Lighting new GN Units

[BBG]

sounds like usa people need a transformer (voltage converter) well thats my 2 cents

 

[Dr Fluff]

Was wondering if the LED drivers could be replaced with US friendly ones, if so could grow Northern sell them like they sell the rebel upgrades?
Any electronic geniuses in the house that can answer this?

There is plan to release a US version but that will a month or two after the initial UK release from what I have been told...

Thanks Ronin.If that unit works it would be great.

well i use a transformer for a deepfryer that i ordered from us for 110 to 220v converting works fine and the fryer is a 110v only and ive used it for many years now

soon as i get specs emailed ill post them for you.hope this post helps everyone

The new Grownorthern unit is state of the art and uses some of the highest quality components available one of which are the Philips Rebel LEDs as we found the Rebels unmatched in are desired spectrum. The unit is very efficient and uses just 75w but the output and coverage are similar the are previous 180w light the MS0006 it's also smaller dimensionally than the MS0004. The unit will be quiet too as the technology we are using to cool the unit is virtually silent. We hope to release the unit by the end of this month and the retail will be £330 in VAT. I should also mention the unit is 220-240v only
I will email you as soon as we release the technical specs and set the launch day.




If you have any questions or feedback please get in touch,


Kind Regards

A hps light throws out light in 360 degrees along the tube length, which means light that is travelling in a direction other than towards your plants needs to be redirected via reflection. A larger reflector will reflect more of this otherwise lost light that is not going towards your plants.
LED lights primary focus is often 120 degrees (2/3 more efficient directionaly) and with secondary lenses/reflector for each diode the can be concentrated to 90 degrees 60 degrees etc...
COB (Circuit on Board) intergrated arrays, which are made up of a matrix of micro smd (surface mounted diodes) LED's often use reflectors or dome shaped columnar focal lenses which focus the light to the required degrees, much the same as with single diodes with secondary lenses.

Can't wait to see whats in store with the new GN light, apparently gonna be a game changer.

Yes this is standard led tech, and for a scrog and a flat canopy is fine but when you have multiple plants that are 1.5m in height a compact light unit is going to create massive shadows as the light cant 'bend' around the plant. This is why a huge reflector gives great results on tall plants.

Dont get me wrong I am extremely excited about this new light and hope to secure a few of the first batch, just curious if any light engineers out there have info on how you would combat this without multiple units (trying to plan my new light setup).

No problems man nothing like a good discussion, just wish there was a nice cup of tea and nice bit of herb we could share at the same time.
You make a very salient point, but for a long time different grow lights have had different grow methods that suit them, as T5 and domestic CFL growers will testify, just to name couple of different lights.
You may have notice in some of Tangs grows the LED lights aren't hung horizontally flat but angled to maximize light penetration.
Horses for courses I think is the expression.
We will have to wait and see what the future brings with the new GN lights, I'm sure they have tested them in the R&D stage and they have passed muster in order to reach the manufacturing stage.
Any short coming will become evident as there is so much interest here and as the forum members start to make journals using them.
Don't count you chicks before they hatch, I believe they say.
I think it is great that you are thinking about these issues, not long now till we see the proof in the pudding.
