LED lamps with the B22 bayonet cap are a key upgrade point in decorative and general lighting installations where bayonet-fit holds firm. Use cases: hotel rooms, hospitality suites, display areas, residential-style luminaires, and any fixture with a B22 (bayonet cap) socket.

OSRAM B22 Base LED – Why engineers specify them

The B22d cap (also labelled BC-B22d) is still common in many regions for general lighting. When a facility has many B22 fittings, using OSRAM LED lamps in that base avoids rewiring or changing fixtures. The LED version delivers:

Much lower wattage for the same luminous output, reducing energy and cooling loads.
Lower heat—important in decorative luminaires or enclosed fixtures.
Longer lifetime—fewer relamps, less labour in maintenance.
Same base-form fit — keeps installation simple for retro-fits

For procurement, this means you can standardise across many rooms/fixtures, reduce stock types, and avoid rewiring new sockets

OSRAM LED B22 – Technical Specs and what to check

Here are typical specs:

Power consumption: e.g., 6.5 W replacing ~60 W incandescent equivalent in a GLS shape.
Luminous flux: ~806 lm output from 6.5 W LED in one example
Colour temperature (CCT): 2700 K warm white is typical; other variants may go up to 4000 K.
Colour rendering index (CRI): CRI ≥80 typical; indicates acceptable rendering for general lighting.
Lifetime: e.g., 15,000 h rated life on one model
Voltage: 220-240 V AC mains – direct fit.
Shape & dimensions: GLS shape, Diameter 60 mm, Height 104 mm for one model.
Beam spread: often ~300° for general lighting versions

What to check:

Ensure the base type is B22d and the fixture uses bayonet cap — wrong base = bad fit.
Confirm the lamp shape (GLS, Pear, Filament style) fits within clearance of existing shade or decorative cover.
Cnfirm CCT/CRI suit the space (warm vs neutral, decorative vs task).
onfirm dimming requirements: many LED B22 models are non-dimmable; if dimming is needed, ensure you select a dimmable variant and confirm compatibility with the dimmer.
Verify fitting is tolerant of the height and diameter of the LED lamp — if the old lamp was shorter, the new LED may protrude or disturb shade geometry.

OSRAM B22 Range – Typical variants worth stocking

OSRAM LED GLS 6.5 W B22 Dimmable Warm White Clear (≈806 lm, ~60 W equivalent)
OSRAM LED B22 8.5 W Warm White (≈806 lm in one listing)
OSRAM LED Retrofit Classic P B22d 4 W / 470 lm (≈40 W halogen equivalent)
OSRAM LED Star Classic 2.5 W Golfball B22 Warm White (≈25 W equivalent decorative)

For a maintenance or retrofit programme, you might choose:

Low-output decorative B22 LED for accent lighting (2.5-4 W).
General ambient B22 LED for rooms (6-8 W, 2700 K or 3000 K).
High-flux variant if large decorative fitting needing high lumen output.

Procurement & Maintenance Considerations

When replacing many fixtures, standardise on one CCT and one variant size to simplify spares and maintain colour consistency.
For decorative fittings, ensure the B22 LED’s height doesn’t affect shade geometry or shadow patterns.
In dimmed circuits: verify the dimmable version if required; non-dimmable will cause flicker or reduced life.
If you’re retrofitting old halogen B22 lamps (40-60 W), check that the lighting level (lux) remains acceptable with the LED equivalent – some older lamps were higher wattage for brightness, not just decorative.
Maintenance intervals extend significantly, but keep lamp batch information for future replacements to avoid visible variation in colour or brightness between lamps.
Consider heat and ventilation: although LED generates less heat, in an enclosed decorative fitting you still need to ensure no thermal risk.

Comon mistakes: mixing warm white (2700 K) and neutral white (4000 K) in the same zone; choosing non-dimmable LED where dimming is used; overlooking the shape/length difference so the LED sticks out of shade.
