Random power question

[Dee]

House is finished (ha!) but I've neglected to put a power socket on the landing. 

Can I use a portable power pack to run a table lamp off? 

Don't want to start hacking away to put a new socket in.... Ta

LED battery powered light?

[Ferdinand]

I see no reason why not, except for the annoyance of recharging etc. Look up boat items?

 

What is the requirement - eg nightlight, low-luminance light to leave on etc?

 

But you are about to get 27 alternative suggestions.

 

Here are my three 

1 - Replace ceiling light with one with two directable spots.

2 - Use a low voltage one plugged in in an adjacent room, and run the small cable under a rug or carpet.

3 - Put a person detecting bulb in the ceiling light, so that it switches when someone walks in.

I'd put a socket in. Handy for the hoover.

Are you in a position to put a double socket in back-to-back with one in another room.

 

That works quite well.

@ProDave.... Actual Led lamps are stupid expensive and ugly..... Want a regular lamp that I can plug into a portable power pack but don't know what I'm looking for 

@Ferdinand  don't want ceiling light, too harsh, can't run cable as crosses too many doorways, can't put a socket off another one, don't want a nightlight/sensor

@Tempdont want to smash hole in wall now it's all looking tickety boo!

 

[ProDave]

I there anything, the other side of the wall, a cupboard for instance?

 

I can't imagine what sort of portable power pack you are expecting?

 

There is this sort of thing http://www.ebay.co.uk/itm/Ring-RPP265-Professional-Power-Pack-300W-Inverter-230V-AC-Mains-LED-Work-Light-/282672441252?epid=1036522425&hash=item41d09727a4:g:zWsAAOSwZM9ZzLh3

Mainly sold for jump starting cars but some like this have a small 230V inverter built in so can be used as a portable mains supply. Perhaps if the lamp sits on a table with a tablecloth to hide this underneath?

 

My life would be a lot easier if someone invented "wireless electricity"

@ProDave

You're right, I don't what I'm looking for but I'm sure it exists! 

I found this below.... Would that work? 

How much power does a table lamp draw? 

Enables you to operate your 230v UK standard appliances outdoors using a 12v car battery or portable 12v power source.

• Converts 12 Volt Dc 230 Volt AC
• Ideal for All 12v Cars, 4X4’s SUV’s & Motor Cycles
• Also Suitable for Caravans, Camping & Boats
• Operates 230v mains appliances from 12v battery power (laptops, stereos, TV’s DVD’s , Phones etc.)
• Use for emergency power due to storms and blackouts
• Single 230v-50Hz 3-prong UK socket
• 300 Watt Peak Power
• 150 Watt Continuous Power
• Not Suitable for 24v batteries

[ProDave]

Assuming you have say a low energy 11W lamp, by the time that is converted to 12V that will draw over 1 amp from the battery, so a typical operating time of 50 hours from a fully charged car battery.

 

Thinking outside the box now, take a trip to a caravan shop and look for a 12V caravan table light, or simply change the lamp holder and convert any lamp you like to 12V and cut out the inefficiency of the inverter.

It's been done several ways:
