I have done a lot of reading on this forum of LEDs burning out corals, and making sure the intensity is correct. Does anyone have any experience with the 240 pros? Anyone running a program and having success? Care to share the program? Thanks!
OK, a while back I saved a Excel spreadsheet/program that someone created (Ben Nichols on RC...Thank You!) to calculate intensity settings for another light. He used the SIN curve which the sun roughly follows. Originally the program did one hour intervals and 30 minute intervals over a 12 hour period. I used his work to add further options. I tweaked it to calculate 30 minute and 10 minute intervals over 12 hour, 10 hour, and 8 hour light cycles. The 10 hour and 8 hour cycles take the SIN curve of a 12 hour cycle and condenses it into the 10 or 8 hour timeframe.
To use it:
1. Download the this Excel document(Rt click save then open in Excel): https://www.dropbox.com/s/t8spfthlab7suzj/Lumentek Intensity Program.xlsx
2. Select the desired interval and timeframe from the sheets at the bottom
3. Enter your desired start time (the program starts at 0 so the lights will come on either 10 or 30 minutes after your entered start time ex. if you want your lights to come on at 10:00am enter 9:50am or 9:30am as your start time)
4. Enter your desired maximum intensity for Blues and White/Color
5. The fields and chart should automatically update showing the proper intensity settings
EllisJuan - thank you for the link .. I figured out how to get it to open correctly. It is the same as what I was looking at before. So now just to figure out the best max intensity still and ratio of whites-blues. Any thoughts?
Well I have officially had my new 240 pro running for a day now. I love the programmability, and the light looks great! I also received my fuge light today! Thank you Rick for the wonderful products. I have been running it at 50% max at mid day and ramping up and down through morning and evening, thanks to the help of EllisJuan's spreadsheet he provided. I hope to figure out the best ratio of blues to whites for coral growth.
