Author Topic: Helios Slimline Xenon Bulbs Steve Wilson Expert Film Handler Posts: 109 From: Paoli, IN, USA Registered: May 2004 posted 02-16-2005 08:08 PM                        Does anyone have any experience with the new LTI Helios Lamps. It is a slim line envelope that allows more light to pass by the envelope to allow one third more light that normal bulbs at the same rating. Thanks Guys.  |  IP: Logged Chris Hipp Phenomenal Film Handler Posts: 1462 From: Mesquite, Tx (east of Dallas) Registered: Jul 2003 posted 02-16-2005 08:30 PM                     I used to use them. They will give you more light, but dont be fooled by the wattage rating. They still pull the same amps as a 7k bulb. We used them because they claimed that they would be easier on the lamphouses (strong highlight II.) Perhaps someone else can give you a more technical answer. I did get many more hours out of them than the rest of the LTI bulbs.  |  IP: Logged Steve Wilson Expert Film Handler Posts: 109 From: Paoli, IN, USA Registered: May 2004 posted 02-20-2005 11:12 AM                        Thanks Chris for your reply. I was hopeing more would chime in on this bulb. I have a 2000 watt set up on my 66 foot screen and I was hoping to get a tad bit more light to help me out a couple of seasons until I can make some money to do something else. I am also limited to single phase! Anyone out there have anymore to add about this slime line bulb!  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 02-20-2005 11:41 AM                     For a 66'screen one needs more tha 2K I would think about the strong switcher powersupply as it can do 3K on single phase Also if one designs it properly 2 2K rectifiers can be parralled to supply 4K  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 02-20-2005 12:24 PM                     quote: Gordon McLeod Also if one designs it properly 2 2K rectifiers can be parralled to supply 4K E-Mail the "Mighty Phil" on how to do this.....

Lauderdale, FL, USA Registered: Jun 2001 posted 02-20-2005 02:03 PM                     L.P. Associates have supplied me two conventional magnetic type 2kw rectifiers sharing the load to supply a 4 kw lamphouse. Each rectifier had a input power variac and meters installed on the power supplies to balance the load. There are single phase switchers now available to handle 3.5 - 4KW from other companies other than Strong.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 02-20-2005 03:11 PM                     Richard, do tell! (Phil, you too. I am quite interested in that.)  |  IP: Logged Steve Wilson Expert Film Handler Posts: 109 From: Paoli, IN, USA Registered: May 2004 posted 02-20-2005 05:17 PM                        Money, if Money was no object, oh well. All of this info is good and I am sure that I will at sometime use it, but for the time being I am stuck! I am only 178 feet from the screen, does this make a differnce? We have had this argument that distances are not that cirtical on light, but as a photographer, I know better! Since I am close, I would think, that would help. I am trying anything that I can to put just a little more light on this screen, a new bulb is due and this is not an added expense. I also, usually self circuit Drive In prints from a Drive in 5o miles away. Buy the way, at 40x66 at 178 feet, how much light do I need to light a screen this size  |  IP: Logged Barry Floyd Phenomenal Film Handler Posts: 1079 From: Lebanon, Tennessee, USA Registered: Mar 2000 posted 02-20-2005 11:28 PM                        Hey Steve.. The dual 2k rectifier setup does actually work. The Swan Drive-In in Blueridge, Georgia has that setup because of the lack of 3 phase. Good to see you finally on Film-Tech  |  IP: Logged Steve Wilson Expert Film Handler Posts: 109 From: Paoli, IN, USA Registered: May 2004 posted 02-20-2005 11:58 PM                        Thanks Barry  |  IP: Logged Phil Hill I love my cootie bug Posts: 7595 From: Hollywood, CA USA Registered: Mar 2000 posted 02-21-2005 12:00 AM                  JFC!
