Lightbulbs at my house

Lightbulbs at my house

Here are all the different kinds of lightbulbs that I have in lighting fixtures in my house.

21 February 2015: The incandescent light bulb in the green study died, so I replaced it with one of the flat round LED bulbs that my student Arturo gave me a while ago (see previous entry). Although this 10.5W bulb is billed as a 60W replacement, it's as bright as the old 100W incandescent was.

6 April 2014: Arturo Martínez Peguero thoughtfully gave me some of the new Philips flat LED type-A bulbs. I've very successfully replaced the last remaining CFL in the second-floor hallway with one of them (10.5W = 60W replacement). The second-floor hallway is now lit by three generations of Philips LED bulbs. Unfortunately, however, the flat bulb, like the earlier Philips type-A round LED (see previous entry), won't work in the heritage fixture in the front hall; the bulb has a slight flange that prevents it fitting.

30 December 2012: The start-up time for the R-40 CFL in the kitchen has been getting longer and longer. I have replaced it with a new Philips 19.5W LED floodlight marketed as a 120W replacement (1200 lumens -- same as the CFL) for $55!. It is starkly white, and although called a floodlight, it is not as diffuse, making a large bright white patch on the kitchen bench. Will this be usable?

I also bought a pair of 10.5W Philips 60W-replacement LED bulbs ($15) that, unlike the more-expensive 12.W Philips "AmbientLED" 60W-replacement (see prior entry), are not dimmable and are the size and shape of a standard type-A bulb. They are more starkly white and less diffuse than the "AmbientLED", and are dark in the bottom part, making them unsuitable for use in the frosted glass fixture in the front hall. Also, they flicker when on a circuit with a dimmer, even if the dimmer isn't used. So they will replace two nasty CFLs in the bedroom and second-floor hallway, rather than the front hall where the energy saving would have been greater.

9 October 2011: Our first $30 light bulb -- a Philips "AmbientLED™", 12.5W marketed as a 60W replacement, 800 lumens, dimmable, and a life-expectancy of 15 years. (If it fails after just 14 years, Philips will replace it free of charge if I have the cash-register receipt and the barcode from the package.) It's installed in the pulldown fixture over the kitchen table. The light is indistinguishable from the 60W Soft White that it replaced.

October 2010: It seems that R-40 120W incandescent floods are no longer made, which is a problem for lighting in the kitchen. The 60W incandescent R-40 floods that are on sale are only about 900 lumens, compared to 1500 lumens for the present bulbs, and they just aren't bright enough. So I replaced a dead bulb with a Sylvania 23W CFL at 1200 lumens (marketed as a replacement for 75W incandescents) in the downlight fixture. But there are two problems with this kind of bulb:

(1) Such a bulb cannot go in any of the other fixtures in the kitchen, as (unlike the downlight fixture) they do not shade the edge of the bulb. But the bulb itself is clear on the side (unlike the incandescents) and so the tiny bright point of the twisty tube inside is visible. It shines in your eyes, and it's horrible.

(2) Startup time for this bulb is just incredibly long -- two minutes or more, far more than ordinary CFLs. That's barely okay even when it's just one CFL in the room and everything else is incadescent. There's no way this could work if every bulb in the room were like this. You'd have to just keep the lights on permanently. So much for saving energy with CFLs!

22 March 2007: Experiment: Replace one 40W fluorescent in basement with 32W.

10 March 2007: Experiment: In the second floor hallway, replace two of the incandescent 60W bulbs with compact fluorescents -- one regular, one "daylight". Leave one incandescent for comparison.

9 June 2005: New halogen track lights in family room (MR16 floodlight type, 12V 50W); new wall sconce in front vestibule (60W type A); new fixture replaces bare bulb in box room (soon to be office) (100W type A).

15 May 2005: Halogen torchiere in loungeroom replaced with new (safer) incandescent. Takes two 150W A-type bulbs, but right now has 100Ws instead.

15 September 2002: Fluorescent tube over washing machine changed from "warm" to "daylight ultra". The whole room looks different!

19 December 2001. New combination torchiere and reading light for family room has incandescent type-A bulbs in the top part (150W permitted but try 100W for now) and halogen type T-4 in the reading-light part.

24 October 2001. Effective immediately, the bulb in the kitchen pull-down light will be a 60W soft white (A-type) instead of a 60W G-type.

11 September 2000. Effective immediately, the bulbs in the guest bathroom will be 60W instead of 25W.
