yep, just connect straight to 12v

I thought the same thing, they're a bit too cheap.... but the 8 I have up are working great, they're not normally on much, but I left them on overnight the first night I put them up to test them a bit... all still perfect in the morning :-)

plus, cheap enough to replace if they go wrong

they used to combine postage, deffo. did the first time I ordered :-(

Hmm, maybe I've cocked it up. I wanted two different colours, so added them to basket. When I went to the basket, they had got postage on each item. Same when I ordered the four. Couldn't see any way around it.
Not to worry, they are still ridiculously cheap.
I want them for interior lights for two vehicles. Perfect solution for that. No way I could do it cheaper, or better, probably.
I'm sure I can find a whole load of other uses when I get them in my hands.

I've got some Fluro light fittings banging around somewhere. Installed for about 12 months then removed.

Interested? They're in Somerset - I can probably get them to Southampton sometime in the next few weeks.

Be careful connecting LED light strip 'just to 12v' in a vehicle. The electrical system may be close to 12v at rest but nearer 14v when charhing and that will start to cook the LEDs.
I ruined some in the caravan till i remembered the mains hookup charger puts out 13.8v float.
A regulated 12v supply to them will make them last much longer

Tempting, let me think over the options. The existing fitting was 2x 6ft 75W tubes - 150W total - and replacement ballast is quite expensive.
The alternative is to try 12V LED strips which are 75W a piece, or some mini COB floods (which may also be useful for camping). Apparently ~20W LED is the same as 75W flourescent.

Ah, cheers for that. I'll look into it, get a regulator or something.

If you're looking for LED lights, there are just one one two on this site https://www.myled.com/

I've had some COB LED strips off them via ebay and the seem reasonable quality.

A 150mm strip @ 3 quid flood lights the printer bed really well. 3 or 4 would light a room.

Despite there massive range I still can't find a 30w led outside flood light with par and over ride ... anyone any ideas?

Just get a standard pir sensor with override built in and connect a basic 30w led flood to that

Most pir controlled LEDs on our buildings at work are done that way

Well done Pike, I was wondering who'd be the first to spot that!

Thanks Jules, I should have sussed that out myself.

the ones I bought have a little driver chip with them

I've had one in the back of a van lighting it up any time a door is open (front or back) for about a year and it's still going strong :-)

Well I have got those in the link Knighty put up.
Pulled out of the post box at 3.30, fitted a roll in the van by 6.00. (I had to have a snooze before I started.....)

Well chuffed. Flicking them on and off, and staring into them, like a cat licking it's paws after eating a bowl of cream.

I took the power from the original interior light, through a two way switch, so they even work with the doors.

Will test in darkness, soon as nature allows.

They're blue.........
