    Default 6100 hv difference in PAR's

    Have issues with 2 mitras 6100 hv's

    Using a seneye reef to compare the 2 lamps there is 300 odd PAR difference between them at the surface on exactly the same settings

    One lamp was bought new. Nov 2014. The other came secobdhand with a system, no idea of 2nd lamp age.

    The new lamp is the master, firmware 1.17. Old lamp is slave on 1.07.

    1 - would difference in firmware cause communication problems between the 2 to effect PAR this much. The naked eye can just make out the difference on the sand bed.

    2 - I was thinking of old pucks but this doesn't make sense as the old lamp is giving the higher PAR.

    3 - could there be a fault on the new lamp

    I've been struggling with settings all last year worrying about intensities. I borrowed a seneye to get me in the ball park the after a couple of days of testing I discovered this.

    It really puzzled me and has caused me a lot of problems between the 2 sides of the tank.

    Please, please help. Am I missing something or just going crazy ?

    Thanks

    no

    right. and even if it was vice versa this difference would be more than unusual, the LEDs have >60000h lifetime in the Mitras (LH80)

    3 - could there be a fault on the new lamp
    I doubt that.

    you write
    exactly the same settings
    does this refer to all setings?

    - illumination run?
    - energy options?

    do the simple test:

    all lamps to 100% and full output and 65°C (energy options)

    in Master-Slave configuration: output manually 100% on all channels

    now: all LEDs in both lamps on?
    PAR readings similar (under similar conditions, of course)?

    Thanks for your replies, I think I may have sorted it.

    Well post back when I've done a bit more testing.
