Jradd87 Posted February 18, 2020 Share Posted February 18, 2020 Anyone have any experience with this light? I have a 9 gallon nano setup and want peoples thoughts. Positives? Drawbacks? I'm looking to do a simple setup with lamp and timer. https://www.rapidled.com/12-led-par38-bulb-actinic/ Quote Link to comment

Ratvan Posted February 18, 2020 Share Posted February 18, 2020 I think that with the 60 degree optics you should have a 12" x12" coverage, depending on how high you mount the light. 2 Quote Link to comment
Lingwendil Posted February 18, 2020 Share Posted February 18, 2020 Keep in mind that particular light is only royal blue and blue- no whites or additional colors... This may be more what you would want- https://www.amazon.com/ABI-Coral-Optimized-Spectrum-PAR38/dp/B073V5V5JP?th=1 1 Quote Link to comment

No sure if this would be a better option https://www.amazon.com/KINGBO-Aquarium-Lighting-Spectrum-Saltwater/dp/B01M0PF72P/ref=asc_df_B01M0PF72P/?tag=hyprod-20&linkCode=df0&hvadid=241976029838&hvpos=1o2&hvnetw=g&hvrand=11597980425161546563&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9012085&hvtargid=aud-801381245258:pla-400397917889&psc=1 Quote Link to comment
Clown79 Posted February 18, 2020 Share Posted February 18, 2020 I know the Abi tuna blue is an excellent par38. I've had lots of growth using it and when I have had damaged corals under it, they bounce back really quickly. Quote Link to comment

So 6" off the water with 90 degree lenses = 12" diameter of coverage. (80 degrees will be really close to that.) 60 degree lenses, on the other hand, require some math. (not going to show my work....look up an Online Triangle Calculator like me!! 😉) 60 degrees is about 30% stronger compared with the other lenses, so yield about 30% less coverage and 30% more intensity at the same mounting height. Or to look at it another way, that you'd need a 10" mounting height (about 60% higher 🤯) to get the same 12" diameter of coverage and same intensity. Roughly. What's better is only relevant to the local install....higher mounting might be better because the light can be hidden, or because it's easier to work in the tank, or...lower might be better because it's harder to see from the couch, or whatever. Maybe consider some TUNZE® LED's that are mounted inside the tank, even underwater? 1 Quote Link to comment
