The Sekonic Illuminometer i-346 Light Meter is a small, lightweight, and easy-to-use meter for measuring light in lux or footcandles--it's an excellent choice for monitoring light levels in workplace and other environments.

The i-346 can take reflected measurements in any one of three modes: single, continuous, or delayed up to 60 seconds (when reflections from the operator may affect the measurement). The results can be displayed in lux or footcandles on the large LCD display screen. One AA battery powers the i-346 up to 20 hours. When not in use, it automatically switches off after 4 minutes. Not designed for photographic work.

If it has been over 30 days since you purchased the light meter, you would have to contact Sekonic directly.

Q: 8. This meter is used for both incident and reflected light metering purposes. I know that all handheld light meters measure incident light, but I don't understand why this meter is needed for reflected light measurements. The camera's built-in light meter is much quicker and easier to use for a reflected reading. What is the purpose of taking a reflected reading from a handheld light meter?

A: Light meters were designed long before there were meters in any cameras; since some people still like to use a hand-held meter, there was no reason to remove a capability that was already built in.

Q: 9. Can the Sekonic L-308XU accurately measure bulb flash output, e.g. press 25 bulbs?

A: The Sekonic L-308X-U Flashmate Light Meter is only capable of measuring within shutter speeds of 60 seconds to 1/8000.

Q: 10. Just got the Sekonic L-308X-U delivered. I am following the instructions to use Cordless Flash Mode. I press the Measure button and the Cordless Flash icon blinks. I am triggering a Profoto B10 from the white button on the back, aimed right at the Lumisphere. No change in F reading at all. I've tried all ISOs and shutter speeds. I have full batteries on everything. Is it faulty or am I missing something or is this not compatible with the Profoto B10?

A: When the Sekonic L-308X-U is in Cordless Flash metering mode, once you press the meter button and the flash symbol on the light meter begins to blink, you have 90 seconds to take your light meter reading. The ISO and the shutter speed should be set to the ISO/shutter speed you plan to use for your image. Instead of pressing the [TEST] button on the rear of the Profoto B10 strobe, you should trigger the flash normally by pressing the shutter button on your camera connected to a Profoto AirTTL remote trigger so the flash fires as the full preset output power, as the [TEST] button will not always fire the flash at full power. Make sure the Profoto B10 is set to [Manual] flash output, not [TTL] output, as the Sekonic L-308X U does not read TTL flash output. If you do the above and you are still having issues with your light meter, you may contact Sekonic directly by e-mailing them at support@sekonic.com or by calling them at 914-347-3302. If you feel your light meter is not working properly and it was purchased within the last 30 days, you may contact Customer Service to return the light meter for an exchange or a refund. But first, I would recommend trying the above, then contacting Sekonic for troubleshooting to ensure the light meter is working properly.
