I have a range of IR illuminators here, including a Blade. I can tell you now, a low cost 50mm AS LED under 150 yards gives a smoother more crisp image overall, great value for money... I was testing the other night, and some of the torch options are over rated IMO...
Test properly yourself, it's the only way..
Highseater send me your address, I'll send you the one I use FOC...
Can I also send a torch out to a group member, then just pass it around to other members after a week of use, then you can check yourselves first hand...
A pile of Alpex 4K LRF shipped out to customers across the UK yesterday, more are arriving in 1-2 weeks, the Alpex 4K standard we have in stock now also. So should be plenty who can test these soon.
