Second attempt to post. A little over a year ago Controlbooth members asked about a new Fresnel lamp that would match up with modern Lekos. I presented the idea amongst others to some lamp companies and the Osram reps. took that project on. Last night I answered a message from a guest contact about him hearing this lamp existed and I carefully said it was on the way in not mentioning brands but was not on the market yet. Today I checked last week's PLSN product of the week and noted that the lamp asked for the BTH was just introduced at USITT 2008 and is now available. The product managers at Osram that asked me not to anounce until it came to market seemingly got a bit busy at the last minute and forgot to tell me the lamp that was late in coming was now on the market. This much less my sample lamps were now on the way once contacting them about that. Anyway, it's out, the lamps are available now. Saw the prototype for the lamp a few months ago and its going to set the world on fire. Due to market share needs for the company that got it done, I couldn't more than hint about it until now but it's a great lamp and long in coming. In noting the specs today, the only thing I noted about the lamp was it's base down to horizontal burning position, but on the other hand in a normal 65Q type fixture I would be more worried about a gel frame falling out of the fixture if other than that angle anyway. Still interesting that the GLC lamp this is based off of and even EGE are any burn position, this one is not and more similar to a BTL in that way. None the less, you get the matching color temperature, higher output for that voltage in being a high output 575w lamp. As noted if you want a long life version, stick with the BTL in that a GLA version would not gain much in efficiency over that of the BTL. Not quite as bright as a BTN 750w lamp, but higher color temperature than them all which will be important in seeming that way and in getting light seen on stage yet for less wattage. Good lamp, give it a try if wanting more output and can afford the 300hr/115v verses 2,000hr/120v difference between them or for even a top hat down light you want that glowing look. I see tremendous value in this lamp thus why I passed this great idea off this website onto the manufacturers. One manufacturer took Controlbooth up on that idea. This and I finally convinced one of my mentors/home stage TD's to play test the HPR Leko lamp for his 575w house. Again high output and a great lamp. If you want gobo accuracy, go GLC in theory because the HPR 575/115v lamp does them well also, but for overall beam of light - flat field that in a well bench focused 360Q you can out-punch a S-4 fixture, the HPR is much more fogiving a beam and more intense and better. This much less in a Shakesphere or other more optically modern fixture what it can do. Two lamps for high output I highly recommend in making the most of what they can for the reletive efficiencies of the fixtures they are installed in. Sub-note in chat, Will the new BTH out punch a ParNel? Answer is no persay in testing. The ParNel is more optically efficient. Hard to make the reflector of a Fresnel more efficient in putting out the light. ON the other hand for cost of fixture pricing, will it be more cost effective especially if you already own the normal Fresnel.... Yep, and it's gonna change your world. Hope it helps - it's out there now, you asked and got it.
