LED Grow Lighting Rated for Damp or Wet Location?

I do have some information but would rather go through private messaging. However, it seems like to avoid spammers this function is not available when you first make an account, which makes sense. I've been browsing the forums for sometime and your topic made me sign up. Would an e-mail conversation be ok? Feel free to shoot me one at [email protected]

If not, we can wait until I get messaging abilities, but I am not sure how long it takes.

Why would you not go into that...you would be the only light that has both and you should want the attention that brings????
 
Not holding out on anything and will share as much as I can as soon as I can. I just want to make sure everything is done right and done well for the company and the community. Don't want to put the cart before the horse. Good things to come - thank you for your interest - will be in touch ASAP.
 
If you got an actively cooled third party verified LED panel that the greenhouse guys would find better production under other than HID you should put it up. Why hide the pea? The world awaits.
 
Wasn't able download their spec sheet but one thing that strikes me is they are using a passively cooled design. No fans. Getting a damp location rating with this design is fairly straightforward and no doubt if I was able to see their spec it would indicate that UL1598, or equal rating and information as to the panels PPF values. Nice looking units though. Any idea how much they are and if there are any images of greenhouses that have installed them? Are they available in the USA?
 
No idea honestly, EU based company and I suspect that they are very expensive professional equipment mostly used in scientific experiments.

I am working on a greenhouse contract. In order to satisfy AHJ requirements and my clients wish to use energy saving LED technology, I am looking for LED grow lights that are either UL or CSA-US certified, listed for use in damp (or wet) location. Zero luck after extensive research.

Anyone know of such a creature? 277 volt operation is a big plus.

I just checked the UL database - http://www.ul.com/database

LumiGrow is listed and also has high voltage fixtures. "Model(s)
Model(s) Models Pro 325, Pro 325 SP, Pro 650, Pro 650 SP, and Pro 325HV, Pro 650 HV."
 
HA! What do you know.. So is AT! Thanks for that Sow

No seriously it is a nice comfort to see those companies up there.
 
It is a nice comfort to see them listed but other than IG the others are not DAMP LOCATION rated for greenhouses. If they were in fact rated for DAMP LOCATION that information is put on the UL listing. If it is not expressly stated as being DAMP LOCATION rated it is by default approved for DRY LOCATIONS only and would be denied an approved installation by the local inspector or a subsequent OSHA inspection where they are on the look out for that type of thing.

The reason for products being certified for their environment comes from the severe instances whereby HAZARDOUS LOCATIONS lighting or electrical equipment is going to be installed and there is a likelihood of explosive vapors getting inside the enclosure where a spark would cause an explosion and fire. Consequently inspectors are VERY attuned to making sure that equipment has been third party verified so that the electrical equipment has been designed to not allow that to occur.

I forgot to add that while polyethylene film greenhouses are normally stripped and re-covered every few years, glass can last for decades and must be cleaned periodically. We last reglazed our 1/2 acre of glass greenhouses in the late '70s, although we have replaced individual panes since then. We clean the inside of the glass every few years with a solution using di-hydrogen fluoride, so the solution is basically weak hydrofluoric acid) then rinse it with plenty of water. Wet and corrosive.

Also, our greenhouse humidity can be very high due to plant transpiration even if little free water is spilled, e.g. we water with drip irrigation. Humidity levels will also depend in this case on crop type, growth stage, CO2 levels, sunlight, etc. EMT conduit systems do not do well in this environment and corrode within a few years. We run all power in PVC conduit now.

I will be the first to applaud any LED mfg who has a fan cooled panel that meets third party verification that it is suitable for a DAMP LOCATION environment. These manufacturers must, or should know that their panels have not been tested for this environment or it would be on the listing. Until those panels are listed as such they are selling a panel that is not legally eligible to be installed in these environments and to market them as third party listed to greenhouse customers who require a DAMP LOCATION listing is indefensible.

I wasn't able to find any products in the UL database that had the DAMP LOCATION qualification.

The LumiGrow Pro Series Greenhouse fixtures are UL Listed and suitable for damp locations, says so on the serial label.

Here are two snapshots of the serial labels for the Pro 325 and Pro 650 fixtures. They read, "THIS DEVICE COMPLIES WITH PART 15 CLASS B OF FCC RULES. SUITABLE FOR DAMP LOCATION."

If I understand correctly class B refers to residential NOT commercial as the OP is looking for.

Class B Digital Device. “A digital device that is marketed for use in a residential environment notwithstanding use in commercial, business and industrial environments. Examples of such devices included, but are not limited to, personal computers, calculators, and similar electronics devices that are marketed for use by the general public.

Still don't know how they are getting any fcc damp-location approval with active cooling......:confused:
 
What about inda grow? Their lights are known to work great in green houses. They are working on a light sensor that either turns on the unit when light is needed or turns off.

Im still in the works of building a green house, but am leaning towards cfls just because its cheaper, plus lets now forget the sun is what does most of the work imo

edit sorry came in convo late

Well if indagro is pushing their lights for commercial green house use, they should be approved for US damp-locations by now........chaz would know 100%

Guys ...
There is ..a company that has industrial greenhouse led lights with IP67 certification...

6: Dust tight_No ingress of dust; complete protection against contact (dust tight).
7: Immersion up to 1 m_ Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion).

Test duration: 30 minutes
Immersion at depth of at least 1 m measured at bottom of device, and at least 15 cm measured at top of device

Min. NEMA Enclosure rating to satisfy IP67 Code : 6

But...it ..is ..ehmm...err ....Russian ...

You know ...

Hello All:

New to the community - thanks in advance for allowing me to participate. I represent the company that romes187 posted about earlier in this thread. Is the current requirement for your customer an IP rating specifically of 65, or would IP63 be acceptable if the fixture were a passively cooled (no fans) design? This fixture would have a rectangular footprint unlike the Philips, Illumitex and BML rail system LED lighting products. This line of fixtures also is "wet-proof" so it is rated, and suitable for damp locations. Additionally, they will carry a UL, cETLus, and IP63 rating. I will have more important information to share shortly, however NDA's preclude me from doing so publicly as of yet. Suffice it to say, this product line should prove to be a game changer given our understanding of the commercial/high end hobbyist's requirements with regards to augmenting/replacing HID fixtures in their indoor horticultural applications. I am interested in this group's feedback as there appear to be many very well informed people on this forum, and this thread in particular.

Best Regards
 
Hi PSUAGRO

Thanks for the post - as soon as legal clears the docs I will. Believe me - I really want to disclose more and anticipate being able to do so shortly. I do have a general question for those in the know - as we figure out production runs what would be the average sq foot coverage requirements for a greenhouse in Colorado or Washington, and roughly how many of those larger opportunities currently exist. Your feedback is greatly appreciated. I am unable to send PMs as of yet however snaps provolone has my co- workers contact information.

Thank you for the reply and in advance for your support.
