Magnetic Lamp

I was thinking of buying two of these lamps for my miller and grinder but they come with a EU plug if I put a 13amp plug on will the 240v blow the bulbs.

Most unlikely

… The permitted deviations from nominal 220V and nominal 240V overlap

[all fiddled in name of harmonisation some years ago]

Hi John

Specification:

• 100% brand new with high quality

• Plug: EU Plug

• Number of LED: 30pcs

• Voltage: 220～380V

• Power: 2W

• Light Color: White

• Light pole length: 31 cm

• Base diameter: 35 mm

• Thickness: 28 mm

• Wire length: 130 cm

 

As the item spec says the voltage will not be a problem. The plug can use an adaptor or you can change the it for a UK spec with the correct fuse size.

Well said that man!! Now we are out I hope we can kick these non engineering "solutions" into touch!

I bought 2 of those, but I won't be buying any more. They have a capacitor/resistor dropper inside the base and 2 very thin wires up inside the metal Swan neck to the leds. If the insulation fails the Swan neck is potentially at mains voltage and it's not earthed, so potentially lethal. Spent far too long modifying them to work off a transformer.

Thank you for your replys, Duncan has put me off as I like things earthed

Thanks for the warning. I wonder if they are legal in UK?

I, and I believe many others here, have the IKEA LED lamps with flexible stem. Do you happen to know whether your point applies to them?

My example was the same as Duncan's: the power supply and construction are both very simple and – in my view – unsuitable for use in a workshop. Safe enough on a domestic sewing machine on a dining table, but risky in an industrial setting. For example, electric shocks are much worse on concrete than carpeted wooden floors.

It's possible that some of these lamps are better made than others. However, in the UK, I'd be nervous of buying any cheap electrical appliance that didn't have a 13A plug fitted already.

I see Amazon have small solid looking magnetic machine lamps for 2 or 3 times the price which do come with 13A plugs. Not taken one apart, but these look a better bet.

I dismantled the Chinese angle-poise machine light on my mill when it developed an intermittent fault. Cost about £100. It's properly earthed throughout and runs a 12V car headlamp bulb from a sealed switch-mode power supply. The head is waterproof, and engineered so it doesn't overheat. The power supply doesn't output anything unless a working bulb of the correct size is fitted, which made the fault hard to diagnose – turned out to be an iffy spot-weld inside the bulb. Although safe, I rarely use it because it causes glare and shadows. Instead, six strip lights on the ceiling flood my whole workshop with light.

The swan neck doesn't look very long on the one pictured by scaling it against the plug.

Personally I'm not keen on magnetic tooling on the mill, it attracts too much swarf!

The best thing I ever did in my garage was to replace the old fluorescent tube lights with LED batten ones, they put out so much light you almost don't need local lighting on the machines. i put one above my lathe and one over my work bench.

I was never working with enough light.
