A light meter is a tool that many photographers can't live without. The right meter can help you determine the amount of natural light for a photo so that you can adjust as needed and change the shutter speed for the best photo possible. When you're shopping for an ambient light meter, it's important to look at each one individually and compare their specs and price with others on the market.

Not all light meters are alike. Some are for very specific jobs, so it's important to find one that's designed for your particular needs and industry. You may come across light meters like:

1. Video light meter

2. Ambient light meter

3. Digital light meter

4. Portable light meter

5. Photography light meter

Get the right kind of light meter for the task at hand

A photographer's light meter for determining shutter speed is very different from one that growers use to ensure proper light levels in a greenhouse, so take care to pick the right model for your needs. Look at the meter's sensitivity and accuracy, and the software that comes with the device. Also consider the size and warranty. Some meters have extras like wireless capabilities and programmable options, which are nice to have if you're going to be out in the field.

I recommend: Shop smart and know what you're purchasing. Companies like Sekonic Light Meters and B&H have great e-commerce websites that sell different types of light meters to different industries, so you can get a good idea of the type of features that various models offer.

Compare the specs on each digital light meter to make sure you get the best product

Once you have a few models in mind, dig deeper and compare the specifications. Pay attention to things like range and resolution, for starters. On the high end are light meters that go to 400,000 Lux, while on the low end you'll find up to 20,000 Lux. Some models can create charts and graphs and store data for future use. Others can even test the air for moisture and wind that could affect your photos-- or plants.

I recommend: Compare several different models. Technika's website has a handy chart available that really puts the different digital light meters into perspective. Extech Instruments' site is a bit harder to navigate, but it has a wealth of products and information that make it worth the time to research.

Save money on industrial light meters by buying in bulk

A good light meter may set you back a few hundred to a few thousand dollars, but if you have to buy more than one, you may be able to get a price break. Many vendors now offer discounts on second and third meters, so always ask about discounts if you're buying more than one unit at a time.

I recommend: Buy in bulk and save. D.A.S. Distribution and Professional Equipment both have prices listed for single units as well as bulk purchases, so you know right away what sort of deal you're getting. If you plan on buying more than a few, call to see if they can give you an even better price.
