Has anyone checked the UV levels on this with a UV meter? I need levels of 2 or below with a Solarmeter for my son with xeroderma pigmentosum.

Hello, We can send you a sample of the film if you would like to conduct some tests on it.

It blocks blue light regardless of it's source, artificial or natural. And I just got my UV meters out and for instance the total UV (UVA + UVB) measured was about 1.6mW/cm^2 and UVB alone measured 113 uW/cm^2. With the glasses placed over the sensors they measure 0.00mW/cm^2 and 4uW/cm^2 respectively. The UV meter also measures 4 indoors so I think the that is a calibration issue and it is really 0 for UVB. UVB is easily blocked by plastic even if not tinted. So I would say the answer is yes, it blocks UV and blue light.

I happen to be in the lamp manufacturing business. The output of this mirror LED is in the visiable range. It has no harmful UVB or UVA component. In fact the spectral response provides excellent duplication of natural daylight.

My meter worked fine for the GU and uric acid with the old style test strips which have the blood intake at the end of the strip. However, when I used it with the new style test strips with the blood intake on the side it seems to be reading low for the uric acid test. I have not tried the new GU strips. I have tried to get the control solutions to verify the meter but no one seems to sell them. You should not need the control solutions to get readings. You do need to put the correct chip in the chip slot for what ever test you are making. If you are not getting any readings you should probably return the meter. I am also concerned it may not work correctly with the new style strips. Sincerely, Frank Huling

Hello. We have a UV lamp. Unfortunately the gel polish is too thick to spread, and is unusable. So the lamp won't make a difference. Very unhappy with our non-refundable purchase.

Mine panel reads out around 8 volts on my multimeter in the garage without direct sun. It should work fine for you. Mine has been absolutely problem free for about a year and a half now.

Klein makes quality products I've used them for many years with good results. The things I find with this meter are digital meters are hard to read in sun light and the continuity is sound and is difficult to hear even in light noise. I have an analog multi meter which I have used for 20 yrs. or more and find it a little more accurate then the digital. The batteries on the digital meter use more power and sometime the numbers fade out that's the nature of the beast. I hope this will help you

The light is UV and it seems to work well. Not recommended for daily use but once every couple of weeks for a manicure it does not seem to have any negative results.

They say uv light kills 99.99% of bacteria; period! I scan everything I have to scan; every few days!!!

Your light is not defective. I have two of these and they do the same thing. I'm pretty sure that it's either uv, or infrared.

This meter does not have that feature. It can take maximum levels, and save them but will not give you a full spectrum over a few days.

I sure don't! I bought this one and a Sun Master digital and they couldn't read further apart! What we need to find is a calibration solution that works on soil meters, not just water meters.

I grow orchids and use the light meter to monitor how much light they are getting. I do not have any experience as a photographer or in using this meter in that manner. Sorry. Dana

Mine never worked well. Used it once and threw it away. It's very cheaply made, but the light nm is not mentioned anywhere.

I just called JNH directly and asked for the EMF rating. Joyce was the ladies name I spoke to. She states that the EMF rating is 2-4mG when the sensor is 4" away! Really high. Comparably, the Rocky Mountain saunas are 0.6mG when less than one inch away. The Sunlighten is rated at 0.03mG when one inch away, FYI

I sent it back, that product sucks! I got the Lamplust solar mason jar by sunlight. It was more money but it works great and has two settings- regular yellow and RGB mode...I own 3 now.

From what I have read these meters do not accurately measure LEDs. I have LED lights and the meter reads 4500 to 7000 lumens but as you say that is a focused spectrum. My plants spend part of the day in natural light and the readings are much higher in the greenhouse.
