    Variances in output between equal lights?

    So Ive used a Dinotte 400L for a couple years and just got a second. The new one is much brighter when side by side with the same lens setup. Swapping batteries gave no change.
    I haven't heard of Dinotte improving the 400L, is this an individual variance? I know this happens with the Magicshines but doesn't the quality control of a good company like Dinotte prevent that?
    The difference is big, the brighter (new) one is a more blue/white color and has more throw.

    They may have changed the bin of the LED that they are using. Even though they may have not advertised a change it is very likely that they changed to a different bin as it became available as it is sometimes hard to get older (yes 2 years is old) LED's

    My thoughts entirely....A couple years ago I wrote Dinotte to ask if they were upgrading any of their lights. ( I wanted to upgrade my 600L with Cree R-2's ) They told me then that they weren't using the Crees but that I might benefit from a newer version of the 600L. That got me thinking. Maybe they did get a batch of better binned P-4's. You can't ask Dinotte direct questions about their electronics because they won't answer...which...is a real bummer. Likely your 400L has better leds, optics or a driver that is over-driving the leds a bit more.....or.. perhaps a combo of all three. Just be glad that it's better.
    I still love my 600L. It is a great light.

    There is also the possibility(though not as likely as a new bin) that the older light has just got dimmer over time, especially if it has been allowed to get hot on a regular basis during it two years of use.

    Beamshots please.

    Lumen maintenance is something like 70% over 50,000 hrs... I assume you've got nowhere near that amount of use out of it so the LEDs should still be "fresh".

    I don't have the camera ability. I would go with the different bin idea. It's never been overheated.

    Depending on how much more you like the newer 400L, it might be worth giving Rob at Dinotte a shout to see if a trade-in is possible ( just the light-head that is ). You might have to pay a little more but it might be worth it if the newer version is significantly brighter....just a thought.

    Dinottes response, just as suggested by others. Though they won't comfirm nor deny change.

    My guess is it's a combination of three things.

    1. *color - the newer led probably has a slightly better color.
    2. *lensing - the optics are probably slightly better
    3. *LED - the lEDs have become slightly better.

    If it becomes a real issue, we can take it in and look at refurbishing the
    light.

    Thanks
