    Yes, but this is definitive light bulb replacement thread. The Heiland is king, but more of a retrofit than a replacement.

    Re: Definitive LED / Incandescent enlarger light bulb replacement thread

    I'll throw this out for anyone interested and I have no business agreement with the specific company. I've been looking for alternative bulbs for my condenser head, mainly LED types. And it was becoming very difficult to find anything that filled all the check points that the bulb should have.

    I was searching for replacement PH212, PH211 bulbs and I happen to stumble across this company that has 75W and 150W LED bulbs that are fully glass bulbs without the usual LED plastic neck on the bulb. Most interesting is the company claims they are halogen bulb matched at 3000K which are what the PH212 bulbs Kelvin temps are. The bulbs are listed as " LED bulb in milky white -Color 3000K ".

    The LED 15W is equivalent to 150 W normal bulb. So I ordered two and can confirm that they are a total glass envelope and are opal milky white in appearance and seem to be a PH212 bulb with an LED inside. More important is that near the base is some labeling that can be rubbed off with a little effort leaving a totally white glass bulb like the PH212 bulb. I haven't tried these yet with a step wedge but I can confirm they are instant on so they appear not to have any start up time lag AFAICT.

    The company is LampsPlus.com and part number was 76H29. Based on three hours per day, estimated life is 22 years for the LED bulb.

    Use heat absorbing glass (if you are using tungsten lamps) followed by a good diffusion material. Opal glass is a good diffuser, but also quite opaque. It absorbs a lot of the light (more than a stop). This is true of white plexiglass, too. There are new diffusion materials available that are over 90% transparent. Depending on your diffusion requirements, you may need a double diffuser. Best to do this with one close to the source and then one as the top cover for the negative holder. This also eliminates all Newton rings without special anti Newton glass.

    Double diffusion is a very powerful tool.

    This light and associated technology could mean big changes in the industry if it works as claimed. Public demonstration on Nov. 25th. It may go open source.

    Until I was able to obtain a Modern Enlarger Lamp LED head for my D5, I used this 150W halogen bulb: Q150FR. It gives a sharper image (smaller light source, starting to approximate a point source) but it also generates a bit of heat, so you need a heat-absorbing glass or a glass negative carrier. These are no longer available in California, but I had stocked up on them--PM me if you are interested in acquiring a couple.

    No Vincent's but I knew the boys in the local club, too expensive and often stolen

    3 Commandos, 2 Norton Electra, 1 Matchless G15 CSR, my favorite as it was my first restoration, sold it to a guy who totaled it...
