The bottom line The Extech 401025 Foot Candle/Lux Light Meter is the budget-friendly lighting meter for lighting design, OSHA compliance verification, and office lighting assessment. The 4-range automatic switching covers 0 to 50,000 lux (4,650 foot-candles), the +/- 5% accuracy meets most building inspection needs, the data hold and max/min functions enable comparative measurement, and the price is dramatically cheaper than Konica Minolta professional alternatives. The trade is the slower response time vs Konica and limited spectral correction for non-standard light sources.
