CBT-90 at 2362 Real OTF lumens = VARA2000 Frankenlight

[bigchelis]

Hi all,

Kevin from Lambdalights sent me a cool light. It might or might not be offered to the public, but it uses a cool CBT-90 65K tint.

Things about the CBT-90:

• Its essentially a SST-90, but domeFree from the factory
• uses a copper star that looks 50% taller the the aluminum SSR-90 one
• It naturally has a throw type beam that should do 90k plus lux at 1m. I still have to test this.

The Frankenlight:

• A 2in Copper slug heatsink was used
• The 3D Mag was extended to accomodate the huge heatsink
• Still uses the VARA2000 control knob
• The cells go backwards
• The light is heavy, but most spot lights are and the added weight still makes a featherweight compared to the less bright SST-90 searchlights in its category like the SR90 at 1480 OTF and 95k lux.

Here are pictures of it, but I still have to wait for night time to do beamshoots.

Mama mia. That's one hell of a bright light. .
And the battery configuration is the same as those laser pointer pen. .

So is this OTF numbers for the SST-90 light or the CBT-90 light? I'm guessing it's the CBT-90, and you accidentally made a typo? If so, the lumens aren't much higher than the SST-90 copper version at 1 sec, and it actually makes less OTF than the SST-90 copper version made before it reaches the 30 second mark. The CBT-90 must be an inefficient emitter.

correct, I meant to put CBT-90:wave:

The Domeless SST type emitters make considerably less OTF numbers when I dedome them, but this one makes just about the same as the domed counterpart.

I get 3,900 lux at 5 meters.


It is 97,500 lux at 1M


So, its nearly 1000 more OTF lumens then the SR90, lighter, alot less expensive, and more throw. I think this VARAPower Frankenlight should be made for the public cause its a good searchlight.

I will try and get beamshoots soon.

BOOOOOYYYAAAAH!!

LEDs with 100k lux (almost) and over 2000 lumen.


its gettin crazy in here..


KEEP IT UP!:thumbsup:
