I have a piano lamp I like very much. It takes 4 15W candelabra bulbs like these:

http://www.lampsplus.com/products/4-pack-15-watt-clear-candelabra-tube-light-bulbs__39869.html

And when all 4 are loaded up - they have a half life of a mayfly. They are rated for 2000 hours. And I have to say if they are right, life is passing me by very quickly. Removing all but one makes the remaining one last a very long time, which makes me think all 4 are too hot for the fixture.

Does anybody know if there is a replacement bulb that is LED (and uses the same base) which would run a lot cooler? Or do I suffer the $15 per 2 months until I can afford one of these?

You might check this out.

With the mini-tubulars, you will need to be careful when checking them out to find the proper diameter of the envelope to fit your lamp.

Good Luck.

it certainly sounds like an application for LEDs. However, LEDs, while giving off much less heat than an incandescent, also don't like hot environments, so they're not the best fit for an enclosed lamp shade or other situations where heat will get trapped. You don't mention if the lamp needs the slim bulbs shown in your link, or wether there's a little more wiggle room. As you can see from the link from MM - most of the LED bulbs are a little bigger than traditional incandescents. They are also generally noticeably heavier and much more directional, so orientation is more important. While there is a decent selection of bulbs in the site linked by MM - there is one critical piece of information missing from all of the bulb descriptions - lumens. I wouldn't buy any bulb today that doesn't have this as as standard part of the description. (I believe in an increasing number of jurisdictions that this is becoming law).

On the LED lamp linked by the OP - I've seen some reviews of similar lamps that indicate that not all of these are as well endowed with LEDs as the size and shape would suggest. I don't recall which brands are better than others, but it's worth checking how many LEDs and the total light output and the coverage area before laying down the cash!

Thanks guys - M Marty - the widths are too large (0.7") mine is less than a half inch. :-(

Lumens I don't need as much as it appears a single 15W is enough for me. I'll keep looking.

Or... should I start a new business? Let's see, hundreds of piano players times 4 bulbs and at least 10% of these players have a piano light. We're talking a huge market of some 160 to 200 bulbs a year! I'm counting my profits already.

Best LED light is a House Of Troy #GPLED26 More stable, twice the wattage,extra length and height and low to no heat! Teachers love this light.
All the best!

you might also check out Conoco piano lamps. Similar design to the HoT LED lamp, but gets better reviews on Amazon and seems to be more adjustable. Also a little cheaper which isn't a bad thing.

You can also try compact floresents. They run much cooler if you can get one small enough.

Thanks for all the suggestions. Alas nothing is small enough. I'll stick with the 4x$4 bulbs that last for a couple of months for the near future. Until I win the lottery.

I also was burning out incandescents frequently. The I found a "curly" 13W cfl (60W equiv) that fit and now no more burnouts.

Malkin,

The OP is asking about a thin diameter, tublar envelope, candelabra base, lamp. None of those fit the bill as they will not fit in the confined space of the lamp housing of the fixture. An equivalent LED does not seem to exist. Flourescent is totally out of the question for the same reasons. Please read the size restrictions as stated by the OP.

Indeed Minnesota Marty is right. The total diameter must be less than or equal to 1/2". With a candelabra compatible screw base.

I think that you are going to get a lamp made with LEDs. But I would never get a lamp that attaches to a music desk. I have seen too much damage to music desks from lamps like that.

Not an LED, but it is teeny and cheap.

Kind of cute to my way of thinking.

Malkin,

And you accuse me of being obsessed?

BTW - your "teeny and cheap" lamp is for use at 18v.

Poof!

Grotriman,

Sounds like you may have a lamp similar to this? I have one of these I sometimes use on the organ console at church. I can confirm your experience: no LED substitutes, only that one bulb will work, and they are expensive.

They also come loose quite easily and must be tightened often. But you have to do it before you turn it on because the bulbs get searingly hot within milliseconds. In fact, I suspect that is why they do not last long. I did find some bulbs locally, but they were not cheap. In fact, I think I paid considerably more than $15.99 for 4.

When shopping for a lamp for my piano at home, I bought a Koncept Z Bar. Not cheap, but at least it has LEDs.

Yup! That's the one. And yes - they come unscrewed spontaneously! I thought it was only when I played Chopin and the lamp wanted more romantic lighting (self dimming).

I'll end up re-wiring the thing for a different kind of bulb eventually. I'll let you know how that turns out. The 15W per bulb is very problematic as it is definitely too hot and I really don't need 60W total of light on my two pages of piano music (also casts a harsh shadow on the keyboard).

Update - I found a source for these bulbs, relatively inexpensive at $1.28 for 10 or more, and also in a 6W version rather than the 15W. I'm working on the theory that less heat will make them last longer. (stock # B708106)

Added side benefit is that they cast a dimmer more yellow light in the same manner as Chopin's candles would have provided. Thus adding some more realism to my playing.

I'll let you know how long they last.

Here's another thought-filaments in light bulbs are rated for a certain power level--in your case that would probably be 110-120 volts--but an increase in the power supply (not controllable by you, its your power company) will decrease the life of the filament drastically.(Bulb manufacturers acknowledge that a 10% increase can amount to a 50% shorter life --this info from having operated a lighting store and dealing with lamp manufacturers) Get someone (qualified) to measure how much power is being supplied from the socket (using a multimeter) and you can bet you'll be getting oversupplied. If you can't find lamps that are rated at a little higher tolerance, maybe try a British or European lamp at 220volts but at a higher wattage like 25 watts---it'll glow dimmer, but will last a lot longer because its filament is not being "pushed".
Good luck.

Maybe you can use a dimmer and reduce its intensity just a little. As yamahanut says, a little reduction in brightness will give you a huge gain in lifetime and temperature.
If temp is really the issue, maybe it is also possible to improve the ventilation?

I live in New York City where the power is 1) on and steady or 2) off. I haven't seen any issues with surges or variability (I do have a lot of equipment that needs a steady supply).

I think the lower wattage will decrease the heat and increase the life. Let's see.

The fact that they loosen themselves makes me think it may be the vibration from your playing that's killing off the bulbs off rather than the heat they generate. We've had a similar problem with chandelier bulbs in ceiling fan fixtures. We run our fans continuously. The bulbs seem to last a good bit longer in immobile fixtures.

I will switch to soft music for a year and see if they last longer. After I play for a year as I currently do to test the wattage. Then I should have enough saved up for the LED version!
