and every light. This is an selection for these who like giving plants with a blend of unique spectrums (truly not possible to do if not operating with far more than one particular sort of light). Also a excellent selection for these who pretend rising their crops, but do not have ceilings higher sufficient to use the Double Ended ones.
The third selection accessible are LEC fixtures 630w DE: In contrast to other LEC equipments, these ones use a DE technologies (Double Ended lamp), inside a 630w lamp. This technologies brings a far more effective light distribution, apart from providing an improved light penetration on plants, and greater lumen production per watt applied, what derives in greater yields. These fixtures can compete against 1000w HPS fixtures, with a 30% reduce consumption.
Benefits of LEC fixtures
No doubt the finest benefit of LEC develop lights is its greater efficiency, what derives in an improved yields (or in a reduce consumption for the exact same 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 developed by sun light and, speaking about LEC, contribute to boost trichome developement and flavours of cannabis plants. It is critical to highlight that UV-B rays (stands for Ultraviolet sort B rays) can be block by glass applied in some reflectors, so it is critical to not use cooled reflectors to be confident there is a clear path light-canopy.
– Light production: In contrast to LED or HPS fixtures, the light made by LEC equipments will not transform the colour we see plants. this characteristic tends to make life significantly much easier for growers, that will be capable to diagnose his plants quickly. One thing you will also notice is the light create by a LEC is a significantly far more popular colour, so if ever happens a light-leak, it will not be noticed by third-folks as a thing uncommon).
– Constructed-in LEC fixtures: In contrast to HPS lights, most of LEC develop lights are constructed-in units, so they are plug and play fixtures (significantly much easier to set up them).
– Extended-life: LEC lamps keep its brightness longer than Metal Halide ones (also longer than HPS), what enables growers to transform them significantly less normally.
Disadvantages of Ceramic Metal Halide equipments
Speaking about cons of LEC fixtures we must creat three unique segments (one particular per sort of fixture):
LEC 315w: It is correct these fixture enhance yields (if we examine them with the overall performance got from an HPS 400w), and minimize consumption of you light bill (critical information). Even although, 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 each and every fixture and lampm just inform you that 315w CMH lamps do not bring the exact same light penetration of an 400w HPS lamp. This forces grower to switch his develop-style to a SOG (with brief plants), or SCROG exactly where all canopy is kept at the exact same distance from light so it receives the exact same quantity of light.
LEC 630w: These develop lights are in the middle. It is correct that if we double the energy applied, and spread that light production in two point, it will derive in greater yields in the exact same increasing space. But, and it is an critical but, the light intensity is what it is, so we will comply with the exact same patterns applied for the 315w lamps, slightly rising the distance lamp-canopy (no due the boost of light as nicely as for the boost of heat).
LEC 630w DE: Double Ended 630w LEC lamps have quite a few benefits, but no doubt one particular of their greatest inconvenient is the quantity of heat developed (comparable to a 600w HPS when operating at 660w position). This will force growers to use greater ceilings, and also far more airflow, in order to hold temperatures below handle. It is also critical to inform these lamps will will need at least 60-80 cm distance light-canopy.
Black, white and gray
As every little thing in life, nothing at all is white or black, there is constantly 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 actual expectations we can anticipate from these Ceramic Metal Halide develop lamps. We will inform you how these units worked in our gardens, so each one particular can conclude which is the finest fixture for their goal. This way publishing info about actual tests everybody will be capable to make a decision.
CMH fixtures side by side
Sunburst 315w: This develop light is best for growers that had been applying 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 acquire on the black marketplace. 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 excellent, and possibly thanks to the yielding capacity of the clone applied, not quickly reachable with a medium yielder strain.
Selecta II 630w Solux: This fixture consists of 2x 315w lamps applied in the exact same reflector. It is a compact fixtures that must be applied to cover 1,20 x 1,20 meter spaces with a distance light-canopy of 50-60 cm. In our test we applied a Homebox Q120 with 25 cuttings of Vital+. 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 excellent, but it is also correct the outcome was gotten applying the superlumens selection from begin 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 final results will be wonderful, and we weren’t incorrect. No doubt this is the fixture we advocate to each grower who has been applying a 600w HPS, as its consumption is pretty much the exact same, but its overall performance is amazingly superior. It is correct that you will will need greater ceilings to use it, so to do this test we applied a Homebox Ambient Q120+ (two,20 meter height). This time we applied 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 (applying the 630w position from begin to finish).
LEC vs LED
If you are searching to boost your yields possibly your finest selection (yield/cost) is acquire a LEC fixture. What could transform this choice: Heat. LEC fixtures create far more heat than a HPS 600w, what equals the classic troubles of increasing in hot seasons, and make a will have to the use of an air conditioner is we want a high-quality crop without the need of troubles. In contrast to LEC, LED develop lights create significantly significantly less heat when the exact same quantity of energy is applied, 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 although LEC lamps will have to be replaced each four cycles).
It is clear that these who personal an HPS fixture do not will need to transform it for this new technologies, but if you are arranging to transform your old one particular (or acquire a new one particular) our advise is superior you bet for the new LEC, its overall performance is superior, and final results help it.
