Why use them at all?
LED lamps are super bright, can be selected by a range of Kelvin outputs, from 3,000 (a "warm" light) 4,500 (akin to an incandescent bulb) and 7,000 (a bright white). LEDs also use far less energy, typically only one ninth of the power demand of an incandescent of the same lumens output, or only half the power demand of a fluorescent.

All fluorescent tubes, whatever their shape and size, use mercury vapour to create ultra-violet radiation. The coating on the inside of the tube then fluoresces to create a lower wavelength white light.
The problem of broken and discarded fluorescent tubes goes back over 90 years. It's nothing new. Maybe Donald himself is fluorescing?

@Petter CFLs are still on the market, and sometimes are cheaper to buy. LED prices have come down a lot, but I'm not sure they're low enough to get CFLs off the market.

I think ou're right about the improper disposal. Thankfully the big box stores, Lowe's and Home Depot will dispose of them properly for you but I'm sure most people don't bother.

I have switched 90% of my bulbs to LED. I'm looking forward to a requirement for LEDs myself,accompanied by education and strict requirements for CFL disposal.

@bingst
I am an LED fan. Even when they were really expensive I fitted my personal office with them 20 years ago, and gradually fitted them throughout my business premises. (I could claim them against tax, of course!)
Nowadays, here in Spain I buy LED bulbs for between 2.00 to 4.0 euros (($2.40 to $4.75) depending on type and rating. A typicall 7.5watt (75 watt equivalent light output) costs €2.75 in a local shop.
My entire, large house (34 bulbs total) has used LEDs for the past 3 years. I have had to change 3 bulbs in that time. One bulb a year among 34 bulbs.
There's no economic argument possible against that!

@Petter I think LEDs are a great advancement. I had thoughts of using them as lighting before they were available as such! lol Unless the US government bans the manufacture and import of CFLs, I think they'll be on the market for years to come.

@bingst Until gradually falling demand pushes up manufacturing costs and therefore their price, at which point there should be a rapid drop. An example is digital cameras. I bought my first one on 1992. It was pretty crappy, but it gave me instantly usable black and white photos for my magazine, thus giving me a competitive edge over traditional photography rivals. Film continued to sell well for many more years, as digital slowly ate into the market, then it reached a tipping point and in only a few years previously expensive cameras were turning up in junk sales and film was only available in specialist shops.
