    I am ok too.. but my vote would be bias since I am next in line

    But I can also delivery anywhere here in north bay or around SF area.. since I go there a lot.

    I live in Berkeley but work in Mountain View so I would be happy to be a middleman for transport if that ever helps anyone in line.

    Not sure where the line is, but I'd like to step in line to borrow.

    Need to try and make some informed decisions on lighting without needing to trust my eyes :D

    Picked up the PAR meter today.

    Will try to test par fast so we can move along

    @jorahx4 has it now. We meet half way Tuesday.

    Thanks for letting me borrow it, it was very helpful! No wonder some sps wasn't doing good, light was really weak.

    Around 200 for sps areas... and sometimes 50 for other places... I added the second kessil and have them at around 50% and everything is happy again.

    @jorahx4 - Fairfield
    @Randy moss - Oakley
    @reeftails - Martinez
    @Rostato - Fremont
    @Mozby - Union City
    @DubbaD - Los Gatos
    @wwu123 - Los Altos
    @sfsuphysics - SF
    @henergizer - Hayward (SF or SSF)

    For those on the list here, note that we now have another PAR meter.
    See :
    And people already on this list get priority to be fair.

    We bought a new wand and case for the old meter.
    So if in Fremont or Union City, please let me know so I can swap it out.

    Just out of curiosity, when my turn comes up, is there a way to make sure that I can get the 510 since I am running LEDs? - Dustin

    It may be something as simple as allowing the next person to jump ahead of you if the other one isn't currently available.

    Just looking at the list, I see the person before me is in Los Altos, which makes me not want to get it if that's the only reason for going down there, so I may pass my turn.

    Fine by me... I’m down in Los Gatos, but can make a drive if needed. I don’t mind waiting if needed. I screwed things up the first go round and missed my turn, so whatever I need to do.

    I could be wrong but I thought they both performed fine for LEDs but the 510 better represented the blue spectrum better and was more accurate when measuring Kessils.

    They are both fine for led’s

    Sounds a bit contradictory, might be fine for white LEDs, perhaps white LEDs we'd use in our homes (warmer)? But many LED fixtures have a large number of strictly blue LEDs,

    That said not sure what sensor the first meter has (i'm sure it says somewhere in this post) *me = lazy*, but here's some correction factors
    Since par values are additive you can simply count how many BLUE LEDs you have and adjust accordingly, Find PAR with no blues on, then only blues and multiply by 1.12 (if using electric sensor.

    Looking at the various sources it two things pop out, violets it has a hard time with, and extreme reds it has a really hard time with, the later isn't that big of a deal though since you shouldn't care about that value as that only adds color not growth .
