Is it necessary to have an led dedicated lux meter in order to obtain accurate readings of led lighting systems?

The technical answer to your question is yes. LED light is very different from incandescent light. The Illumination Engineering society has NOT changed the way they measure light in 50-6- years, they are working on it. We always use a regular light meter only because there is no other real way without spending a fortune. There are technically many things to consider and they way we precieve light is very different with LEDs. What we look to many times is the manufacturer's info on lumens the fixture produces. Good luck, PS, we got a wide range of DIFFERENT READINGS FORM THE aMPROBE METERS WE BOUGHT SO WE DO NOT USE THEM AS WE NEVER KNOW IF THEY ARE CORRECT OR NOT.

does it also measure foot candels for LED lighting sorces?

YES IT CAN MEASURELM-100Light MeterThe Amprobe LM-100 light meter measures the visible lightfrom fluorescent, metal halide, high-pressure sodium orincandescent sources. It is a portable, easy-to-use digital lightmeter designed for simple one-hand operation reading inLumen (lux) or footcandle (fc) units. The LM-100 measures awide range of light up to 20,000 fc or lux with an accurate,high resolution of 0.01 fc/lux.Use the LM-100 light meter to measure the illumination levelin the interior and to switch off or reduce or increase theoutput level of lighting fixtures. Reduce the energy burdenof the building by significantly increasing the efficiency of itslighting system.One lux is the illumination from a one candela lampperpendicular to a surface one meter squared at a distance ofone meter. One fc is the illumination from a one candela lampperpendicular to a surface one foot squared at a distanceof one foot. 1 footcandle = 10.764 lux and 1 lux = 0.09290footcandles■ Measure in Lux or Footcandles, front panel switchable■ Measuring Range to 200000 Lux or 20000 Foot candles■ Silicon photodiode sensor and filter■ Data Hold to freeze reading on the digital display■ MAX ability to show high readings■ Includes protective sensor cap

Do this light meter measure HPS grow light

The meter's specifications are designed around incandescent light measurements with a filter for white LED lighting. You can measure other sources, but the results would only be useful comparing bulbs of a similar type.
