Colour Temperature

Colour temperature is measured in Kelvin (K) – the lower the number, the warmer the white light appears, while a higher Kelvin will appear cooler. Colour temperature generally ranges from 2700-3300K (warm) to 3300-5300 (cool) – and 6500K is daylight.

Equivalent Wattages Between Different Light Bulbs

As long as the technology developed, a LED light bulb can only use 8 watt power but light up similar brightness when a incandescent light bulb uses 60 watt power. There is equivalent wattage between different light bulbs. To stop making confuse, you need to know what wattage equivalent to each other. See the table attached as below.

This SYLVANIA pearl GLS incandescent lamp has a rounded body, extended neck and bayonet cap. This Industrial Rough Service lamp is rated at 200–250V and 150W, with a B22 fitting and pearl finish. The pearl finish obscures the filament compared with clear glass; this is a traditional incandescent lamp, not an LED.

The complete fitting must explicitly permit a 150W incandescent lamp and provide suitable heat tolerance, ventilation and clearance; a matching B22 socket or ceramic holder alone is insufficient. The bulb provides 2700K warm white light, with a 1,000-hour rated average life and dimensions of 80 x 160mm. Keep the total connected load within the dimmer's minimum and maximum limits, allowing 150W per bulb.

Frequently Asked Questions

Can I dim this SYLVANIA 150W rough-service bulb?

The existing specification marks it Dimmable, but these packaging views do not independently confirm dimming suitability. Verify actual-stock information and use an incandescent-compatible control suitable for the supply. Check minimum and maximum total connected load, allowing 150W per bulb and including other lamps. Universal compatibility and full-range dimming are not guaranteed.

Will this large 150W B22 lamp suit my fitting?

The carton confirms B22, 150W and 200–250V. Match the marked voltage to the intended supply and ensure the complete fitting explicitly permits a 150W incandescent lamp with sufficient heat tolerance, ventilation and clearance. Existing 80 x 160mm dimensions require actual-stock confirmation. Do not use it in a lower-wattage fitting. A matching B22 cap or ceramic holder alone is insufficient. Switch off the supply and allow the lamp to cool before handling.

What does Industrial Rough Service establish, and where was this batch made?

Industrial Rough Service is the designation printed on this SYLVANIA 150W pearl incandescent lamp's carton; it is not an LED and the wording does not by itself establish quantified shock/vibration performance, weather resistance or universal industrial compatibility. Existing 2700K, 1,000-hour life, dimmability and dimensions remain unverified. The carton states Made in France, while origin is saved as CN; verify actual stock and batch before resolving this conflict. The origin field has not been silently changed.
