Hello,

I noticed an issue with American DJ Mega Bar LED fixture. This fixture is supposed to be about 1m long. When I compare 3D view with other fixtures, it is clearly too short.

Can you please have a look at this fixture (dimensions and photometric data)? In fact I noticed same issue with all variants (fixture #229 and #230).

It is also related to same urgent customer request (see my post about Stairville RevueLED 120 COB DMX). It means, if possible for you, it would be so useful to me to get it also by the end of this week. Thank you in advance for your precious help!

I noticed that you added it to L8. Thank you.

I checked three variants :

  • 229: American DJ Mega Bar LED 3ch
  • 230: American DJ Mega Bar LED 4ch
  • 2745: American DJ Mega Bar LED (11ch)

  • 3D shape/size: OK
  • 2D icon: OK
  • Lens: OK
  • Beam angle: OK
  • Illuminance: NOK
  • DMX channels: NOK

Illuminance

L8 max lux information:

  • 755 @2m
  • 335 @3m
  • 121 @5m
  • 84 @6m
  • 30 @10m
  • 8 @20m

If you look at photometric data, you can get illuminance at 3m: 104 lx.

How did you define luminous flux at 317 lm? May you decrease it to reach 104 lx @ 3m?

DMX Channels

For 3, 4 and 11 channels variants, I noticed a strange things, when looking at color channels, color faders are not set to 100%, but to 95% (red), 90% (green) and 85% (blue). But I also see that 100% button is clicked. Is it a mistake?

Illuminance has been fixed. Thank you!

What means these 95% (R) / 90% (G) / 85% (B) fader values? I presume that it is something not significant. But I would be interested to understand why.
