Do you have to wear safety glasses when using uv lights? Seems like some come with yellow glasses, is that needed to protect your eyes from uv lights? If so, does the dark filter that’s on this light mean you don’t have to wear safety glasses?
@@H750S you must wear safety glasses. You cannot see UV light It is invisible to the human eye . That black filter you see on the front of the flashlight is out all the unnecessary visible light spectrum that we see as a purpleish light . The purple light we see with her eyes does nothing to make the fluorescent glow . It just allows the user to see where the light is pointed.. So you have the pure UV spectrum of 365 enhanced and really strong without any visible light with very little visible light cast on the area that you’re looking at .
Is Mrs. air conditioning on ? or just air conditioning off? You cannot have air in the system if you use the vacuum pump properly If you recharge it by using the sticker under the hood, that tells you at what weight of refrigerant you add by ounces or grams your high side pressure should not be too high What is the ambient temperature? What is the temperature coming out of your dash? What is the low side pressure? What is the high side pressure? What is the temperature of the line going into the condenser ? What is the temperature of the line coming out of the condenser? Was any kind of work done around the engine that could’ve possibly disconnected the coolant temperature sensor ?
Bought because you recommended it , after years of trial and error , big thank you !
I got the black smaller one that takes a 18650 battery. Said it had the best wavelength bulb at the time
Still 100 times better the what you buy at the auto parts store

@@coldfinger459sub0 good to know thanks man. So just the regular clear safety glasses or do they have to be yellow/orange?
@@H750S yellow or orange.
The clear only stop a small amount of a certain band wavelength of UV .
@@coldfinger459sub0 got it, thank ya sir👍🏻
For diamonds search which is best
Please reply, long range
