“For pic 5:
FCM; 4x FDB; EHD,EHG or EHF; and what looks like maybe DPW, but I don't think it is the same. Looks similar though.
Next row:
2x
HMI 1200(?); and maybe an EVR or Q250E14? Hard to tell really.”
Q250E14??? what are you writing your own lamp codes now or is it a trick question? I'm aware of only one Europian screw based lamp at 250w and it's proper description would be Q250CL/E14. Very rare lamp and not a common one that could either be it or the E-11 based EVR above. More common to name amongst many wattage in this lamp
base type would be something like a Q250/MC. Still good effort in figuring it out.
Ah’ someone brave enough to take the challenge! Much less that studied some into lamps!
Your scale is a
bit off given the #4 lamp is most likely in un expanded form either a T-3 or T-4 in
bulb size. Given a FDB is 6.9/16" long and 1.5Kw, it’s unlikely given if it has a T-4
bulb size, than this being out of scale does not work once you note
bulb #4's size as opposed to the rest of the double ended lamps in length. T-4 = ½" in dia. Also, most lamps are for use in common equipment so expect that the bulk of bad ones will be simple to figure out.
I should hint that most of the lamps above have a 4.9/16"
MOL otherwise and were found in
Altman or
Colortran Ground Cyc fixtures.
This is on the other
hand is a EHG lamp, and good guess in scaling it’s T-5 or T-6
bulb dia. Verses that of a defiantly T-6 or T-8 FEL or FLK which are possibly slightly longer in
MOL.
Good guess on the DPW!!!. Nope, this was a 1.5Kw lamp, but still good guess. What lamp(s) could it than be? Take it for a given that if it could be a DPW, than the user probably wanted to maximize the life for output. This should hone you in. Forget what
fixture it’s used on if you want extra credit, but I assure myself of being lucky in retaining this lamp once I got the customer his replacement. I neither stocked replacements, nor had ever seen this specific
bulb before. Talk about seeing things in a
bulb image.... anyone see a standard KilRoy was there shape to the opposing end of the
filament shooting out of the glass here in other photos?
This sucking in of the opposing side of the in this case a
incandescent lamp is what you would see also in a
halogen lamp given the same type of glass used as a very similar and important example of what's going on here to the first of this question's lamp. Note in both instances the
filament size hole in the glass forming a hole around it as if a bullet shot
thru the lamp and the glass held to it's after effects. Given the vioence of such an action, one shoud be assured that the warming effects of touching a
bulb would not have the same
effect. Much less given the soft lime glass of the second example of the
incandescent lamp, you can touch it as much as you want and the oil from your fingers won't
effect the lamp. This is important to know about as otherwise an observation others earlier built upon as a standard problem possibly in this photo shown to be the cause otherwise.
HMI 1200 as my most favorite game I
play with techies looking for lamps, limits the lamp to one of five choices including the
PAR 64 version by the description you gave. Normally I say one of about 12 in necessitating the tech person walks back up stairs and figures out what lamp they want, but in actuality there is only five versions of this. Such a walk to figure out what they want helps to solve the below problem in the field, much less offers me more time to finish working on what I’m doing.
A hint is that it’s both a common lamp on high technology gear and that it’s name is about to change to an even harder one to remember. If you are hanging upside down on a
truss in asking someone to get you a spare
HMI 1200, given I
stock three different types and a fourth is noted on our spare lamp
page, you might just get the wrong lamp sent to you by someone that knows less than you.
Partial credit but no credit for this lamp. Refine your very expensive lamp a
bit further. “You go back... you not ready to swim with the big fish...” I also say to the techie. Note of course the second version of it in the only time I have ever seen a pre-exploded lamp in this kind of condition. What do you think caused the second “
HMI 1200" lamp to get like this? Bonus points also if you can say the five other description codes for this lamp by other vendors for this same lamp given multi-vapor lamps don’t have
ANSI codes to them thus there is similar lettering but no standardized lamp code.
Last lamp, good also the EVR in the quiz. Very well done!!!
Over all, right on just about all lamps except the scale of
bulb dia. on the double ended ones. If of help, compare their length before becoming a sort of arc lamp
with the EHG in
line with them for
MOL they are most similar to.
After that, very impressive, when are you going to
send an application so I can get an assistant? I’m glad someone took the challenge, everyone should have as it’s but a part for making things work especially lighting guys should be able to figure out. Far too often the writing as to what a lamp is wears off with heat. Than what are you going to do beyond figure it out to make it work?
Missed out in the last lamp as shown in photo's one, two and three. This should be an easy one.
