Adjusta-Watt Retro 720w LED Grow Light

Physical measurement is 90 x 90cm so great for filling those gaps! This LED is ridiculously cheap - don't delay and make the switch away from the hot HPS lamps ! Now comes with an optional controllable ballast that uses a PWM RJ14 connection - this means, it is physically able to connect to external controllers (with the right adapters) like Trolmaster, AC Infinity and Telos Grow Cast - whether the software is compatible is being confirmed! 

LEDs driven by a HPS ballast is a popular option right now and are a great "bridge LED" for those looking to move away from HPS and are on a budget.  We've tested these LEDs with an Apogee PAR meter, and the PPFD outputs are around 1000-1200 PPFD across the canopy from 12" which is amazing! 

However, be mindful that the cheaper LEDs may seem...they will come at a cost; usually less efficient (watts input to PPFD output), run hotter, and the diodes will deteriorate quicker (less PPFD output over time). 

To illustrate efficiency using an example, a DIMLUX 500w Xtreme led on only 55% will give just as much light PPFD output than these 720w HPS ballast LEDs at 100%...but obviously, you are paying more than double for that Dimlux!   

So in summary, if you want to move to LED away from the hot HPS, and don't want to break the bank in the short term, then these HPS-driven LEDs are a great option. An analogy we use in-store, it's the difference between getting a run-around motor versus an Audi R8; Lynx Africa versus Paco Rabanne; Elizabeth Duke versus Tiffany; Casio v Rolex.  You get my drift.
