I just received the re-chargeable CR2 batteries to put into my DX200.
One heck of a difference. With standard fresh Panasonic Lithium CR2s I got
160mW and with the charged UltraFire CR2s I got 203mW.
The type of batteries and voltage do make a big difference.
I would definitely only use the UltraFire batteries with the DX200. [smiley=thumbsup.gif]
If you plan on plugging your diode directly into a mag lite (like in the KipKay or whatever video) you'll be wasting your time and money. It may work for a little while but it wont last long without a driver to regulate the current. If you wanna build one yourself, I suggest reading the DIY MXDL & Dorcy threads in the Experiments and Modifications forum. Otherwise you'd be better off buying the DX200.
Lighting matches instantly up to 6ft holding the laser in hand(even the safety matches which wouldn't burn with my X85)
Farthest balloon pop about 24ft
Burning through cd case within 5 seconds (like the one on youtube)
Unfortunately I cannot do any other experiments until my goggles arrive.(so it's a little hard to look at the dot to focus)
Furthermore I ordered the recharcheable CR2's and charger from DX but still waiting for supplier.
So all tests were done with Panasonic Lithiun CR2's (anyone knows the estimated lifetime of these batteries?)
So I guess with the rechargeables and the goggles(for better focussing) the results will improve.
