led wall sconce lighting document check

Model file desk for an LED wall-sconce proposal

1. Identify the model

   Match the quote model string, shade or glass code, source count and switch option to one revision. If a factory substitutes a different arm that still uses LED, record it as a new line rather than a silent equivalent. Finish samples do not replace the model string on the quotation.

2. Check interfaces

   Review backplate and projection in mm or in, input voltage, driver location and switching. An on-fixture rocker, wall-only control or 0-10V dimming port must be named. Confirm dry, damp or wet location against the intended wall. Correlated color temperature in K, color rendering index, luminous flux in lm and, if both watts and flux are named, luminous efficacy in lm/W belong on this sheet with mounting height and beam angle; they are not implied by an LED marketing line. Rated output current in mA is only relevant if a remote driver is quoted separately. If the nameplate shows 120–277 V AC, copy that string from the quoted model rather than assuming every sconce accepts that range.

3. Request supporting records

   Ask for product-specific listing or performance documents where the buyer’s destination requires them. UL product certification and a DLC QPL row are separate files. Neither file becomes a credential of Wall Sconces Sourcing, and neither file by itself proves the wall is lit correctly. An IES photometric file must match the optic, shade and source count on the quote, not a sibling SKU. Unresolved finish, room-use or switching questions stay listed before order approval.

Constant current versus constant voltage language appears on some driver labels. For a complete sconce the buyer still needs the factory to state the supply the luminaire expects, not a generic driver swap rule. Ballast-bypass tube rules do not apply to this family; keep tube retrofit language off the sconce brief. Compare light output and beam toward the task before treating another wattage as an upgrade. An LED module photograph is not proof of dimming compatibility.

Sample observation, when the buyer requests one: set the sample on a wall at the stated mounting height, measure projection from the finished surface, operate the named switch at the intended seated or standing position, and photograph the shade against the specified finish under the quoted CCT in K. Record environment (dry interior wall versus damp bath opening), method (tape measure plus switch reach), observations (projection, handed orientation, glare toward the task) and what remains untested (field voltage drop, listed dimmer compatibility, IES file versus installed optic). Repeat those four notes on the quotation revision rather than treating the sample as a lighting calculation.

Return to inquiry options if the LED line was only a placeholder, or to supplier matching when two factories used different model strings for the same typical. Read the procurement checklist before signing a revision.
