I'm having trouble finding lumens for EXIT signs that are to be included in the Lamp Purchasing calculator. Pretty much EXIT sign cutsheets do not show lumens because these are EXIT signs and normally nobody cares for lumens on EXIT signs, just mostly wattage, rated lamp life, and regional compliance. Do we really need to provide lumens or even rated lamp life for EXIT signs, especially if they're LEDs?
I mean this is ridiculous, doesn't GBCI understand that EXIT signs do not usually have lumen information? Is there any way they can exempt EXIT signs from providing lumens, and instead just identify and provide proof that it is LED or some other non-mercury lighting fixture?!?!?!

Hi Edgar,
One thing I've done on past projects is only fill out the calculator enough to show that any mercury containing lamps are offset, then just upload a schedule or cut sheets showing that everything else is LED.
So the calculator might have 2 lines for mercury-containing lamps and 2 more lines for LED lamps to get the final number down below 35 pg/lumen hour. Then it is clear that the threshold is met, so I don't spend time putting the rest of the LED lamps into the calculator.

Ok, I will role with that. Honestly, for this particular innovation credit, they should provide some clarification for emergency lighting like EXIT signs.
Thank you.

We are targetting this credit in Innovation for LEED BD+C: Core and Shell v4. We think this is an easy point considering as all lights are LED, thus no mercury content. For the submission as a core and shell project do we need to submit only datasheets to confirm LED lights or is there other doc/commitment we need to submit to ensure tenant will follow the same requirements (e.g. commitement to not purchase any lamps with mercury content..)?
