Question: Hi, what is the % of accuracy for this device and does it measure accurately at less than 40 foot candles?
Document: If your looking for an inexpensive light meter that can measure foot lumens accurately, this is for you. It is built well and I use it every day for commercial use, it hasn't let me down yet. 5 Stars!! !
Really like the meter for the price. I have no idea how accurate it is, don't really have an easy way to test that. I do like that it came in a padded plastic case which stores the unit. It also measure both lux and foot candles. I am using it to measure the brightness of my front projector and for that it works great.
I use this to read light levels in Lux or foot-candles on work surfaces. Once i have the reading i know if the area is adequate for the task to be done in that location. If not i can calculate the amount of lumens needed to give the correct lighting level.
Works as advertised. Small discrepancy though. The listing stated it was able to measure candles but this is not the same term used to measure light. It does measure candles but that is not the term used on the keys.
Excellent Lux and Foot-candle meter for the price. Great for using as a tool to measure for building codes and relative lighting abilities.
The product does what is says and is easy to use. I use it to measure the lighting levels in my mechanical workshops, reception areas etc. I cannot comment on pinpoint accuracy but it does what i need it to do.
The package arrived in a a timely manner but the meter was DOA and when I checked the instructions they said to slide off the battery cover and replace the 9-volt battery when it ran low, however there is no battery cover. No replaceable battery means this is a junk product. Also, if you need this to measure wavelengths somewhat beyond human perception this isn't going to work for you, as someone else pointed out this measures in Lux, to measure more accurately get a radiometric light meter.
Used to create product specifications on our eCommerce site, it reads light accurately and is easy to use with a long battery life.
Novice photographer this device has no instructions on how and when to use it! If you are a beginner buy a couple booms first, or take a class!! Overall quality of the device seems good.
It's a great product for accuracy. The only thing I didn't like was you can change the light reading based upon your position of the sensor to the light. We use this in a theatrical setting, so it makes it more difficult to determine the accurate footcandle.
Answer: I have the Model LX1330B.  The specifications in the instruction manual reflect the following:Light-measuring level from .1Lux to 200,000LuxAccuracy +- (3%rdg+10dgt) <=20,000Lux/2,000FC+- (5%rdg+10dgt) >= 20,000Lux/2,000FCRepeatability +-2%Photo detector lead length ~150cmSpectral Sensitivity- curve shows mostly betweeen 500nm and 650nmThe specifications page does not directly relate to foot candles, but hope this helps.
