wymberley Posted April 21, 2011 Report Share Posted April 21, 2011 Had an idiotic accident so was looking for replacement bulb plus spare for the 170. Not bought any for years so the price from the normal shooting kit supplier was a surprise. Shopping around I discovered why I like Osram. Some time ago a thread suggested that you can get 100 watt bulbs of other brand names cheaper (the OP expressly was asking for the source of the Osram Pt. No.). The difference in performance surprised me when I found that Osram put out 2800 lumens but Philips (hardly rubbish) 2150. Got 2 for less than £13 inc postage at Bulbs Direct. The shooting kit supplier wanted £10+ per bulb. PS Have no doubts that someone can get them for £2 19 11 inc postage. Quote Link to comment Share on other sites More sharing options...
Alycidon Posted April 21, 2011 Report Share Posted April 21, 2011 (edited) Osram do an automotive version of the bulb with a horizonatal filement, works ok, far cheaper but use in 170s only I would suggest. For a long reach 240 though the tighter beam found with the vertical filement is better. Part no is below in Wymberleys post. Osram 64265 is I think the number of the tighter beamed bulb but that might be wrong as I have a stock of both (64265 + 62138) types. It is a dedicated spotlamp bulb and not an automotive standard H3. H1 or anything else with an H prefix. When you fit it use gloves to keep the grease on your skin form the glass, it will cause premature burn out. The other thing is do not push the bulb all the way in, the optimum position is about half way in, there is a black mark on the two pins that ends half way up, thats as far as it needs to go. then adjust the lens on the thread to give you the beam you want. With thanks to Wyberley keeping me on the straight and narrow. A Edited April 22, 2011 by Alycidon Quote Link to comment Share on other sites More sharing options...

Just for info, the correct terms are "axial" and "transverse" respectively. Quote Link to comment Share on other sites More sharing options...
Colster Posted April 22, 2011 Report Share Posted April 22, 2011 Never having owned a Lightforce, excuse my ignorance but are these H3 bulbs you're talking about. I have two lamps for use in the car, one is a Deben Cyclops and the other I have no idea but both use an H3 bulb. I've seen them for sale on eBay for £3.00 for a 100W Xenon filled one. These are the non-road legal ones (not a problem for what we want them for) and they get sold as singles too. Quote Link to comment Share on other sites More sharing options...

These have 2 pins and plug in directly. Cheers Quote Link to comment Share on other sites More sharing options...

The 100w versions of these bulbs produce more light yes but they also produce a lot more heat, that heat may melt your lamp unless it is designed for it. It also wont run through a lighter socket as the amperage (think voltage volume) is to high, your lighter socket will again melt. Use a dedicated DIN plug and socket, these will handle up to 17 amps constantly ( 12v on a 100w bulb uses just over 8 amps) A Edited April 22, 2011 by Alycidon Quote Link to comment Share on other sites More sharing options...

I've cut that off and fitted a "lawnmower" two pin plug to it, the other end is wired directly to the battery. Quote Link to comment Share on other sites More sharing options...
wymberley Posted April 26, 2011 Author Report Share Posted April 26, 2011 Oh dear! Not so clever after all. Lamps arrived. I specifically asked for Osram, giving the spec. and Pt. No. The delivery note said they were Philips but the actual contents were GE. Waiting for a reply to my comment! Quote Link to comment Share on other sites More sharing options...

wymberley Posted April 26, 2011 Author Report Share Posted April 26, 2011 I'm using GE bulbs in my 170... without issue. The only issue is that I, quite rightly I think, expect to get what I paid for. There was no problem with the order when I placed it. Why so fussy? Osram 2800 lumens and GE 1950 for the same price. You pays your money and takes your choice - or sadly not in this case! Quote Link to comment Share on other sites More sharing options...
garyb Posted April 26, 2011 Report Share Posted April 26, 2011 Agreed... Like you I didn't want to give Deben silly money either for replacement bulbs. Luckily I have 4 new bulbs, yet I only ever paid for 2 - Result Quote Link to comment Share on other sites More sharing options...

I would imagine that if one were to let it be known that there was a requirement you'd probably hear from him. Quote Link to comment Share on other sites More sharing options...
wymberley Posted May 16, 2011 Author Report Share Posted May 16, 2011 Not withstanding our man on here, but I like to be fair if possible. It seems that the bank holiday periods coupled with a change in Bulbs Direct's location caught me out. Once I had explained why I specifically wanted what I ordered and the returned bulbs had been received at the new via the old location, the Osram units were immediately dispatched and I got them 1st thing today. Fair dos! Quote Link to comment Share on other sites More sharing options...
Frenchieboy Posted May 16, 2011 Report Share Posted May 16, 2011 I have been through this thread as I have a Lightforce 140 and want to buy a spare bulb for it rather than get caught out with no spare - We all know that it is s0ds law that it is when you don't have a spare that is when the bulb is most likely to blow! Please can someone clarify which is the Osram Part Number for the bulb that is best suited for the Light Force 140 to give the tightest beam possible please?
