You need the black light to test for E. coli. A black light looks like a black or dark purple fluorescent light bulb. You can get a small one adequate for this test right here on Amazon for about $6.00. The Chauvet Handheld Blacklight (NVF-4)

Good morning. This bacteria test kit does not NEED a black light (i.e. the lights in dance clubs, bars, haunted houses, etc. that make clothing and fluorescent colored items 'glow'). If the water sample turns color (bluish green) after the appropriate amount of time then the sample contains coliform bacteria and you will more than likely want to have the water tested by a certified water testing lab. Using the black light: If the water sample turns color (bluish green) after the appropriate amount of time and when illuminated by the black light it gives off a fluorescent glow then the sample contains, at the very least, E. Coli, a type of bacteria that causes gastrointestinal illnesses in humans and typically comes from human or animal waste. We hope this helps!

Thank you for the chance to be of service! It is a black like with the model number NVF-4 UV. Unfortunately we do not sell this item but you may can contact your local water specialist to see if they carry this item. Or, your local hardware stores. I do apologize I could not be more of an assistance. Please let us know if there is anything else we can assist you with! Thank you!

Aside from maybe putting black tape over the light, it seems there is no real solution to this problem which it equally annoying for me as well. Sorry I couldn't be more help.

It will light up when a motion detected, otherwise it's dark. If a customer want to use it as security, the light can be covered with black tape.

I'm not really sure. All I know is that when mine gets into the dark the light automatically comes on and when it's light in the room it goes off. I'm sorry for not being able to help you. You might go to a store that sells new ones that used to sell the one like you had, such as radical and maybe they could fix or recomend someone.

Eileen-Marie,I just checked ( I never noticed before - go figure) it does not light up. I guess I'm just always in the dark so it doesn't matter...

If yours isn't doing like this video at the beginning then return it. It should look like lighting in the sky quick flashes etc...Hope it helps...really is a great light!http://youtu.be/CZXFgRxgj34

On mine, red wire to + and Black wire to - you can try yours either way until it lights up. They only light up when hooked up correctly.

It looks flat black until you finish it with some clear cost and 3000 grit sand paper and then some polishing compound, check out some YouTube videos on how to black out your lights!

It's very dark. You'll love it if you prefer black. We're actually going to pick up a few more lights to add to the ones that come with it. I have a picture of it installed, but can't figure out how to get it to attach here.

You would need to buy the product which comes with batteries, it is an ultraviolet light, or have a look at this website, if that is your primary concern.http://www.blacklightshop.com/

It just depends on what you have in the room. Frustrating, I know. But you can't really "see" black light, only the things it illuminates. I would say, just go for it, or buy a nearly identical one at Walmart for $10. If it's too dark, tack a white sheet on one of the walls, and then you'll have plenty of light. You could also buy a regular black light bulb super cheap right now at almost any local store. (all on clearance post-halloween) .... Though it now occurs to me this was probably a Halloween party you were throwing... So I'll just stop talking now.

Sorry, Ryan, no clue. Is the socket making firm contact? Do you have a dimmer on that light? Beyond that....

I wish I could tell you. Bought it plugged in and no light. Spend a little more and get better quality.

Sorry dude, but lights are crap. Throw them away and bite the bullet and get streamlights or pelican

The picture and brightess seem excellent to me. In a dark room when I turn it on it seems really bright for a few seconds .??Is this backlight bleedthrough? Black seems very black. The built in speakers are not adequate and if you do any music or sound for that matter, use auxiliary speakers for sure.

I would send it back. I have had mine for some time and have had no issues with mine. Sounds like a bad light sensor. Good luck.

You have given me valuable info .Might be a reason not to but another Dorcey if there are no light replacements .Not a good sign.I will try looking into this. seaBee
