Difference between AI Prime HD and non-hd?

[Coach v]

I will be purchasing a used led light for my 18 gal bow my classroom. I am leaning towards a kessil 160 or AI Prime. I see primes come in HD and non-hd versions.

I am curious what the difference is between the two?

I think the HD does ramp up and ramp down...not positive, but i'm pretty sure that's it.

HD stands for "hyper drive" .. fun huh..........
Anyways they "shift" unused amps to other colors ...........

I have the Kessil 160 and the AI Prime HD
The difference is the Kessil does not need a controller, it is very easy to tell exactly where you are at, turn the knobs for your preference. There is lots of skimmer, but I like the color blending of the AI Prime HD looks much better. The Kessil is a very wide projection of light the AI Prime is not.
The AI prime needs a controller IE has too. Using with my non updated Samsung S-3 it is a pain in the butt to program, I really do not know where I am with this light, yeah I am not tech savvy, I've had it at 100% over a QT and caused a massive algae bloom so bad it killed the Aptisa LOL.

Get the HD model if you do because you can copy the AB+ exactly and that is a proven spectrum that works.

Hi there,
Can I jump in with additional questions please.
1. I have several Prime lights but dont know how to tell if they are the HD version or not. Does anyone know?
2. BlueSpot; when you refer to the AB+, I guess you are talking about a downloadable preset? Where is it available and would it suit Hydra 26's for an RS650Max?
Thanks
Scott

A Prime HD will give you the ability to go over 100% intensity on any given LED spectrum, a non HD will not. If you go into settings and adjust your lighting if any of the bars Will go over 100% if the others are less than 100% than you have an HD model.

thanks Josh. Just be sure as your 2 comments seem to contradict each other.
If the bars go above 100% its a hd, if they only go to 100% they are not a hd?

That's correct, here's a picture of my HD model, as you can see my violet spectrum is set to 116% this is not something you can do with the non HD version. Oh and to clarify what I had said earlier, in order to go over 100% with the HD model on certain LEDS you need to go less than 100% with another LED.

Apologies for jumping on this post but my prime goes over 100% so as you say it’s a HD model. Only thing is I don’t get the extra violet/purple colours leading me to wonder have I purchased the freshwater model? Will this still be ok for my corals?

Hi everyone I just got into this discussion with a friend and if you look under the light where the serial number is you will fine that the HD ones have HD and the none HD won’t
