The contestants: 5W LED, 7W LED (both Philips), 15W CFL (Megaman)
The blister is just terrible to open…
A real glass dome!
Made in China, what else.
Some info. There’s also a ‘cool white’ version out there. And another one that is dimmable, like its bigger 7W sibling. What pisses me off is that currently I can buy these ‘upgraded’ versions at hardware stores, but they are NOWHERE to be found on any Philips website! Please update more often guys.
Yes, we’re saving energy.
The 7W model:
It is much more suitable for lighting up a place as a single bulb and comparable to a 40W incandescent. The glass dome is not as opaque as on the 5W model. Therefore the internal LEDs mimic the tungsten filament of old fashioned bulbs much better. Without power the LEDs appear as a yellow blob.
|Dimmable||no||yes||4x w. switch|
|Illumination||1/2 shperical||mostly downward||quasi omnidirectional|
|Aging effects||no data||no data||discoloration, slow ‘warming up’|
|Comment||Only good for small places, if used alone.||Mimics incandescent bulbs pretty well||Gets pretty hot|
|Contains mercury||no / negl.||no / negl.||YES|
Why I chose to get rid of the CF bulbs? Here’re my reasons:
- I need ‘Instant-On’ lights
- I don’t like mercury vapour. As I’m clumsy, I might break one.
- My CFL made ‘ugly light’. Sorry, I don’t have a spectrometer at hand.
- The older my CFLs get, the longer they need to ‘warm up’
Put one of these in your hallway and what you instantly see is: DARKNESS. Before they’ve managed to come up to full brightness, you’re out of it again. Because of that I’ve got used to leaving the CF bulb in my hallway on all the time, which defies the whole purpose of ‘energy saving’. I need ‘instant on’ in these places. The same goes for my kitchen and bathroom as well.
Comparison 5W Philips vs. 15W CFL:
My camera’s exposure settings were locked to the left bulb (5W LED). It is obvious that a 5W LED (250 lumen) can’t compete with a 15W CFL (800 lumen) face to face. The LED bulb’s glass cover is truly opaque, whereas the CFL has a plastic shell with a silicone cover that creates a ‘frosting’ effect. Therefore the internal structure of the CFL is visible as ‘hot spots’ in brightness.
Comparison 5W / 7W Philips vs. 15W CFL:
Initially the CFL is the dimmest of the three (right).
After 5 minutes the CFL has finally reached its maximum brightness, followed by the 7W bulb (left bottom) and the 5W bulb (left top).
The 5W bulb is tolerable for places that are only lit up from time to time (hallway, storage …) and you don’t plan to do any reading or living in. It’s good for additional lighting, for setting visible accents and so forth, but not as the primary source of light.
The 7W bulb is more like it and is comparable to a 40W incandescent one. Used in a 5x chandelier it easily lights up a small living room. As the light is emitted mostly downwards (2-pi emitter) putting it above a table is a good idea.
I’ll keep my CFLs as long as they are in good condition, but I will _definitely not_ buy any new ones. They’ll be replaced by LED bulbs once they start emitting ‘terrible light’.
Death to CFL bulbs!
So long… and thanks for all the fish!
