{"product_id":"spectral-illuminance-meter-ls335","title":"Spectral Illuminance Meter LS335 with Touchscreen and PPFD","description":"\u003cp\u003eThe Linshang LS335 spectral illuminance meter measures light level and spectral characteristics for lighting fixtures, indoor spaces, outdoor installations and plant-growing setups. It covers 0–1,000,000 lux and displays correlated color temperature, color rendering index, flicker information and a spectral curve. A separate cabled probe allows the sensor to be placed at the test point while the 3.5-inch touchscreen remains easy to read.\u003c\/p\u003e\u003cfigure\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0273\/2133\/5851\/files\/spectral-illuminance-meter-ls335-touchscreen-control.jpg?v=1793772370\" alt=\"LS335 3.5-inch touchscreen control during light measurement\" width=\"990\" height=\"758\" loading=\"lazy\" style=\"max-width:100%;height:auto;\"\u003e\u003cfigcaption\u003eLS335 3.5-inch touchscreen control during light measurement\u003c\/figcaption\u003e\u003c\/figure\u003e\u003ch3\u003eCompare lighting and spectral data\u003c\/h3\u003e\u003cp\u003eThe spectral sensor measures 400–700nm at 10nm intervals and calculates illuminance with photopic weighting. Lux and foot-candle units are selectable. CCT, CRI and spectral views help compare light sources, while flicker frequency and depth describe temporal variation. UV index, temperature, humidity and a blue-light-ratio parameter provide additional displayed information.\u003c\/p\u003e\u003cp\u003eReal-time, maximum, minimum and average light-level readings support comparisons over an inspection period.
