  • 1.  Lighting standing gallery signage

    Posted 19 days ago

    Hello All!

    I work in a historic space where most of our didactic information is presented on self‑standing 17×11 signs. Because our light levels are kept low to protect artworks, it can sometimes be difficult for visitors to read the signage. We've been experimenting with clip‑on music stand lights to improve visibility, but they only last about a week before needing to be recharged. With the number of signs we have, this isn't a feasible long‑term solution. 

    I'm wondering if anyone has recommendations or suggestions for effectively lighting self‑standing signage.

    Thanks!

    Each instance for lighting signage is different, however, I commonly use a Soraa 9-degree spot on signage.  These tend to put out a lot of light, but concentrated.  You'll probably want to filter out the light intensity.  By being such a small spot, the light tends to stay within the parameters of text panels.  If you have a long horizontal text panel, occasionally, a spreader will suffice and will knock down the light levels.

    The trick is providing enough light that the text is readable, yet your text panel doesn't appear overly important in relation to the object.  It's a balance.

    Adding to Ronald's message...

    Geometry plays a key role here. If the sign is relatively low off the ground, you need to be sure that the accent light is not behind where the visitor would typically stand to read the graphic. Otherwise, the visitor will cast their own shadow on the sign. (It's like kitchen lighting, you don't want to slice an onion in lighting that is blocked by your shadow!) Conversely, if the accent light ends up being from a track or other ceiling mounted position that is a relatively flat geometric angle, all the visitor may see is the reflection of the light in the graphic; this is known as a "veiling reflection". The sign will be lit, but the visitor will not be able to read it. 

    Always do a mockup before determining the location (height and distance) from the 2D or 3D object you are lighting – I promise, you will not regret taking the extra step!

    I also hope you will heed Ronald's comment that a Soraa 9° lamp is wicked bright and you will likely need to reduce the light output, either with a dimmer designed to dim this lamp, (layers) of window screen, neutral density filters, etc.

    You might also consider a less robust lighting source/fixture like a Luxam Micro Track Fixture; Of course there are other options as well. Whether track or ceiling mounted, using a low voltage (12-48 volt) lighting fixture rather than 120v lighting source (like the Soraa lamp) will make retrofitting lighting into an existing facility a lot easier.

    Finally, you might consider bring low voltage power to your signs and deploying a low voltage picture light that is always getting power. Leave the charging anxiety to your electric car!

    Good luck!

    Just to build on the Soraa thread: The SNAP system allows you to put different filters (up to 2 per lamp). In your case, the louver lens would be nice as it will reduce glare by blocking direct view of the bulb. There are also other lenses that change the shape of the light, rectangular, oval, etc.

    One point of clarification, when using the window screen to reduce the light levels (which is a solid technique), make sure it's the metal window screen and not the fabric window screen. It seems obvious, but I didn't want you to find out the hard way in case it wasn't clear.

    Lastly, let the group know if you even have track available in your case, I'm guessing you don't have any track in the historic house.

    Questions:

    How many do you have to light?

    Could you run discreet cord to your signs?  LEDs don't need heavy cord run to them. Maybe you could hide through transformer and run clear or back cable to your sign, run up the back of the sign and connect to a small LED fixture that's perched at the top of the sign. These rabsfowmers could then be put on a timer. I use geenie timers. They can be turned on and off remotely if you have special events outside of your regular hours.

    Good luck to everyone here, please let us know what you came up with even if ti fails, we'll all learn together....

    Cheers,

    Matt

    Hi Ronald,

    Thanks for the tip! We use Sorra bulbs for our tracking light already, so it should be easy to experiment.

    Hi, Abby,

    I don't have an answer but I'm so glad you asked the question! We have a similar problem here and the last idea we landed on is the one you already tried. It's helpful to know that it's not a sustainable solution. Here, we also have a related problem: we don't have sufficient staff to turn individual lights on and off every day. I hope that someone has an answer!

    Regarding the question about turning gallery lights, or those in period rooms on and off, one solution involves the use of wi-fi enabled switches. They can control single-outlets, or larger circuits. The variety of such controls is considerable, so I won't go into detail here. An electrical contractor or lighting consultant should be able to identify switches to suit your needs, as well as the methods for activating them.

    Best.
