Cyclops 18M cd flashlight Mod

I stumbled across this cheap light at $62.99 on Amazon and after some research, decided to get it for fun and mod it.
It has been on the market for 10yrs and nobody I could find has tried to upgrade it in a very long time.
So here is some pics BEFORE modding with beam shots and stats to compare later.
It advertises 18 million cd and 30 minute runtime.
2 × 6V rechargeable sealed lead acid batteries in series for 12V output.
HALOGEN BULB: Philips 130/100 watt.
.
Actual readings, LOL were less than advertised below.
2000 Lumens
200,000 cd

This automotive led will be going in. I am not convinced it will be much better but the runtime should be.

Are those new LED headlights the kind with an itty bitty fan on the back/bottom? I wonder if a 92 or 120mm PC case fan could be modded on there to keep the interior cool.

I bought one of those Cyclops spot lights when they were being blown out the doors of the local big box Costco store around 2007.

Decent reflector but the only way to get the stock bulb to sing was to add a switchable inline 3.6 volt booster battery made from high current RC battery pack NiMH cells.
Only then was the overdriven bulbs output decent for the first 5 minutes or so.
Looking forward to hearing how runtime with the led conversion bulb is.

Large reflectors have a huge advantage if they are of sufficient quality and well focused. But the cheap ones take away a huge amount of performance potential. After several builds, I finally settled on a 100 watt HID. This one reaches far past the 3000’ runway I use as my test range. Fun stuff that still gets used regularly…

Yes, a 60mm fan is going on the bottom, just below the led. The light has vent slots built in already. Beer
