Do you feel that 3 x Gen 4 pro is adequate for your tank? Is that a 6' long tank? Also, did you have the Photon V2 32's?

How much noise do the fans make? If I were to buy these lights, I would need eight of them to cover my tank. If they are as niosy as the Hydras, I don't think I would like listening to that noise at night
I have 3x XR15 pros over my 36x24x24 sps tank two gen 3 (WA lens) on the ends and a g4 in the middle. the two g3's were no enough imo but with the G4 in the middle there is much better coverage. The g3 are at 100% and the G4 at 70% both running SPSAB+ The tank is 2 months old so early days but things are encouraging atm with encrusting and vertical growth.
The GREAT thing about the XR15s is that the fans are off at night and very quiet when on, with one fan per puck.

I'm seriously thinking a about upgrading from gen1 to gen4. The gen1's still work wonderfully, and they are still growing corals with no problem. Compared to the gen1, do the new lenses on the gen4 reduce shadowing? Also, could I expect the gen4's to provide a shimmer that would more closely resemble metal halide than the gen1 fixtures?
I'm after reducing shadows, the metal halide type of shimmer, and a broader spectrum than my gen1 offers. I would love to stick with Radions as my experience with ecotech has been top notch products and customer service. However, I'm also considering kessil's solely for the shimmer or possible even getting a t5/mh fixture. Would the gen4's get me close to what I'm after? I know a mh/t5 fixture would be what I really need, but there are obvious drawbacks and I'd rather stick with a radion if it gets me close enough.
Also, the light is suspended over a rimless tank, so looks matter and I don't want to to a kessil's/t5 or ecotech/t5 retrofit as I feel that it would look clunky suspended in open air above my tank.

I am new to Radion with Gen4, so no experience with the prior versions, but I don't see how a lens can really improve shadowing since the light is still fundamentally a point source. I imagine the lenses improve spread, but absent a large reflector to change the origin point of the light I think shadowing is still a problem. Gen4 do have good shimmer, though not at the MH/Kessil level.

IMO the new HEI lenses seem to blend the different color LEDs and provide an overall better spread then the Gen1 but all LEDs produce shadowing, some more then others.

I'm running a pair of regular G4's over my 120 (48x30x20 LWH). For SPS, what intensity are you guys running. Right now I'm using a modifed AB program (added a bit more white) and running at 37% total intensity. That seems low to me but I've heard that much higher and I'll burn out my corals.

I am running the same program at 75% intensity with the lights 13" above the water. 37% seem low.

Get the 30s, 3 of em
In answer to your PM, I have a 7' 265. I am using three Gen4 XW30 Pro units, but I still run Kessils (3 of the 360 and 4 of the 160). The three radions replaced two Photon 32 units (V1 not V2). Were I not running the Kessils, three Radions would be insufficient. If you go with radion, I'd try three over a 6' tank first, you can always buy a fourth later. Even though ETM says 24x24 for the Gen4, and that the lenses are improved, it's still a mostly point-source light so shading will be a problem. It's a major issue with the Kessil, which is why I ended up with seven total.

Hi guys, any new report on the performance of the G4? How is it doing with SPS?
Thanks in advance

I´m running 60% (which at AB+ is 42% at peak time) and will go up to 70-75% in a few weeks. 30% IMO is too low.

Thanks. So this is without any other light supplements?

Correct. Just the G4's running AB+
