DIMMING

Ambient DimTM technology from Specialty Lighting makes the Graffiti fixtures ideally suited for hospitality and residential settings. Here, both price and performance are key value drivers. As an optional feature, Ambient Dim enables Graffiti fixtures to match both the color and warmth created via incandescent sources through the entire dimming range but with all the efficacy of LEDs.
Ambient Dim TM is expanding with 3 color range options including : Full Range 30-19k | Mid Range 30-22k |  Warm Range 27-22k.

 

Driver and Control Choices

Driver selection is a big deal and we all know not all LED is equal. Specialty Lighting believes in providing you with choices and presenting the trade-offs between those selections.

drivers
  • ERP (our standard) 0-10v (C1) Dimming down to 1%
  • ERP (our standard) Triac/ELV (C2) Dimming down to 3% (depending on dimmer)
  • Lutron Hi-lume (L2) Hi-lume ~3% (depending on dimmer) 2-wire Driver
  • Lutron Hi-lume EcoSystem (LTB) Hi-lume 1% with
    Fade-to-Black (former H-Series) digital EcoSystem Driver
  • Lutron Hi-lume Premier 0.1% (LTP) Hi-lume Premier 0.1% with
    Fade-to-Black digital EcoSystem Driver
  • EldoLED 0-10v (E1) Logarithmic Dimming down to 0.1%
  • EldoLED Dali (E2) Dimming down to 0.1%
  • EldoLED 0-10v (E3) Linear Dimming down to 0.1%
  • EM Pack Dimming driver with emergency battery backup

All drivers are field replaceable*

Bits about our Drivers

  • ERP Power – This is our ‘standard’ driver and is selected with C1 or C2 on our ordering codes. You have a choice of 0-10 or phase cut control systems. We recommend the 0-10 to assure deeper dimming. Phase cut is quite variable and has a significant variation at the bottom end depending on the dimmer.
  • EldoLED – We have 3 selections. All of these digital choices will achieve a 0.1% dim level. EldoLED recommends using log dimming curves with linear control systems and linear driver curves for log control systems. Here is a useful white paper link from eldoLED about selecting dimming curves   "Why you need Dimming Curves ".
  • Lutron – This set of drivers are optimized to work with Lutron control systems. Stay tuned to the datasheets for change in these offerings as Lutron has recently been inconsistent in the availability of these selections for both supply chain and commercial reasons. For example, the two-wire version (L2) is due to be discontinued sometime in 2024. We also have been told Lutron will be switching their EcoSystem to a DALI 2 protocol. We love Lutron but stay tuned.
  • Flicker – Stroboscopic Flicker is something we pay attention to, and we believe reducing the negative effects are important. The benchmark metric is the IEEE 1789 specification. Both EldoLED and Lutron drivers fall into the no effect category while the ERP drivers, mostly, fall into the no effect to low-risk areas. If stroboscopic flicker is important in you application, we recommend the EldoLED or Lutron drivers.
