OSRAM B15/B22 LED Lamps

OSRAM LED B22 Bulbs – B22 base retrofit LED lamps

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.
