The problem with the Bugbee trial is that they used different light sources to increase the amount of blue but those light sources also decreased the amount of Far Red. Bugbee even states that part of the decrease in yield was due to the decrease in Far Red. The 3000K white had more yield than...

I didn't think it would be this confusing! Please refer to the spectrograph in my previous post. Total Lux (lumens) at 5A = 27348lm Total PAR at 5A = 610 PPE If you multiply 27348 by 0.015 you get 410 PPE. You now have a PPE reading that is 46% less than the actual PPE output of 610 PPE. Can...

Our lights have a LUX to PPFD conversion factor of 0.022 at full power (5A). I am only stating this because if you use 0.015 you will get a 46% error. Our spectrum is not typical but it goes to show you cannot use a universal LUX to PPFD conversion unless you are using a universal spectrum. To...

Thank you very much coreywebster. I have enjoyed being here and reading your posts too. I was not an active community member before I set up the company and joined RIU but I have learned a lot from you guys. I did grow indoor plants myself a long time ago but it can be very stressful here and I...

The 660nm and 730nm Buddies were originally designed to fill the gap in typical CRI80 white LED lights that don't have a lot of deep red and almost no far red. They were designed to compliment lights like yours. But there are things you need to consider. Buddies have diffuser lenses that spread...

Hi Rocket Soul the strips are fully coated with a conformal coating which makes them very waterproof. I have a photo here somewhere to show you how waterproof they are. The reason we use liquid electrical tape on the connector wire solder joints on the strips is because the conformal coating is...

Hi everyone we will not be active on rollitup.org after January 8 as our sponsorship will expire then. This is just a courtesy thread for anyone who is running our lights and wishes to ask any pressing questions before we leave. We can still be contacted via our own website as normal. It will be...

That is just a single strip at various currents. The photo is only for reference.

The numbers are in. At about 1.05A or 50W (53W from the wall) I am getting a temperature reading of 55C at the hottest point in the middle out to 51C at each end and 53C along the edges of the 60x13 T-slot. The ambient temperature is 33C so the differential is about 22-23C. Once you build a...

Hi Rocket Soul I received some updates from Teknik today and have attached the latest goniometer reports for the strips for you to look at. The Lux to Lumen conversion is about x0.021 but it changes slightly depending on the current which affects the colour temperature a small amount. I got the...

Great looking plants mate. Yes those original High Lights were something else when Prawn first designed them. I believe most of them are still going strong.

It is not surprising that it puts out a lot of heat with a 240W driver because that is a lot of power for one board but it is perhaps closer in form factor to 2x QBs as it has 468 diodes spread across a 450mm x 300mm PCB with a 3mm flat plate heatsink. I think it should be OK as it is but...

Hi shotnva777 these types of LEDs can be confusing because you do not always get what the Chinese manufacturers say you are getting! Looking at the advertised spectrum compared to your lights I would want a proper spectograph reading see what the spectrum is really like but I will try to answer...

Got the message. Great news! Let us know if you need help with anything else.

We tried to keep the lights as close as we could and I don't think there was a 20% difference in green but you will agree that any time you compare one spectrum to the other you are going to have different spectra so that is unavoidable but thanks for pointing that out. It is the reason we do...

Hello @widowmaker31 I see some other people have addressed this post but I am not sure I understand what you are trying to say. Not all plants turn purple and in many cases it has nothing to do with the light. I'm sure you will agree that natural sunlight has plenty of UVA, UVB and blue light...

Hi @Rocket Soul it looks like the strips got to you in very good time. I hope there were no issues with customs or duties. I really look forward to seeing what you do with the strips. Thanks to you and @Prawn Connery for organising everything when all I had to do was pack and send. If you have...

Just a little plug for our Instagram "Grow-Vember" Mega-Giveaway. Only open to Aussie growers unfortunately (due to logistics of hosting with other companies), but we might open something up for international growers after November. Details here or in my sig >...

If you're an Aussie grower or smoker, you're in luck! Grow Lights Australia, AlienTech, Plant Playground and Empirical Glass – the "Best of the West (Australian companies)" – have teamed up to offer a mega-prize giveaway during "Grow-Vember" to three lucky winners. Just follow us all on...

Edit, the strip wires are 250mm and 20AWG. Sorry I should have checked the specs on our website instead of relying on my (bad) memory.
