The AH-300 stands out for its wide LUX range and specific spectrum functions: it reads as low as 2 lux up to 180,000 lux, reports CCT, and shows the white LED spectrum generated by a 450nm chip with phosphor luminescence. The bottom line: it is a practical, app-enabled meter for anyone needing reliable LUX distribution and blue light irradiance data, especially when working with 450nm-excited white LEDs.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide LUX range:\u003c\/strong\u003e Measures from 2 lux to 180,000 lux so it covers low ambient to very bright lighting environments accurately.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCCT measurement:\u003c\/strong\u003e Reports Correlated Color Temperature to help match and tune lighting for photography, displays, or horticulture setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpectrum display for 450nm LEDs:\u003c\/strong\u003e Shows the light spectrum for white LEDs driven by a 450nm chip, useful for understanding phosphor-emitted peaks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlue light irradiance:\u003c\/strong\u003e Tests blue light intensity and percentage, reporting w\/m2 to help assess eye safety and sleep-impacting exposure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLUX distribution and CSV export:\u003c\/strong\u003e Records distribution maps and exports the data as a CSV file for further analysis or lighting design reports.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple mobile app:\u003c\/strong\u003e A three-step, secure app workflow makes testing straightforward and the data easy to access on a phone.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe AH-300 is ideal for lighting technicians, indoor growers using white LEDs, designers and photographers who need accurate LUX and CCT readings and want to record distribution patterns.
