Hi — your ISH320 kit — what are the specs for this light (or a link to the specs) like par, true watts, distance to canopy etc.?

Hey @Invisible Sun LED i have a question are you guys named after the police song? Only joking :smoking:

What would be the best option to replace a 600w hps with a little less wattage and same or better yeilds.

Would the ish-320 cut it or would 2 ish 250/265s be a better option?

Hi woody. Thanks for the question. So the 320 is a direct replacement for a 600w. Yield wise our customers are averaging around 1.5 gpw but 2 gpw is not unheard of.

Everyone asks about the police song lol.

Also wondering about the difference in the lm561c and the newer lm301b diodes?

Ok so essentially the difference is efficiency. The lm301b is. More efficient chip producing slightly more light for less power. In real terms there is about 7-10% gain over the lm561c.

Our sphere tests are showing the lm301b kits @ 2.51 umols/j a gavita 1000w is around 1.90 umols/j the lm561c kits are 2.21 umols/j

Hi, I have the 265w kit but I'm in a 4 x 2 tent and would really like to take the boards off the double heatsink and buy a triple heatsink so I can space the boards a little further apart for better coverage, is this easy to do for a newb DIY'er??

Hi.

We don't stock triple heatsinks currently but you could opt for 2 single heatsinks. Would work out a bit cheaper too ??

Thanks, yeah I thought about doing that but I think I would need to either need to link the 2 heatsinks together with the meanwell driver which I don't really want to do as like it hanging at the top of the tent or I would need to build some sort of frame which would be easy enough I guess if I had the tools but I only have a few hand tools so a triple heat sink seems easiest option!
It's no big deal though as I love the light and is fine how it is, I just have OCD with stuff like this so would like the boards perfectly spaced In my tent lol
