Digital LUX Meter

Product Code # lux_meter

This Digital Lux Meter will give you an opportunity to set up your habitat like you have never been able to do before. Until using this meter all we can do is guess at the amount of light intensity that we're supplying our animals. Unfortunately what looks like bright light to us in our living room is very poor lighting for the conditions that many of our reptiles need to stay emotionally and physically healthy.

As an example, when I take lux readings in many artificial, indoor "habitats" I seldom read over 5,000 lux directly under the bulbs that are being used. Yet at 9.30 in the morning, here in North Carolina on a clear day, we get readings of 50,000 lux outdoors in the sunlight, and we can see readings of 35,000 lux even on heavily overcast days. An average UVB fluorescent tube for reptiles produces between 500 and 650 lux at 12 inches; about the same as just before sunrise, outdoors. Our MegaRay bulbs produce between 12,000 and 18,000 Lux at 12 inches.

Please read Dr. Henry Brames' article about the importance of light to the reptile immune system.

There are three sensitivity levels on this Lux meter. You will know when it's time to go to the next level when the digital readout blanks. The sensitivity settings are x1, x10, x100. As an example, a reading of 35 on your times 100 (third) setting would be 3500 Lux.

This is an extremely simple instrument to use. Insert 9V battery into the meter, and hold out the light sensor to the source being read. Readings will be shown on the meter. While this is not a scientific instrument it is a truly valuable tool in comparing natural light conditions to those that we provide in our husbandry.
