We've got the Samsung strips up here: https://growlightsaustralia.com/product-category/diy-led-grow-lights/strips/ Prices include GST and there are bulk discounts. We're working on geting some extrusions made locally with the Samsung F-Series screw pattern that can be sold as DIY kits for those...

OK mate, I'm sorry it has taken so long, but the website has been updated with the new PAR maps here: https://growlightsaustralia.com/420-par-maps/ Imust say i was pretty surprised when I upploaded ther IES files to create these PAR maps as the new High Light 420 boards are significantly more...

We have lots of Samsung strips in stock (care of @Prawn Connery ) but I haven't put them up on the website yet. I hope we didn't give you the wrong impression. At some point we may produce our own strips, but not for a while. I will try to get the Sammies up next week. They will be cheap. Not...

Well that's because it wasn't your fauit. The problem was with our card payment processor who incorrectly flagged your transaction – we're now looking for a new payment processor :roll: (In case ayone is wondering, that is why we don't have a credit card facility at the moment, but we're working...

LED Teknik has tested quite a few Nichia and Samsung diodes over the years and found that Nichia LEDs usually match or slightly exceed advertised specs, whilst Samsung advertised specs are a bit more optimistic. Everything depends on available bins, but the top Nichia bins are the most efficient...

UVA and near-UV (400-420nm) does increase cannabinoids and terpenes when run full cycle (12/12) and this has been proven in scientific studies. We've also done our own testing which confirms the results (and we continue to test). It's the reason we include UVA in our own LED boards, as it does...

Mate, if something works it works. We appreciate the feedback.

Tell us about it! We're also very much hindered in Australia, but we try.

You're not going to get an accurate reading for a UVA light with a LUX meter as LUX meters are weighted towards the green spectrum and measure brightness in relation to the human eye. I couldn't find the lights you describe on Google. It would be helpful to know a bit more about them, such as...

Hope I'm not too late to the party. We have a second test grow underway at the moment with the new boards vs old. The first grow produced 1410g inside a 4.5'x4.5' under 4x High Red + UVB Reptile bulbs (left) and 4x High LIght 420 boards, both connected to 480 drivers pulling about 470W each. So...

We haven't had any additional stretch reported with the new boards and they have twice as much far red – over 9%. What is sometimes forgotten is blue light and UV also counter shade-avoidance, so it is not just R:FR that regulates it. Our original High Light UV boards have almost 5% far red and...

It's certainly possible, but it comes down to how much people want to pay for such systems. At least they will get cheaper as the technology develops. We're really only just starting out wth LEDs as far as horticulture is concerned.

He's pairing the single boards with 240 drivers and the double kits are just 2x single kits, again with separate 240 drivers. DIYLEDUK normally uses XLG drivers set to the maximum board current (5A) with a little "Void if removed" sticker on the driver adjustment. He also uses external dimmers...

I can't edit my original post now so I need to point out that Valoya calculates its R:FR and B:G ratios using the Sellaro method and that the published figures are indeed correct and my asumptions were wrong. https://www.valoya.com/wp-content/uploads/2019/06/Lighting-Guide-2019.1.pdf

I think it also might be worth mentioning that Far Red really does reduce flowering times and so this might also have an impact on cannabinoid levels at the end of the grow. Especially when comparing the same strains. It wuold be interesting to know if Valoya took this into account. Here is what...

I watched the webinar and I also did a little bit of research afterwards. We need to clarify that Valoya did not test THC levels in the UV vs Far Red experiments – only CBD. Perhaps their THC results were not what they had hoped for. I would expect that if they were, they would have published...

Thanks for the link mate. I'll have a look.

No I haven't seen that presentation. We've done some THC testing ourselves and have seen increases with the addition of near-UV (400-420nm) in our original boards, and they already have almost 5% Far Red – which is much higher than most other white phosphor-based LED grow lights. The new High...

DIYLEDUK is our distributor in the UK and Europe: https://diyleduk.com/collections/high-light-diy-led-board-kits @Frank Cannon has just completed a full grow of the new High Light 420 bords vs the old High Red boards with supplemental UVB (6% Arcadia reptile bulbs). As mentioned, the High Light...

Hey mate, all good. Our website has a geolocator for pricing in either AUD (if you browse from Australia or New Zealand) or USD (everywhere else) which can be thrown off by using a VPN. Regardless, it should say what currency you are looking at and you are also able to chage currencies using the...
