jexjexjex Posted December 15, 2013 Share Posted December 15, 2013 Hi Troops, I may have asked this before, but does anyone know if T13 (P28 base) type lamps are available at less than 650 Watts (Preferably something less than 500 Watts?) I've had a look and can't seem to find any, but maybe some of you might know... Link to comment Share on other sites More sharing options...
mal421 Posted December 15, 2013 Share Posted December 15, 2013 They are or have been in the past. I have 1 rated at 50w but have no idea if they are still available. Link to comment Share on other sites More sharing options...
mikelx Posted December 15, 2013 Share Posted December 15, 2013 Old P28 base lamps for Patt 23 etc were T/1 500w and T/3 250watt in the days before Tungsten HalogenI don't know whether they ever made a T/3 equivalent in Tungsten Halogen Link to comment Share on other sites More sharing options...
danburns Posted December 15, 2013 Share Posted December 15, 2013 http://www.bltdirect.com/2250c-navigation-lamp-65-watt-p28s - 60W @220-240v (Can't vouch for the company as I found them after a quick google) Not sure if that helps? Link to comment Share on other sites More sharing options...

mikelx Posted December 15, 2013 Share Posted December 15, 2013 That 65watt looks interesting! The filament may not line up optically. jexjexjex What lantern is it intended for? Are you just trying to reduce output? Link to comment Share on other sites More sharing options...
Jivemaster Posted December 15, 2013 Share Posted December 15, 2013 Yes I remember the 250w P28 lamps as big round globes. No I haven't seen one for (30 ish) YEARS Link to comment Share on other sites More sharing options...
jexjexjex Posted December 16, 2013 Author Share Posted December 16, 2013 That 65watt looks interesting! The filament may not line up optically. jexjexjex What lantern is it intended for? Are you just trying to reduce output? The lamps are to go into a set pf four Patt.803s in a local church. For all the faults of the 803, they're fine for what they're being used for- just VERY bright, so I figured that something around the 300 watt mark might might help things and it would save me having to strip out the lamp bases and replace them. Thanks for the responses so far. Link to comment Share on other sites More sharing options...
pumphouse Posted December 16, 2013 Share Posted December 16, 2013 you may find that the costs of sourcing the older lamp types (especially over a period of time) far exceeds the costs of changing the lamp bases to take something more modern with a cheaper (and more available) lamp.

mikelx Posted December 16, 2013 Share Posted December 16, 2013 If you want to reduce output why not put them on a dimmer circuit? I agree that the cost of the lamps or even putting in different lampholders maybe too expensive.and the 60 watt lamps are not going to give much output at all.
