Ceiling light -- maximum bulb power...?

esuhl

I've just replaced a ceiling light in my hallway. The new fitting is more modern in style, but the design elements are very similar -- they both have a metal frame with glass side panels, which hangs on a chain attached to a ceiling fitting.

The old light is ancient, before "energy saving" bulbs became prevalent. It takes bayonet bulbs and is marked 100W maximum.

The new uses E27 bulbs. It has thicker gauge wire, yet the power limits are 6W LED or 28W halogen.

Can I use a 30W CFL instead...?

I presume the only issue would be heat (as the cabling looks fine), but presumably a 30W CFL bulb would be cooler than a 28W halogen...?

A 30W CFL bulb will emit nearly as much heat as a 28W halogen. Depending on the design of the fitting, that might or might not cause the CFL to overheat. It will emit a lot more light than the halogen, so might be too bright anyway.

The 6W LED limit specified suggests that the fitting might cause higher powered LEDs and CFLs to get too hot - they last longer when kept cool.

Thanks, WobblyDog.

It sounds like I should be fine with a 30W CFL if a 28W halogen is cooler. I can't imagine the current being a problem.

This is the lamp in question:



The design is open at the top and bottom.

What really puzzles me is the 6W LED limit. I can't understand how two fittings, can be so (apparently) identical in construction and materials, yet one can cope with a 100W incandescent bulb, the other with a mere 6W LED.

A 6W LED must run so much cooler and draws so much less current, that... unless there's a hidden component made of chocolate... I can't see how the power ratings make any sense. :huh:

Massive changes in fire safety legislation between ancient and new product?

Recommended/ likely room use (central hall/ stairwell), fire compartments, open bulb not enclosed shade?

Or maybe I am a tad too Building Regs obsessed. :money:

I can’t help however would you be able to tell me where you purchased it from? Quite like the design!

Also if you have used it what do you think?

Thanks
