I purchased this infrared torch off eBay: UltraFire 5W IR Infrared Red CR123A Torch With Pouch Set WF502B-5WIR (For NVG)
It arrived and provides marginally adequate IR illumination out to 20 yards or so (for my night vision camera).
Today I came across these infrared drop-in replacements.
1 watt: 1W 850 nm Infrared IR LED Lamp Replacement Bulb 501B 502B 503B C1 L2 6P G2 C309S
5 watt: 5W 940nm Infrared IR LED Replacement Bulb for Surefure 6P Ultrafire 501B 502B L2
The 1 watt unit shows a single emitter in the bulb. The 5 watt unit shows 4 emitters in the bulb.
The unit I purchased only has a single emitter in the bulb. How can I tell if I am getting 5W output? I am wondering if they call it 5 watt but simply send you a 1 watt bulb and think you'll never know the difference?
