Review on 🐠 hygger Aquarium Programmable LED Light: Full Spectrum Plant Fish Tank Light with LCD Display and 7 Colors for Novices and Advanced Players by Rachel Simmons

I have to say that for a planted freshwater aquarium or just an aquarium, this light is incredible, especially considering the cost. I have tried many lights and this gives the best colored light to keep the fish looking good and the right spectrum for the plants to thrive. Yes, figuring out custom programming is a little tricky, but once you get the hang of it, it's not that hard with the light in front of you. To help others, here are some tips: DO NOT PLAY WITH THE LIGHT AT ALL WHEN IT IS IN USER MODE! If you do anything with the light at all, the user program will not start again until the next day or until you enter the user time setup menu again. For example, if the light is running on a custom schedule and you change the color of the light to red, the light will no longer follow the custom schedule for the rest of the day. You must either re-enter the custom time setting or wait until the next day for the custom schedule to be applied again. In user programming mode you have to set so many times that I find it useful to write down all the times and light levels. for each "Lx" value before I start programming. After a very short period of time with no button presses on the lantern, the light will automatically exit the custom setting mode, so speed and efficiency are a clutch. - Only the blue color "moonlight" is supported in user mode. So don't waste your time changing the color of the moon in custom mode like I did. You can adjust the moonlight intensity in custom mode. In modified default mode, the opposite is true; You can change the color of the moon, but this is only supported at 100% intensity. Don't expect the intensity of the light to change at the precise moment of programming. I find it takes 15 minutes to reach the desired light level in the first and last parts of the daylight cycle and five minutes to switch between the rest of the daylight mode settings. That is, if you program the light to turn on at 9:00 a.m. at an intensity of 40%, the light will be very low at 9:00 a.m. and slowly increase in intensity to the programmed 40% over 15 minutes . Great feature, but confusing when you're not expecting it. If you program the lighting to go from 40% at 9:00 a.m. to 70% at 10:00 a.m., the light will not reach 70% intensity by 10:05 a.m. Set the programmed intensity. It takes 15 minutes to slowly adjust the lighting to the time you program. It's confusing if you don't expect this behavior, but it's a nice feature. I recommend using the 24-hour time format. This makes it easier to program. - Here is an example program for user mode and how I pre-write it so as not to get confused while programming. I also usually draw a chart with the time written on it: *Remember that L1 is the only "L" value that requires both an on-time and an off-time. * All other "L" values use the previous turn-off time L like the on-time one. time, so just set the timeout for all subsequent "L" values. 00L7 20% 23:00L8 0% 2:00 This program does the following:- L1 At 7:00 the full spectrum light dims and then ramps up to 30% intensity for the first 15 minutes and then stays at 30% at 8:00.- L2 At 8:00 the light takes five minutes to go from 30% to 60% and then stays at 60% until 9:00.- L3 At 9:00 the light takes five minutes. minutes to increase the intensity from 60% to 100% and then stay at 100% until 19:00 (19:00).- L4 At 19:00 (19:00) it takes five minutes for the light decreases from 100% and then stays at 60% until 20:00 (20:00).- L5 At 20:00 (20:00) the light lasts five minutes to decrease in intensity from 60% and then to 30% to stay until 21:45 (9:45 p.m.).- L6 At 9:45 a.m. (9:45 p.m.), the light takes 15 minutes to slowly turn off the full spectrum and turn off completely. turns off at 22:00 (22:00).- L7 At 23:00 (21:00), the light takes 15 minutes to slowly turn on the blue light until its intensity reaches 20% and it stays there until 1 :45 . - L8 At 1:45, the blue light takes 15 minutes to slowly fade completely at 2:00. - The light stays off from 2:00 a.m. to 7:00 a.m. the next day and starts the cycle again. Hope that helps. others, and I hope I understood everything correctly. It really took me a while to try to type this in a meaningful way! I also built a custom 1x pine canopy to elevate the light above the aquarium for better light diffusion, flicker, easier aquarium maintenance, and protection from water and condensation.
