I have been reefing since '98 and have witnessed many improvements and trends. I am not prone to taking risks with my progressive reef. So it is no surprise that it has taken me two years to decide on the light upgrade for my dense mixed reef.
I required: >150par @ 48", >100*optics, 395nmUV, whisper quiet, simple UI, component repairable, remote IP accessible, and Budget Friendly.
Daniel Lu presented a live demo of ReeFi lamps whereby, meeting all my requirements. In addition, he implemented further improvements of the UI including noise reduction. I can say these are light weight and reasonably quiet.
There are 6 over my 250DD 60"x36x27 for extreme coverage. I find them very powerful and deep penetrating shimmer. Wide 4" crossbar? No cast shadow when positioned properly. I have them mounted in a elevating canopy 18" above glass tops. I chose the Reefi to replace my 4 Helios 180w+t5. Excellent customer service, even video-chat of set up too. 36"x36" coverage is fantastic, similar to 150w light cannons. Im loving the customizable channels that include the 395UV. Its the one spectrum missing in most sets with the exception of 400w halides, at this intensity and gets SPS to regain the sunbeam fluorescing I lost 4yrs ago when I removed my Radiums. I have been increasing my perimeter Reefi power to 50% and lowering the center lamps to 40%, due to a LPS maze brain top burn that is 14" deep on the reef. All others are having daytime PE and measurable growth within the 3weeks ReeFi has been running. And as advertised, the lamps quickly recovered their sync several times during storm power-loss. Firmware wireless updates are easiest yet compared to other brands, just select IP lamp and update. I love the temporary set feature for trying new looks and showing off these settings that revert after 30min to resume schedule. Or "apply" to keep new setting. Simple UI select and drag, no laborious written code sequences. Any mobile wifi device can sync to the IP Reefi, alike high end DSLRs. Just, well thought out conveniences by a Programmer turned Reef Aficionado. I look forward to replacing my FOWLER black boxes shortly.
