    Precise information of the new cold light sources with LEDs I even do not have from Heiland. I only know he's building them on request in very small series for 35mm, 6x9cm and 4x5" and even larger, enlarging systems since a few months.
    Existing customers have always the possibility to upgrade their system with the cold light source unit only.

    The additional Comfort module gets the power and communication via the RS232 cable which is suplied already with the Console and normally only used to retrieve the new software version (actual V2,4) from the computer to the Heiland Console.
    A new version is expected soon (V2,5) hopefully now with some pre-programmed Foma papers.
    According to the Heiland website the SPL-CL1/2/3 include the "Controller, probe, foot switch, cables" (part 1) and "Heiland LED cold light source and adapter" (part 6), which implies that they include the cold light head. Probably, some adapter is needed to fit it to a specific enlarger (?).

    If you equip your enlarger with a dichroic color head, you'll be able to use the Heiland Splitgrade system in the "manual" mode and save some money; all you need is the Splitgrade Controller with the probe (and footswitch if desired). You'll be amazed at the speed with which you'll produce acceptable prints eg snapshots- for perfect "fine" prints you need some experience/practice with the set-up.

    You don't need the Heiland enlarger light source/filter unit right away, nor the Comfort interface. Unless that's what you're after from the start.

    When using the dichroic head you probe the high resp low density areas of the projected negative, and the Splitgrade Controller will tell you to dial in the resp filters; it functions as enlarging timer as well, setting a different time for each filter and in doing so achieving the right contrast for your chosen VC paper.

    Can the LED cold light source be used with a Beseler 45 VXL or 45 MXT enlarger?

    Does it have both blue and green channels in addition to the red?

    What is the price in US dollars?

    Is it comaptable with 120V and an RH Designs StopClock Pro timer?

    Thanks.

    Yes, the adapter is customer made for each different enlarger, that's one of the reasons the price is pretty high.

    But you can also order the cold light source seperately. The same is valid for the Console only where you can do Split Grade manually. Price: Eur. 824,00 (19% VAT included for Europe).

    SPL-B1: Split Grade for Beseler 45 (1+3) for Eur. 1300,00 is available so I expect also the cold light source must be possible then. For this enlarger a complete rebuild of the HLX colorhead is necessary. For the cold light I have no idea. You should e-mail Jürgen Heiland for that. I know Split Grade is available also for 115-120V/60Hz.

    The complete prices for the cold light systems incl. the Split Grade Console are as follows:
    SPL-CL1 (35mm): Eur. 1400,00
    SPL-CL2 (6x9cm): Eur. 1643,00
    SPL-CL3 (4x5" ) : Eur. 2000,00

    (19% VAT included).

    In case of a rebuild system (1+3) you have to sent in the color head to Wetzlar in Germany.

    Most flexible are the modular type enlargers where (1+2) means that the customer can do the changing to Split Grade themself. Dunco II 66/67; Durst Modular 70; Jobo/LPL 4x5"; Kienzle A35/T67/T69 ; Kaiser Sys V ; Leitz V35; you can do yourself.
    1+5 menas an extra adapter and transformer also possible to install by the customer:
    Agfa Varioscope; Ahel 12; Durst M700 kond. ; Leitz 1C/2C.

    All other enlargers needed upgrade/rebuild unless you decide for manual Split Grade. Later on you can always go for a full auto system or the upgrade to the cold light source.

    Best regards,

    Robert

    This is the latest info I have received from the cold light source. You can use this type also on condensor systems only:
    ++++++++++++++++
    Do you want a Splitgrade system but your enlarger is
    not yet supported? Are you happy with your enlarger
    and don't want to change it? Maybe it's an older
    condenser enlarger but still working well. Or are you
    unhappy about losing the ability to print colour after
    modifying a colour head to work with the Splitgrade
    system?
    Here is our solution: Simply replace the complete light
    source of your enlarger with our brand new cold light
    source. This works independently of your existing light
    source type, even a condenser enlarger can be
    equipped with the latest modern Heiland cold light
    source.
    Instead of the usual neon tubes, our system uses hundreds of super bright LEDīs in 3 colours
    (blue, green and red) leading to several advantages like
    • No light drift – stable light from the first millisecond of exposure.
    • Near white light for focussing purposes
    • Insensitive to mechanical shock
    • Can be adapted in size to your invividual enlarger
    • Emits paper safe red light to target burn in areas
    With only 25% of the power consumption of traditional halogen tungsten light sources, our light
    source produces an equivalent light intensity. No fan is needed.
    The light falloff in the corners of the negative is eliminated with our light source. The life time of
    the LEDīs is several thousand hours, no replacement of LEDīs is expected.
    The cold light source is controlled directly by the Splitgrade controller; existing controllers can
    be used by simply updating the software.
    We adapt the size of the light source for your existing enlarger, at the moment we offer three
    sizes for
    • 35mm negatives
    • up to 6x9 negatives
    • up to 4x5 inch negatives
    Other sizes could be produced on demand – please contact us.
    +++++++++++++++++++++++
