The ETI 1301 is an economical
light tester ideal for both the professional and hobbyist.
The ETI 1301 allows the user to monitor light intensity and
levels in a wide variety of applications. The best way to
use a tester is to measure the light levels when installing
new lamps or lighting and then measure the light intensity
thereafter on a regular basis (monthly or quarterly) until
the lamps require replacing.
The ETI 1301 measures both lux or foot-candles over the
range of 0 to 50,000 lux/foot candles. The unit is powered
by a 12 volt MN21 alkaline battery.

The correct level of light is a necessity for plant growth.
Sufficient light is needed for photosynthesis to take place
so plants can flower or bare fruit. Commercially, it is
important to regularly check artificial lighting levels to
ensure healthy plant growth. The lack of adequate light is
the most common cause for poor plant growth. As artificial
lighting will degrade in intensity with time, it is
essential to measure at regular intervals.
