LED lamp STAR 50 4.9W 840 GX53-OSRAM 4058075433465

Flat LED lamp with GX53 base, ready for immediate replacement

This is not just a regular bulb — it’s a direct, safe, and efficient replacement for older 40 W reflector lamps. Its compact profile and weight of only 28 g allow installation even in narrow fixtures with limited space. No wiring modifications are needed — simply connect it in the same way as your previous bulb, and instantly enjoy stable, flicker-free light.

Why it performs well in practice

The 4000 K color temperature delivers a neutral white — not too cold like midday sun, not too warm like candlelight. It performs excellently in kitchens, hallways, stairwells, and retail spaces. A color rendering index (CRI) above 80 ensures colors appear natural — food on a plate or wall paint retains its true hue. Even light distribution (120° beam angle) eliminates shadow spots, while the frosted glass diffuses light without harsh edges.

High color consistency (≤6 SDCM) means that if you replace multiple lamps in one room, all will look identical — no visible difference between the first and last installed bulb.

It is not dimmable — and this is intentional. In “always-on” applications (e.g., under stairs, near doors), where consistent illumination is required, dimming would be unnecessary and potentially risky. The absence of dimming control also reduces electronic components, resulting in longer lifespan.

What ensures long-term reliability

15 000 hours is not just a marketing figure — it’s the result of testing at 2.7 hours per day (equivalent to nearly 15 years in a home). The lamp withstands 100 000 on/off cycles, making it suitable even as an “emergency light” or in high-traffic areas (e.g., bathrooms). It contains no mercury, emits no UV/IR, and operates directly on standard mains voltage (220–240 V) without additional transformers.

If installing in an outdoor fixture, ensure the fixture itself has adequate protection (IP44+). The lamp itself has IP20 rating — intended for use in dry indoor environments only.

All this is backed by a 3-year warranty — no special documentation or registration required. Simple product. Simple operation.
