What's the minimum lumen output of BR30 bulb when using a mains dimmer?


For the BR30 bulbs, when using a mains dimmer like the Lutron Maestro LED+, what's the minimum lumen output from a bulb at the "on the threshold"? Those dimmers have an adjuster to fine-tune the minimum output from the dimmer to feed the bulbs the lowest voltage that will get them to turn on.

For the 5-spec LED strip, when using the Film-grade DMX 50-channel dimmer (3082, 24V), I've noticed that at values <2% (either via manually setting it to 2%, or a value of ~5 via DMX), the LEDs won't turn on (I've been using the 30KHz PWM, but haven't tried lower values). With the LED strips, I'm trying to create cove lighting that can vary from very low levels to very bright. Do you have any recommendations on how to get a lower minimum output from the LEDs?

The minimum dimming level is 20% for the BR30 lamps. Therefore we would expect that the minimum lumen output would be approximately 160 lumens. We have not tested the Lutron Maestro product and are unsure about the dimming trim and whether this would improve the minimum dimming level. You are more than welcome to take advantage of our 30-day free returns policy to test this empirically and determine if this lamp would be suitable for your needs.

​For the PN 3082 DMX decoder, we would recommend adjusting the gamma value. The gamma value will essentially provide you with a steeper or shallower dimming curve, allowing you to adjust the brightness at a rate that better suits your needs (we suspect you will want a value > 1.0). Additionally, we would recommend checking to ensure that your PWM bitrate is set to 16-bit.
