Shopping locally in Australia for a new spotlight/host for projects, I have been debating between two local companies biggest reflectored units. The LightForce (LF) Blitz 240 is well known by many on cpf, but does anyone use, or have experience with the Powa-Beam (PB) brand manufactured NSW Australia?.
........................Diameter(cm).....Area*(cm^2)...Cost(Aus$)...CP'
Lightforce...240 ......22.5 iirc..........397................ 150......... 1M
Powa-Beam...265 ....26.5.............. 551 ................250.........1.37M
*Assuming perfect parabola without cutout for bulb mount to calculate
' Using short life halogen globe (factory spec LF axial, and scaled Area ratio for PB CP). Note: PB claim 1.45M and uses transverse filament)
The PB website (although very lacking in info) states a 12" version is available. Does anyone know of a larger variant than the 265mm (labelled 11"). There appears to be 2 variants of the 265 PB, possibly one newer, one older. Both have an external metal shell completely encapsulating/sealing the spotlight. One has a plain metallic outer (possibly ss) and a glass lense (higher weight, possible 2kg), the other having a grey/purple coated shell with plastic lense (just over 1kg). Changing globes is only possible through the front with lens removal. The outer shell is one piece. A rubber gasket appears bonded into place holding/isolating the lense to/from the outer shell. Does anybody have experience with this system. Does it require breaking the bond between gasket and shell then rebonding? A recessed groove runs the perimeter indicating a possible press-fit??. Please help if you can. All PB spotlights 110-265mm have same construction. Please note the 265 model is designed as a vehicle mount light, but a handle could be attatched to the mount bracket relatively easily.
Given the size and calculated (relative max CP) the obvious benefit to any modder of the Powa-Beam is a max Candlepower almost 40% greater, along with glass lense (on heavier version) and metal reflector for thermal characteristics (I assume less likely to melt with High Power Mods). Please chime in if experienced. However the user-friendliness of the LightForce is far superior. Bulb change by unscrewing reflector unit no tools. Lower weight (650g). Spreadable beam. Corrosion resistant Plastic/composite shell and reflector. The PB being car mount design offers user option to change between handheld and car mount, where LF is handheld only. Finally I would tentatively say on inspection, the Powa-Beam has a smoother, more polished and perfect looking reflector, although the larger size may give this illusion.
If passing a local gunshop in Aus, please check in and have a look for these. I'm wondering would you take one over the LightForce?
Finally, Does anyone have a source of large reflectors, in australia, or overseas at reasonable/similar budget?
Any questions, comments, chat and HELP welcome
