Re: What do you run in your 4x4?
I will elaborate a little on why I do not like Chinese knock offs. 1st. reason, they all claim to use Samsung top bin LEDs, HLG I believe would purchase all the top bins from Samsung so there would not be any left over for the Chinese companies. 2nd. Pricing drops with LEDs when you are happy to pu...

Re: Is there an inexpensive light intensity or par meter?
Just how linear the curve was and parallel to the par map is extraordinary I never expected them to be that close. Certainly with white led. Shame he hasn't tried with several phones yet. But very promising results from the s8 certainly. My Nexus 5X, XZ1C, and now-long-gone Nook (don't have model h...

We do tend to be at least a year or so behind the usa in the UK but with the extra taxes and shipping fees and dollar conversion all latest tech i...

Re: I need some driver help...4x qb288 v2
JGG, That model isn't a programmable driver. The "EUD" series are the programmable ones. And the only one I can "readily" get is the EUD-600S280DT (not sure if DTA or DTL yet). It's a constant current driver. Output Current: 2240 - 2800mA (programmable via pc). Output Voltage: 108 - 268V So that ou...

Re: Samsung L2 Horticulture Strips
I'm running some tests on the latest hlg uv supplement board. And I can confirm eye protection is ESSENTIAL. I actually scared myself somewhat after 10 minutes with still little bright yellow and violet dots in my vision after only brief exposure and that was at only half power. Do be careful people.
