LEDs – Data Collection (Part III)

CHAPTER I – INTRODUCTION

CHAPTER II – LITERATURE REVIEW

CHAPTER III – DATA COLLECTION

The primary user of this lighting system was determined to be a male of age 25-34 years located in the United States.  Figure 2 shows a sample of 112 reefkeepers, their age, and their gender.  This data was obtained from the author’s Facebook group statistics (Facebook compiled the data, and the author interpreted it.  Facebook did not sponsor, endorse, or participate in this study.)  This cross section was compared to other reefkeeping groups, and was found to be consistent.  The country of residence varied by ±0-9%, but the United States was still the predominant country of reefkeeping groups based in the United States (Figure 3).

A survey was developed and distributed across several reefkeeping online forums for LED users, including the Wasatch Marine Aquarium Society, Reef Central, and Nano-Reefs.  Approximately 85 responses were received (some were incoherent or otherwise unusable and were not counted.)  The questions were as follows:

  1. What are the dimensions of your tank (length x width x height)?
  2. How far is your fixture above the water?
  3. Are there any corals that you think were adversely affected by the LEDs?
  4. What color and quantity of LEDs do you have?  What optics are paired with them?
  5. Is your setup dimmable, and if so, what are you running?
  6. How many watts total, and how many of each size (1W, 3W, 5W, etc.)?
  7. What made you decide to go with LEDs, and if you had the chance, would you do it again?
  8. What brand of a setup are you using?
  9. Are you using the fixture for moonlights, and if so, what combination of lights/percent power?
  10. Is there any other pertinent info that might help about your setup?  Also, please leave your contact info if you wish.
