Flood Lamps

A week or two back I head over to Home Depot for a couple of ordinary PAR38 outdoor flood lamps. They have 90w halogen Philips for $12 a pair and $14 for the GE version. I buy a pair of the Philips and head home to install them.

The other day another lamp burns out. Back to Home Depot. Same store but this time the two pack of Philips are gone replaced some kind of eco (lower wattage, same output) lamps for $20 per pair! I'm not about to do the math on potential savings so I keep looking. I find a pair of Philips compact fluorescent lamps in a PAR38 for $11 per pair. Of course, "warm white" isn't quite the same color temperature as a halogen lamp, not that it's a big deal in an outdoor fixture.

I want to say the eco halogen lamps used 72 watts, the CFL 23 watts, and if I wanted to spend $52 they had an LED lamp that used 19 watts.

When the heck did buying a light bulb get so complicated!

Those incandescent bulbs won't be around much longer, maybe HD is readying for that eventuality.

A while back Congress banned 100 watt incandescent lamps, then after a flood of complaints, pushed back the deadline. Of course, manufacturers tooled down and haven't tooled up so 100 watt lamps can be hard to find. Well, as it turns out, not all 100 watt lamps are banned. Just the ordinary ones. I read something about a company, in South Carolina (I think), that adds an extra filament support and calls them "rough service" bulbs. Made here in America to boot.

After using these CF flood lights, I've noticed a significantly different "throw" (I think that is the correct term) to the light generated. While the lamp appears to be as bright as it's incandescent cousin, the the beam is significantly wider and light intensity over distance drops far more quickly. In other words, the CFL produces a wide, short cone compared to the incandescent.

The other drawback is that the CFL takes a minute or two to reach full intensity. That's not unexpected but I don't think they would be appropriate in a motion sensing, "security" type fixture. In that application, I want the light on full blast immediately.

Yeah, the CFL's, when it's cold outside, take forever to reach maximum brightness. I still use them though.
