Welcome aggillztor! I’m also from Houston! 
Someone recently posted about how they modded their SRK: [MOD] SRK-43 aka "Poor man's Meteor"
There’s lots of problems with all SRKs that prevent it from reaching it’s glorious luminous potential, and these problems have to be fixed.
I’m almost certain that it has fake cree LEDs. Those have to be changed for real crees. The difference between the real and fake cree is in thousands of lumens. Tint is also greatly improved.
Here’s a post on them to give you more info: - The Fake-Cree LED Awareness Thread - The new "low" in Budget lights.
Those LEDs sit on something called a MCPCB, and it’s made out of aluminum in your SRK. To really get the light going you need those LEDs to sit on copper to be able to transfer the heat away effectively.
That MCPCB needs to sit on a shelf inside the light that will transfer the heat away from the LEDs/MCPCB, to the light body itself. SRK’s have been lacking this shelf lately, so its probable that yours does also. A shelf/heatsink needs to be created and put into the light in a way to properly distribute the heat.
A new driver is needed to power the LEDs to their max potential.
I don’t have a SRK, but that’s what I’ve gotten from other’s who have modded their lights and posted about it.
If you want a light that’s already incredibly bright and really affordable, this is the best place to find it.
