I added SHEERVISION's Original FireFly Portable LED to the test and guess what? They kicked butt!
They are as bright as the big boys (Orascoptic and DFV). They have a wide field of vision like Orascoptic. Overtime I had a problem with the DFV's narrow beam. I was constantly fiddling with my glasses to keep the light on the correct area. If my glasses moved slightly I had to reach up and adjust them to get the light back on the correct area. This got real annoying. The Orascoptic and the SheerVision have wider beams which negate this problem.
The SheerVision battery is Nickel Metal Halide like Orascoptic's but they give you two batteries unlike Orascoptic, which is a plus. I needed two batteries with every one I tried. Orascoptic says that one is enough but my light got obviously duller by 3 PM. Two batteries are essential and SheerVision and DFV give you two and Orascoptic gives only one. If you ever need a new battery the Orascoptic replacement is $525! DFV is $325! The SheerVision replacement is only $75**!!! Nuff said about that. They all claim that their batteries last a couple of years. |

Here is the best part.
The cost on SheerVision's website is $695* which is way less than either DFV or Orascoptic. That includes 2 batteries, charger, mount, light, everything!
To recap, Sheervison's portable light quality is exactly the same as the others. They all are equally bright. SheerVision has a larger field of vision than the DFV. SheerVision has two batteries instead of Orascoptic's one. SheerVision's NiMH replacement batteries are only $75**. SheerVision is much less money.
I returned both my Orascoptics and DFV's. If SheerVision's quality was not as good, I would not have.
We now have a clear winner in the comparison test.
* Effective 12/1/2006 - SV
**PLEASE NOTE - NiMH battery packs are no longer available. They have been replaced by the new Ultra Battery Pack - with Lithium-Polymer technology (MSRP $275.00).
