dave101, I don’t have any aircraft hangar bulbs or 30,000 lumen mega-flooders to compare against. But the D18, even in an incomplete dev kit form, is easily the brightest flashlight I’ve ever tried. It won’t be suitable for lighting up an entire hangar, but it sure gives a bedroom a surreal holy aura. To get an idea what it looks like, turn on 15 to 20 60W-equivalent light bulbs all at once.
Let me know if you need anyone else to do a review?
