Need some advice is DX 10.5mm LED good for mini mag ?

Need some advice guys going to be buying some other stuff from dx so thinking about throwing this in while I am at it. Seems like a good deal for $3

I have an old school AA maglight mini and I need replacemnet bulbs for it anyway. All I plan on doing is drilling out the refelctor and poping this in. Just stick in some decent batteries and call it a day.

So my question does this seem like its a good idea or should I go with 3.5mm SKU 1105 or 5mm SKU 1105.

I would imagine bigger is better..

Thanks for the input guys

Check the MCD rating. A 14k mcd 5mm LED is just as bright as a 14k mcd 3mm or 10mm LED.

There's also beam angle. A narrower beam angle would give a brighter hotspot and less spill.

Then the LED vf(forward voltage). A LED with lower vf is going to be a bit brighter than a LED with higher vf, given the same input voltage. The lower vf LED will also be running at a higher current so it's more likely to overheat/burn out if you use lithium primaries though.

As for the size, using a 3mm LED would require very minimal modification to the stock Mag reflector.

If you aren't expecting much brightness-wise, yes, it will work. I've run white LEDs directly off of 2AA's before, and I think it's not much better, if at all, than the original incan. I agree with the previous post though, you'll be better off with a 3mm or 5mm LED.

You might want to check those SKUs.

What sort of voltage are you planning on feeding the LED? Even with the lowest Vf 5mm LEDs I've used, AAs don't give enough voltage to usably light them up for very long at all. I haven't tried using 2xAA lithiums.

Check the MCD rating. A 14k mcd 5mm LED is just as bright as a 14k mcd 3mm or 10mm LED.

There's also beam angle. A narrower beam angle would give a brighter hotspot and less spill.

Just to clarify, the millicandela is an intensity unit. So a narrow beam at 14,000 mcd will just have a smaller hotspot than a wide beam at 14,000 mcd.
