Independent testing of the ReeFi Uno LED by Dana Riddle is underway

Independent testing of the ReeFi Uno LED by Dana Riddle is underway:

ReeFi Uno

This compact LED fixture packed a whopping 72 LED diodes and 180W of max power. Using ReeFlectors to create even color blend of soft cast lighting without blinding side glare.

Other features:

  • 9 unique color LED spectrum with 9 individual channel for the most control.
  • Built-in WiFi and user configurable program schedule.
  • Continuous firmware updates to bring new features.
  • More details here.

ReeFi Uno is a game changer to continue ReeFi’s mission statement to create affordable premium LED lighting to the reefing community. ReeFi Uno is designed by reefer with microprocessor designer background and is made for reefers.

Continuing with the innovations from the ReeFi Duo Extreme, ReeFi Uno breaks the industry standard by bring premium LED reef lighting to unheard of under $2 per watt with most competition are over $4 per watt! All this and ReeFi Uno is backed with 3 years warranty!

Order cancel fees because of PayPal’s refund policy changed in mid 2019.

If you place an order and next day decide to cancel your order. please note that PayPal have changed their refund policy in 2019 such that PayPal would not refund their 3% fees. Because of this, if you need to cancel your order before order shipped, there will be PayPal fees that would not be refundable.

Thank you for understanding,

ReeFi Lab team.

ReeFi Uno sneak preview

Sneak preview of preproduction ReeFi Uno. Only thing that’s not the same as final production version is that it uses a 3D printed prototype shell while the production shell is still in the plastic injection mould tooling phase.

This little Uno with form factor of only 7.25″ x 5.68″ x 1.73″ pack a whopping 180 watts! Using latest 2 layers copper core PCB fab technology with direct contact from LED diode’s thermal pads to copper core for superior heat transfer. That along with 4 phase exchange vapor chambers are what make is possible to stay so tiny with such power. Just like the ReeFi Duo Extreme, ReeFi Uno will be backed with 3 years warranty.

More exciting specs with pricing and availability will be released Oct 9th. Pre-ordering with discounts will also be available on Oct 9th.

RMS Mount Adaptor with 3.6 degs correction option

RMS arms are known for it’s slight droop. The droop angle seems to be the same regardless if mounted with ReeFi Duo Extreme/Deluxe or Radion LEDs.

ReeFi Lab has added an option to correct for this 3.6 degs droop with using RMS Mount Adaptor for ReeFi Duo Extreme/Deluxe LEDs.

Myth about LED lighting and Lenses

There is a general believe that light from LED diodes are narrow beam and require wide angle lenses to give it wider spread. Today we’ll explore the hidden truth of LED lighting and lenses.

This is a typical LED flashlight with optical lens that you can zoom. Picture on the right is the exact LED flashlight but I removed the LED lens.

Holding the flashlight about 8″ from the door. As you can see from the below 3 pictures:

  • Optical Lens Zoomed In all the way: You get super bright narrow focused light.
  • Optical Lens Zoomed Out all the way: You get wider spread typical of wide lens.
  • No Optical Lens: LED by itself has 180-120deg spread.

Optical lens are great to focus the light to area of interest and provide brighter illumination in that localized area. However, this is not ideal in reef aquarium settings because now you get disco ball effect with different color LEDs with it’s own focused lens. The advantages of optical lenses are purely for the LED light manufacturers. Using LED lenses provide brighter illumination at deeper water penetration so less LED diodes can be used. Below are some advantages for optical lenses:

  • Less LED diodes needed to give same PAR at the bottom of the tank to lower production cost.
  • Less LED diodes means less heat generated, thus cheaper and less efficient heatsink and fan can be used to even lower production cost.
  • Less LED diodes removes the complication of metal core PCB wire routing and heat transfer, which lower the production cost even more.

Unfortunately, all these cost savings from using optical lenses do not get pass down to the consumers, but the consumers get all the disadvantages/issues:

  • Focused light from each LED diodes is like a bunch of flashlight which causes the well known Disco Ball effect. This is especially aggravated with water surface movements.
  • Create intense light to shadow contrast which is why a lot of people either switch to T5 or supplement with T5.
  • Added cost of add-on diffuser to fix the problem but sacrifice PAR performance.
  • Even with the most focused lens, if you can see the convex part of the lens, stray light will hit your eye, so shades needed to be added.

This picture illustrate stray light hitting the camera causing flares to show up in the picture. This was taken with flashlight zoomed maxed to pin point focus pointing straight up and camera is taken next to it.

ReeFi’s solution is to eliminate optical lens all together and add the following:

  • ReeFlector™: individual reflectors to provide uniform blended light without disco ball effect.
  • Custom metal core PCB with direct thermal paths technology allows for more LED diodes without sacrifice PAR performance.
  • Custom design heatsink with maximum heat transfer surface area using zipper fins technology.
  • Custom high pressure blower fan instead of cheaper lower pressure axial fan.
