    Are these suitable for fitting in soffits?
    Question by: Calum on 30 Mar 2024, 19:07
    No, they're not suitable. We have some other dedicated outdoor downlights that are designed for soffit installs:
    Answer by: Chris Horridge (Admin) on 2 Apr 2024, 09:56
    what is the difference between the LITE and PRO series??
    Question by: Christopher Gittins on 21 Jan 2024, 09:31
    The Lite is the more latest range and costs less. The Pro is the original version which is gradually getting phased out.

    The Lite CSP has multiple colour temperatures and wattage options in 1.

    The light output and performance of each are very similar.
    Answer by: Chris Horridge (Admin) on 21 Jan 2024, 10:13
    Is this IP65 rated from above and below? Would it be suitable for an outdoor soffit?
    Question by: James on 9 Feb 2024, 08:37
    The IP65 rating is just from below and its not suitable for outdoor use.

    This is the dedicated outdoor version, which is IP65 from the front and back:
    Answer by: Chris Horridge (Admin) on 9 Feb 2024, 08:48
    What dimmer units are compatible with these downlights. Do they require trailing or leading edge?
    Question by: Simon on 18 Nov 2023, 17:22
    They work with either versions. We recommend the Varilight V-Pro which has both dimming modes. You can change the dimming mode by rotating the knob in a certain sequence:
    Answer by: Chris Horridge (Admin) on 19 Nov 2023, 08:58
    What is the low voltage output on these?
    I presume it's DC output?
    Question by: James Taylor on 11 Apr 2024, 11:54
    It comes with a built in LED driver. Its essentially mains voltage. I can double check with Collingwood technical about this, but what is the background for this question? Are you using it in a non standard application?
