Question: Does this LED Array require a resistor?
Document: This LED headlamp is very very bright.It is on a robot I built and lights the way for nighttime autonomous missions.highly recommend!
I looked at &#34;LED light bars&#34; but couldn't justify the eventual total whack from a tree branch. Individual lights were more cost effective.
Was expecting brighter. My Cree XML flashlight is brighter with one LED. There OK but that's about it, good as maybe backup light. Would not overpower my crappy stock headlights on an old 95 4WD Suburban. Was thinking of using them as auxiliary light on the side car of my Ural but not bright enough to see much of the road ahead at speed.Note: Just noticed the &#34;Cree TYPE led&#34; statement in the add.
I ended up adding a 0.5ohm series power resistor which dropped the power to 20W and was still plenty bright. Lite up the hill for more than 3 hrs, 8:30pm to 11:45pm. It beats any camping laterns out there and at a very low cost.
when I bought these I expected more light. I was comparing them to a tight beamed 9 watt flashlight. These work lights are for 50 ft away and about 25 ft wide. This is ft not yds.
very well built light i have them for reverse lights and they still have  a really nice flood beam for the price i don't think you will find a better light and being led theres no need for extra wires and relays since they draw so little  power
all i can say is WOW these are very bright  i put x2 of these on my jeep  great for in the woods. i bought a similar on at Tractor supply for 70$ and these  blow theirs out of the water  very impressed. I'm buying x6 more A++++++
Wow! do not look into these when you are setting them up. Blinding white light. good build but the brackets are so so.
Wow I can't believe how bright these lights are. I was amazed and for the price you can't beat them.
Worked fine once I switched the wires.
Answer: no
