Really though, the best Epileds come in at 220mA per 1 watt consumed... for their best, so they are better than that...

I know y'all been waiting for it... Sneak peak, exclusive peek and look...

The new 2015 A51 model.

You mean 220mW/W aka 22% efficiency? And which deep red would that be? I can't find it.

They do lol
Check this EPILEDS deep red. This is their best deep red specifically intended for plant lighting.
The specs are at @350mA and 25°C. Top bin has an amazing efficiency of 7.2%.

Not saying that Vipar uses these.

WTF....7.2% @350mA. I just received a few of those with 730 nm. With that efficiency they are just good for heating. @captainmorgan uses them also if I am not mistaken.

It makes every glow a little bit red at lights out, but that's it unfortunately. Back to the drawing board!

Thanks @Positivity. Unfortunately 8 weeks waiting time for the Osrams. That seems the only way for some acceptable efficiency I think.

-edit: I found these, will ask them if they have them on stock. It looks to me if they are the same.

I geuss if I spent 600 + dollars on less than 200 watts I'd have to jump around trashing people who are trying to grow meds on there budget too yea wat retards. Remember kids growing is all about getting good so u can talk shit lol who cares I got 2 300 w Chinese LEDs new for 130 the reason in my apartment there's no way an hid would work without cutting holes in using a ton of ventilation. No shit Area 51 optics and apache are better but until u buy it for me or pay my rent I'll grow on a budget I mean y'all are acting like u can't grow with them people use to use 1 watt panels(sucked hard) 9 band 3 w is still pretty new lol next year ur LEDs tech will b old as mine is. In so I'll have 290 real watts of led on 3 plants for 130 not a bad way to start a first grow and If u get an all red UFO for flowering to add I bet it will put out enough quality meds for me and my dad that's why we're doing this right?
