The wires are 200mm long 18AWG and they are high-temperature chemical resistant. You can solder through the conformal coating to attach wires to the unused pads but that's why we sell both single end and double end wire strips to save you the hassle. You can just order what you need. One thing...

I will need to check and get back to you. The strips themselves are pretty wide and they are made of aluminium so the LED count per square isn't high and the PCB itself has good thermal properties compared to FR4. You should be able to run them up to 70W on heatsinks which is based on what we've...

Hi Thundercat if you would like to email me and let me know what you are interested in then I can give you a shipping quote. Email info@growlightsaustralia.com If you check out the prices on our website, don't forget the following: All prices are in Australian Dollars (cheaper than USD) All...

The Apogee ePAR meters do not really cover the UV range. The spectral response curve starts to drop off at 450nm and then really drops off at 400nm. That is why Apogee describes it as a "400-750nm" meter. If you want to measure UV you need a different meter. The Mammoth light you posted has no...

Hi Rocket Soul I finally got the message to answer this from PC! It looks like he has answered to bit about burning sulfur but I took some photos of the voltages with one strip parallel wired with one board and I can confirm you can definitely wire them in parallel. I also took a photo of the...

We would agree with this. I know there is a lot of debate about what "sunlight" is because it changes a lot but sunlight is always "true" full spectrum and white phosphor LEDs are not.

It has been a secret for too long that you need to balance both ends of the spectrum. I think the reason it has taken so long for some growers to realise this (not you Rocket) is that most LED manufacturers do not include both ends of the spectrum and so do not see the syngeries. Far red is...

Hey Rocket, Teknik has a new goniometer and Viso Systems is still tweaking the software, so he can't export the full reports yet. That is why I posted a photo of the screen. Once I get the full reports I will post them up. The strips will be going up on the website very soon! We are just...

Forgot to answer. Yes they are available now. All the new lights ship with the Gen3 spectrum.

1A 3.19 umol/j 2A 3.01umol/j 3A 2.89 umol/j 4A 2.79 umol/j 5A 2.72 umol/j We've been working on these a long time as the first prototypes weren't going to work on the pick and place machine as they were too narrow (40mm). These new ones are 480mm x 50mm and are 2.87 umol/j at 50W, which is...

LED Teknik has just done a new round of efficiency and spectrum testing for us and we were surprised to see the 1A test report come back as 3.19 umol/j. Without blowing our own trumpet (OK, we are!) that's a pretty good efficiency figure for a "true" PAR+ full spectrum light. Especially...

LOL! Yes you gave them to me for the Insta page remember? It looked like a nice grow.

This is the High Red led fixture alone.

This is all I could get. Sorry for the poor quality image. It is the CMH and High Red combination in the first two photos. You can't see the IR because the meter only goes up to 780nm.

We've seen good results mixing LED and CMH. A few years ago @Prawn Connery designed the original High Light LED panels with two different spectra. One included UVA as a stand-alone LED fixture and the other was dubbed the "High Red" because it used a mix of 2700K CRI90 and CRI95 Nichia Optisolis...

Put the drivers outside the grow tent. Problem solved. They can get quite warm to the touch and they will add a small amount of heat to the grow area but they don't usually get that hot to begin with that it will interfere with driver performance. It's the LEDs you need to keep cool to increase...

Maybe it was Migro I was thinking of. Their LED spectrum is close but LEDs are almost always going to have more blue than HPS because white phosphor LEDs use a blue pump at 450nm to generate light that is absorbed by the phosphor and converted to green and red light. If there was some way to...

I found an interesting article from another lighting manufacturer Valoya which partly addresses the HPS vs LED argument. It refers to a scientific study in 2017. I know there are questions around the study but it is one of the few resources we have...

The same as the Mean Wells. The 250W uPowerTek is up to 93% efficient on 220V mains which is the same as the HLG-240H-54A we have been using. The new 400W uPowerTek drivers we are getting are up to 93.5% at 220V. Mean Well rates efficiency at 277V and 230V with the higher voltage mains being...

We're going over to uPowerTek partly for that reason. Lack of supply, lack of customisation and soaring prices. uPowerTek are building custom drivers for us and offering an 8-year warranty. We've just taken delivery of a bunch of 250W drivers with IP67 waterproof onboard dimmers. We have 400W...
