XM-L EZW T5 warm white for 4.92$ at GoodLuckBuy

OK, thanks for the info. The mower is 12v and yes has an alternator. I already upgraded from 21 watt light bulbs to 27 watt (which did make quite a difference), but I didn't want to push my luck with how much draw the alternator could handle / recharge for. I intended to rewire in such a way that I could always put the stock bulb sockets and bulbs back in place. I was thinking something along the lines of an old CPU heatsink and a couple empty 52mm reflector/heatsink modules from DX. They would also sit behind the stock headlight "lens". I didn't want the lights mounted anywhere else on the mower because they would end up looking too redneck (and I'm not into that). Plus it would be a "sleeper".

hmm, glad I did a test order first. As mentioned above, solder job looks really ugly, too. I've reflowed several xm-l, but don't think I want to try this style

as much as I like aspherics, I don't like the beamshots of an mc-e behind one at ALL

my uses won't be doing any white wall hunting, and I will use multiples, so i think I'll be hard pressed to notice artifacts. but....i really don't know...yet ;)

I'd be surprised if the alternator couldn't take another 2A...but playing it safe is a good idea. So is non-redneck 'sleeper', and using an inner reflector though I wonder if 56W of halogen isn't pretty close to 24W of cree xp-G (...don't know...)

as far as redneck goes...they don't add lights to their mower...a real red-neck does a light spray of weed and grass killer on the whole lawn so they don't have to mow very often. I would never do that at my place though, since I rent

I'd say my KD C8 on high blows away the current lights except in terms of spill. A real redneck would probably just strap two KD C8's on the hood and call it done!

Of course I could always go with a high-powered XM-L headlight (literally speaking now - a light on my head).

You can also buy this led, for low consumption aplications inside of a wardrobe for example...

that would be the budget (ie wise) solution - since you could use it on your bike or at work, too...

not sure if the ezw is best suited to headlamps though - unless maybe you wanted to use an sla battery in a belt pack....

I have purchased from them about 10+ times over the last year, never had any problems with them.

They don't say if they are 6 volt or 12 volt, might be a bit of a gamble but I'm sure its not 3.2-3.6 as described.

I think it depends on how you wire them, ie 6V across each +/-, or 12V across ? one from each side ?

Why a SLA, why not simply 2x 18650 and boost driver? ;p

At first I thought they were 6-12V but then after reading this posted up the top:

http://www.cree.com/products/pdf/XLampXM-L_EZW.pdf

It says available in 6 or 12 volt versions.

I'm just going by what that says, I have no idea myself.

or a bunch of AAs

but...point a suitable driver out for me and I'll test it :-P

ok, let me re-state, a driver <= $15

Current is too high though, you'd have to figure out how to disable high mode and leave only low/med.

The tint is nice :-)

It's a 6V T6 from here:

Picture in their shop is wrong...

thanks for the link.

i suppose you could also parallel two of them and run two chips w/ each

which would be close to spec current?

received 4 emitters today. inspected 1 - dome is slightly off center and solder to pcb is a little suspect. no time to test today.

two weeks, that's pretty quick delivery!

nice thread

where to buy one xm-l 6v cool whrite?

Anyone tested these?
