    Maxa Beam enhanced reflector option. Anyone have one?

    Here is a graph that compares many different coating reflectances. Some of you may find it interesting/usefull, it includes enhanced rhodium and aluminium. I found it on optiforms website, these are coatings that can be applied to their electroformed reflectors...

    Reflectors for XM-L?

    The 27mm IMS reflectors throw a lot better than the 20mm, but as said three wont fit in a mag head and they require some sanding down to avoid a donut. You can fit up to 4, 20mm reflectors in a maglight head. An XM-L with a 20mm reflector will be floody, if you want better throw only use only...

    Maxa Beam enhanced reflector option. Anyone have one?

    Thanks for that Annie, much appreciated. Sorry for assuming it was aluminium. Sounds like that coating has both the advantages of aluminium and rhodium! Does anyone else have an estimate as to how long an aluminium coated reflector would last under a Xenon short arc lamp or similar. Thanks

    Maxa Beam enhanced reflector option. Anyone have one?

    The new aluminium coated reflectors should actually be significantly cheaper than the old rhodium reflectors, as rhodium is a very rare precious metal, apparently worth between 5 and 25 times more than gold! So the change is probably to make more money while increasing the proformance for a...

    Maxa Beam enhanced reflector option. Anyone have one?

    Out of interest, how do the new aluminium coated reflectors hold up over time to the high levels of uv that the bulb produces? I have heard that aluminium reflectors degrade faster than rhodium coated reflectors, but I don't know if the difference is that significant. Thanks

    4D mag HID Drop in available?

    As Chrontius said there are no specific HID dropins. The Ushio (previously Welch-Allyn) solarc HID lamp and ballast is the only one that will fit in a maglite. The ballast is about 1mm too wide to fit in the maglite body so maglite must eather be sanded/boared about 1mm wider or the ballast...

    Ground up sst-90 build (now with a fun update!)

    Re: Ground up sst-90 build That is one beautiful light :) I can see why it took 60 hours to make, you are very skilled. But a light like that should really be regulated (in my opinion). Edit: Just found out that it is regulated, sorry for the false assumption (the pictures must have...

    Beamshots: Stanley 35W HID, S250 35W HID, 400W HID Thor, Supernova, DEFT, Tiablo A9

    Great beamshots:) Does the thor s250 have a glass or plastic lens and what is the diameter of the reflector (5")? It looks like it will be a good, cheap host for some future modding :). Thanks for any answer as I know this thread is relatively old.

    Just started a dental flashlight project

    I have just noticed that luxeon has brought out a new rebel ES (LXW8-PW50), it has a colour temperature of 5000k, it has a cri of 85 and an efficiency 110 lumens/watt. But since it has a larger die (same size as an xp-g) it will have produce slightly wider beam (1.4 times wider). You will have...

    Move over SureFire, there is a new Beast in Town! ~500,000 lux@ 1 meter

    Re: Move over SureFire, there is a new Beast in Town! So... what do I win :) Looks like it will be a really powerful light when finished and it will still be relatively portable. Sorry if I ruined your fun:nana:

    Move over SureFire, there is a new Beast in Town! ~500,000 lux@ 1 meter

    Re: Move over SureFire, there is a new Beast in Town! I'm going to take another guess and say that it uses an UHP projector bulb (possibly that 50w one) powered by a 50w HID ballast like in those experements you were doing earlier.

    Move over SureFire, there is a new Beast in Town! ~500,000 lux@ 1 meter

    Re: Move over SureFire, there is a new Beast in Town! looks nice:) I see you have attached the Night hunter II head onto a mag. I'm guessing a 35w HID mod used with the night hunters high quality reflector for amazing throw (if a ballast fits).

    14w HID Maglite super thrower 330,000 lux!

    Re: 14w HID Maglite super thrower Thanks Apparently photobucket is "experiencing some maintenance issues which affect a small percentage of our users" they say the pictures should be working soon. Edit: The pictures are working now.:)

    Just started a dental flashlight project

    Have you looked at the lxm3-pw51 rebel LED? It has a relatively high CRI of 85 and has a very nice neutral white tint of 4000k, it will work with the optic to produce an 8 degree beam and can be used on the same pcb board, its only slight downside is it is slightly less efficiant than the best...
