They are turn on delays (adjustable ) . They serve two purposes . The first is the obvious.To turn on each series of 3 with a delay (in case of multiple fixtures used ,so that won't be a problem with the mains fuses, from accumulated inrush current). The other purpose served is protection .The...

The HLG-120H-C1400 fits just fine 3 x BXRC-x0E10K0-D-7x. It has been already tested ,even with the COBs & heat sink at 0°C . Also the driver operates close at it's 100% load , which means also that operates at it's max efficiency. Galaξ LED grow light by Astirgrows uses 2 x HLG-120H-C1400A and...

That's the coolest rig ever ! Great job done.Love the metal-work ! Congrats !

Flashback ...Back in September 2012 . It was some months after the market release of the ASL 24 panels,by Astirgrows . Back then,some NW ,WW and monos of 645nm (all custom made for Astirgrows,by a Shenzhen-located manufacturer ), were used for the making of these panels. Recently ,A friend...

But is not at all cases ... ;-) The first( prototype ) Galaξ system is ready . http://ibb.co/h4TSOv http://ibb.co/ekdiwF The internals of the power box . http://ibb.co/mfk7Ov And while in operation . http://ibb.co/fvrgiv Cheers. :peace:

Nothing in there ... Led drivers and fans PSU ,along with Turn ON delay circuit boards are located inside the remote power box.

1 ) Die count is the same for all three types of Vero 29 .The difference is how the dies are configured . How many dies are connected in series -forming a "row " and then how many rows are connected in parallel . 2) Say we drive a Vero 29 C at ~ 79,65 Watt ... That means a Vf = 67,5 Volt and...

Well,it's going to have a toggle switch to power On /Off one of the rows of three cobs. And you haven't seen the inside of the power box,yet ... :wink: D version .The most efficient of all . ( BTW ,it seems that a lot of folks inside here think that the C version is the most efficient ... Well...

"Galaxy " . That's the new device I've designed for Astirgrows . Not completely finished yet ,but soon it will . Galaξ is a L.E.D. C.O.B. grow lighting system comprising of two units. The lighting unit (panel) and the power supply unit (power box ) . The two units are interconnected with a 3...

Currently I'm designing a new model for Astir Grows ,Hellas. It's a system consisting of a panel and a remote power supply box , with the latter containing : 2x HLG 120H-C1400A , 1x IRM-05-12 for powering the 2 Phanteks PH-F140SP fans and two "Turn On " fully adjustable delays -one per...

Interesting read ... Brother Psuagro ,you should take a peek ... https://www.led-professional.com/resources-1/articles/botanical-light-pollution-red-is-the-new-blue

" Watt" is used as a unit to measure both electric power and radiant light power ... Easy challenge ? It depends ... Whether you want to compare which fixture is more efficient at turning electricity into light , or whether you want to compare which fixture is more efficient at turning...

And somewhere here lies the enigmatic (and with plenty of irony ...sort of ...) question : How on earth it happens that a light (i.e. COB LEDs) that was not designed and made for use for horticultural purposes ,outperforms a light (Red+Blue LEDs ) which was designed and made specifically for...

The germans got " derailed " from their "rock-solid" POV ? !!! Huh ! Who would 've imagined that one ... Indeed ,Europe is changing .
