You don’t wan’t Mercury accumulating where you habitate,so far iv’e broken four CFLs through common mishaps(they break easily).
I know it’s a small amount,but it will accumulate and it is definitly hazardous.There is recommended proceedure,you have to clean this without (further contamination)making it airbourne or spreading it all over.You can argue It’s a miniscule amount but there are already dozens of mercury sources and should we all be eagerly bringing more into our homes?
Tried out a lower watt bulb Ace had and loved the spectrum so I’m determined to get at least the most used lamps retrofitted.I think 30 fixtures around my house although daily about seven might light so I have to have lets say three 13w/100w and the remainder 7w/60w … needless to say the price has to get lower before the whole house would be equiped.
But eventually . . . .

The big advantage of LEDs over all fluorescent technologies in the home environment is that they are not sensitive to being cycled dozens of times per day. Fluorescents work well in offices and factories where they can be turned on once and left on for hours, but more than about five cycles per day tends to be very hard on them.

A secondary advantage over at least the current crop of CFLs in particular is that LEDs are not particularly sensitive to orientation. In our home the majority of the lighting is provided by base-up bulbs; while CFLs are available in that configuration, they are not the norm. One set of track lights in particular can reliably cook the ballast of a CFL in about a month of normal use; we’ve given up for now and returned to incandescents for that application until the price of LEDs comes down a bit further.

In any event, we have almost certainly bought the last fluorescents that we will ever need for our house. The few that we have in stock will tide us over for a year or so; all new purchases will be LED unless an even better technology comes down the pike.

I just bought a set of these globe leds (in warm white)
The good :
- the light distribution is very acceptable (240° round)
- the oil conducts the heat very well and the result is a cool lamp.
- they are plexy (don’t think it would break eassily)
The bad:
- the led they used, it is a single UV led, directly driven by 220V. The problem is that the light emitted is yellow to green, a typical production fault caused by the wrong doping of phosphor material on UV led (see wikipedia EN for explanation)
- because of this production fault the amount of visible light is much lower than expected.
Conclusion:
If they give some guarantee about the colour, or correction of this issue, they might very well become usefull. Until than they are absolutely unusable.
For this price I would have expected at least some quality leds….

I have having a safe alternative to CFLs. Some people don’t want to go there because they’ve hard one of two horror stories about mercury poisoning.

Yea, these bulbs are really neat, we’re just starting to sell them at our LED light retailer. LED technology just gets better and better!

A correction, though: Infinice mentions that CFLs use 25% of the energy that incandescents do, but I think it’s more like 10%. And LEDs use as little as half the power that fluorescents do. So both kinds of bulbs are significantly more efficient than incandescents.

Another correction: the power consumption of this bulb is 4 Watts, not 25. I think the 25W is just an expression of the brightness. (Since we’re used to using incandescent bulbs, brightness tends to be expressed in watts, which is equal to power consumption in incandescents, but not in CFLs or LEDs.) You want to look at the lumens for a measure of brightness, and this kind of bulb is certainly available with a higher lumens rating than 200.

Anyone have a simple payback calculator for comparing lifetime operating costs of incandescents vs CFLs vs LEDs? Unless these bulbs are like $15 each, I don’t see their advantage over CFLs when used conservatively. The real draw is in situations where you don’t want to constantly change out bulbs, or when the lights are operating continuously. Putting one of these in a desklamp doesn’t seem to be the best application.

Could you make each bulb like a lava lamp?

The liquid barely gets just barely warm to the touch. Here’s some tests from our lab:
After running for 1 hour:
Incandescent: 335 deg. F, 135 deg. C
HydraLux-4: 87 deg. F, 31 deg. C

If the bulb breaks, the liquid inside is completely harmless – similar in composition to baby oil. Just wipe it up with a cloth/soap.

I like the idea of these bulbs but I would be concerned about them being liquid filled. How hot would the liquid get and what if the bulb broke?
