A spotlight-housing RFQ should begin with a firm product boundary: this is a housing-only purchase, and the light source is not included<\/strong>. The buyer must separately identify the intended lamp, holder, voltage architecture and any transformer or driver.<\/p>\n\n\n\n

The goal is to close every physical and electrical interface before approving drawings and samples. A housing that looks correct can still fail because the lamp envelope does not fit, the holder position is wrong, the aiming range collides with the ceiling, or the approved finish cannot be repeated.<\/p>\n\n\n\n

Keep the housing separate from the lamp<\/h2>\n\n\n\n

GU10 and MR16 are often used together in product descriptions, but they do not mean the same thing. GU10 commonly identifies a cap\/holder interface. MR16 is widely used as a lamp-form description and does not, by itself, determine the holder, supply voltage or control arrangement.<\/p>\n\n\n\n

Le GU10, MR16 and E27 spotlight housings<\/a> category is a product-browsing path. The RFQ must still name the exact lamp cap, holder, lamp envelope and electrical architecture for each housing model.<\/p>\n\n\n\n

Do not ask the housing supplier to quote \u201cMR16 compatible\u201d without a dimensioned reference lamp. Two lamps with a similar front diameter may differ in body length, rear geometry, heat-sink shape or connector clearance.<\/p>\n\n\n\n

Create one interface stack<\/h2>\n\n\n\n

Use a single sheet to align the parts that must fit together.<\/p>\n\n\n\n

IEC 60061 covers lamp caps, holders and gauges as an interface system. That is why a cap name should not substitute for an actual compatibility drawing.<\/p>\n\n\n\n

Choose the mounting form before asking for dimensions<\/h2>\n\n\n\n

\u201cCut-out\u201d applies to a recessed installation. A surface-mounted cylinder, track-related body or pendant housing needs different mounting information.<\/p>\n\n\n\n

For a recessed housing, request the ceiling cut-out, minimum cavity depth, visible trim dimensions, spring position, allowable ceiling thickness and clearance needed for installation and removal.<\/p>\n\n\n\n

For a surface-mounted housing, request the mounting-plate hole pattern, base diameter, wiring-entry position and the relationship between the plate and visible body. For a pendant form, add canopy, suspension and cable details.<\/p>\n\n\n\n

Never copy one mounting dimension across a product family. The RFQ should identify the model and revision beside every drawing.<\/p>\n\n\n\n

Verify the holder and electrical boundary<\/h2>\n\n\n\n

State whether the quoted housing includes the lamp holder. If it does, identify its type, rating, lead length, insulation, mounting method and replacement procedure. If it does not, show the holder interface needed by the buyer.<\/p>\n\n\n\n

Also state whether any transformer, driver, connector or terminal is included. A housing-only purchase must not quietly acquire electrical assumptions from the reference lamp.<\/p>\n\n\n\n

The destination market, supply architecture and lamp selection determine which electrical documents may be needed. IEC 60598-1 provides general luminaire requirements, but it does not prove that a particular housing assembly, holder or wiring arrangement is suitable for the buyer\u2019s final combination.<\/p>\n\n\n\n

Draw the permitted lamp envelope<\/h2>\n\n\n\n

Place the proposed lamp outline inside a sectional housing drawing. Mark:<\/p>\n\n\n\n
