Will it properly detect Yooperlites? I was told you needed at 365nm and not sure difference between that and this.

Fluorescent minerals emit visible light when exposed to ultraviolet light, this is called "excitation". Each fluorescent substance has their own optimum of their excitation and emission light wavelengths (sometime several) - the closer to the optimum UV light you use to highlight such substance the more bright it will light. The yooperlite it's a form of a mineral sodalite, the excitation and emission sodalite spectra you can easily google (e.g. here: nightsea c o m_nature_minerals_sodalite-fluorescence, substitute underlines with a slash). As you can see the excitation optimum wavelength for sodalite/yooperlite is ~385 nm, and the emission optimum is close to 630 nm - and the stone shines between orange (600-630 nm) and a red (630-700 nm) lights, with high emission at the red part. So the answer: this lighter is ideal for yooperlite detection, and the 385 nm UV light suits better for this purpose than the 365 nm light though the latter also can make the stone shine, but almost 1.5 times weaker.

What is the up beast for and what can it do

It is very useful for detecting contamination in motel rooms like feces, urine, rodent droppings and urine, insects like scorpions. Fungus and other plant materials indoors and out will show up well especially if you use it in the dark. Detergent residue glows bright. Teeth really light up if you use almost any toothpaste.

Does the indicator on the charger light up solid green or flickering green when ready? I can't tell since the charger already was green before

Hi. When the batteries are inserted into the charger, the charger will determine the need for charging the batteries to 4.2 volts. If so, the charger lights will turn red. Then when charging is complete the charge lights will turn green. Hope that answers, but otherwise if you require any further assistance please email our support on support@uvbeast.com. Thank you.
