I am going to comment on the $20 XENON lights at SAMS. I do not have, nor have seens, the Luxeon models.
First - before there is any more confusion - the light at SAMS is not on the web page linked earlier. Those are all high intensity LED's, hence their cost. This is a lower cost Xenon bulb, which has higher light output with much worse battery life than LED.
First - here is a pic to compare the Cyclops with a Surefire G2 and 6P:
Yes - I am aware I have not removed the wanring sticker on the cyclops:
Whoever said you could use a Surefire P60 bulb doesnt own one. These are NOT a copy and they are NOT interchangeable:
Whoever was asking about el-cheap weaponlinghts.... the cheap surefite tailcaps are NOT interchangeable.... the surefire body has threads on the OD, this light has threads on the ID, and the tubes are the wrong size:
Lastly - about ring size....
Surefire 6P OD: 1.008"
Surefire G2 OD: 1.020"
Sams Cyclops OD: 0.866"
You cannot use a 1" ring for these like you can for a surefire. This tube appears to be between 13/16" and 7/8".
I did not feel the beam was as pure nor as bright on this Cyclops as my surefires are. Not even close to what the previous pics show in this thread. This tells me the QC from batch to batch varies.
Since the Surefire is rated at 65 lumens... and this isnt as bright, someone is stretching the truth, and my guess is it aint surefire. It is what it is - a damned bright, handy, aluminum body light, for $10.
Good deal, IMHO. I bought 4. 2 for a gift and 2 for me. Can't ever have enough lights.
