After turning on the UV light, I see the light color is white, not purple color at all, that normal?

UV light ranges in wavelength from about 250 nm to 400 nm, that said only the wavelength closer to 400 nm is purple, dont confuse this with the more familiar black light bulbs, which only go down to 450 nm and appear purple. in order to sterilize the water the UV must be at or below 350 nm which is below the limit humans can see, so what you are seeing is the glow of the gas in the bulb which appears whitish with a blue haze, This means the bulb is designed to act as a stetilizer and not to make your old black velvet 70 s Era posters glow all groovy.... also the invisible UV can cause a sunburn on your cornea so limit any exposure, this effect isnt instant it takes time and causes eye itch...

This is normal. If the light is out so is your UV lamp. By the way. I have that same filter on my 30 monster Oscar Cichlids tank I have not change the water or clean the filter for 9 months. The numbers are great. Excellent filter for the price. Make sure you put some good bio rocks, carbon and ammonia media. Good luck

I had the same problem. The safty switch inside is bad. You have to turn off filter, open it up and I put a small ball of aluminum foil in hole to hold the safty switch on. Re assemble and only use the manual switch on the outside.

Yes this is normal, it will have a white-blue tint similar to those LED bulbs you see on some cars. As long as its lit up through the little peep hole you're good.

I have two Sunsun filters. In order to see any color (and it is very faint blue) you must get your eye directly over the top of the small lens. Don't stare for long. UV can cause eye damage. The fact that you see any light tells you that the bulb is lit. Don't run it continuously. Only when you seem to have a clarity problem. Otherwise, you are wasting the life of the bulb. Also, do not turn on the light when you are cycling the tank. It will kill the nitrifying bacteria in the water column. This permits it to be seeded on various surfaces in your tank including your filter media, gravel, rocks, etc. I have two Sunsun filters.

That can be subjective but what I can say is its not the warm orange or yellow of say an incandescent light. To me is a brighter white with maybe a hint of blue making the light seem grey?hope that helps

Led I don't know but it works with UV light...I don't know the difference between the two

It doesn't say anything about UV on the package. The graph shows little output below 400nm, <5% daylight. It's equivalent to a 10w fluorescent and a 50w incandescent.

Its is not a bright white light if that is what you are after. It casts a soft yellow light.

There is a sealed on/off switch on the top of the unit for the U/V. just turn it on. You will know if it is working as a small LED light by the switch will illuminate.

Dear friend, yes. Below the clear cap between the prime button and the hoses you´ll find the UV switch, take this clear cap off and you can turn the UV on (blue light on) or off (blue light off)

Yes I think so , not sure if my tech uses a uv or led light. But I think so. Sorry hope info helps.

Yes I can see the UV light . My room is 13' x 15'. I turn the UV light off at night

I believe that what you received may, in fact, be a different device. There are two types of gas used commonly, with very slight differences in the frequency and power output. Violet is the preferred, due to less UV output.

I have not seen purple color, but the light is amazing! I have a plasma tank that hangs on the wall and the light is perfect size for that! I used "Power Grow" setting and my corals were ready to jump out of the tank! Excellent light, highly recommend!

Unknown. Because the UV is a feature that you can turn off or on, you don't have to use it. The unit itself does a very good job without the UV. You could try calling the manufacturer-their website doesn't mention the type of UV light, but customer service might.

Mine too. Given the language issues in the user manual... I'm sure this is just a firmware variation. I also noticed that the menu says infrared LED, while the LED on my unit is visibly white.

Hello, I bought two of these units. They work great but the light is a little bright while sleeping. Fortunately there is a button on the top of the unit that turns the UV light off. Hope this was helpful.

I would take out the filters from behind the UV lamp and then put the back on the unit. When you turn on the unit the UV violet color should show through the back fins of the case. If not then your UV light could be not working.

Hody , I use mine indoors so I don`t have any experience with UV ... it is a bright yellow , so better in the sun than black or grey chords . I love my US Wire product !

I dont recall because I replaced the bulbs with LED lights. the lights that came with the lamp made the shade appear purple. the natural white led lights makes the shade appear as black
