I just bought this and noticed that the RED led does not turn on unless its set to 85F isnt this supposed to turn off if the temp is set at desired

The LED should turn off when the temperature is reached. Turn the temp all the way down, then turn it all the way up. Once you pass the temp of the water it will turn the red LED on. Do you have a accurate thermometer to check your water? If it is at 85 then the unit is working. If not then you might have to return it since the calibration is off. Mine is set to 80 and it work very well.

It heats the water to the desired temp. So it turns on "red light" when the degrees of the water is lower than the desired temp. If you set to 85F it will stay on until the temp of the water is 85F. However, I noticed it heats great but doesn't decide "temps" great. So I bought a Finnex Max-300 Digital Aquarium Heater Controller and the in-line heater will only turn on when my "much improved" controller tells it too. I have my controller set to 82F and my in-line set to 85F. So if the water is 81, my controller turns on power to the in-line, the water starts heating, and once the controller gets to 82F, it shuts off power to the in-line. I did this for "fault protection". I heard this in-line malfunctioned a couple of times, got stuck to 90F and never turned off. Fried all the fish in the water... Go get the Finnex Max-300 Digital Aquarium Heater Controller, you'll thank me later!

Do you thermometer? at what temperature is your water?. Is because you have the water too hot, the heater has thermometer so it turn on when is needed.

If the light is turning red check the sensor. If ita not turning on at all, it could be a circuit issue.

I believe it's a defective LED driver or at least one of the components in that power circuit. I had similar problem with one of the 18 units after 2 months of used. I would recommend contacting the seller to see if they can send you a replacement. I plan to do the same this week. It should not happen.

If the red LED light doesn't light on the battery recharger/ receiver then I would say there is an issue with the unit or the USB port. The USB port could either, not have the correct driver installed or may need to reset. USB's can turn themselves off or trip, just like a breaker in an electrical panel, if there is some sort of an issue with a device plugged into the USB

Sorry for responding late, but I did not have the lamp at immediate reach. Now, I verified it, and you are right. Mine is not working, either. I refer to center LED labeled #58, with the tag 730, which does not turn at all when all the rest do. Somebody could say that 730 (nm, I suppose) is beyond the range of human visión, but I guess that at least a dim red light glow should be emitted. Regards. Alvaro.

I got the 2 i ordered about 5 days ago and when it charges the led light is yellow and when its down the led light completely turns off... I never seen a red led light before... You might want to search for a online manual or check your box you received it in for details

If the led isn't turning on I would try new batteries if that don't work, I would return it for a new one. Wish I was of more help, my lights worked for about 3 months and now they pi nly work sometimes. Good luck.

I am sorry it took me so long to respond, but I have been gone for a few weeks and did not remember the answers you seek. I leave the switch in the off position and when charging the red LED is on. Not sure if it goes off when it is done or not or if it changes color but I will find out in the morning.

I've never had this problem. An LED should NEVER get any more than slightly warm unless something is wrong.

Try to charge it again. The red charging light should lit. Goes off when charge completed. If the red light stay on for days that means the battery is not charging. Remember the LED lights only turn on in "DARK" when unplug from outlet or no electricity. The unit is designed for emergency usage (no electricity , total darkness). LED lights won't turn on under daylight or normal room light. Call them for replacement if you think it is defective. I have half dozen of these for three years. And they still working in good order. I hope they will last for couple more years.

I don't know exactly what the problem is but the same thing happened to me. I sent mine back to Nebo for replacement/repair which was successful. I suspect the problem is high heat generated from prolonged use causes damage to the LED, which would be a fundamental design flaw with the device. I have since tried to limit continuous on time for this reason.

It doesn't seem normal. Mine will stay a solid red and then turn off once it is charged.

Not at all should be red. I returned that light one of the fans stoped working and then I go nd out that the light wasn't even from their company just a light they bought cheap and sold high with their name on it. Return if you think somethings not right.

i did that to and decided to hold down on the on off button for a couple seconds and it lights up and starts flashing till its hot then solid light telling you what temp its on you can change temp with the minus and plus buttons hope this helps someone.

My temp lcd turns on and shows temp while water is on only. Had mine for 2 yrs now and havent had a problem. The button below my lcd never did anything - not sure if it was ever suppose to have a function.

The new model can get as hot as the old one (which I also have)...I just missing fine tuning the temp manually rather than using the LED set temps.

I'm not sure. If you have it plugged in and sitting upright, then the red light on the handle column will light up. I think I recall the directions saying something about waiting a few minutes for it to heat. If you are doing all those things & still having a problem, I'd contact the company.
