Another reason to hate CFLs ...

Arfa Daily · 2010-10-24T01:28:14+00:00

As if any more reasons were needed on top of their horrible startup characteristics, their ugliness, their sick coloured light, and their inability to last for a fraction of the claimed lifetime :-(Like most of us, I suspect, I have hundreds of component drawers, which over the years have become mixed up and confused, so in the circumstances of work being very quiet at the moment, I decided to have a major tidy up and clear out of redundant components. As a first move, I decided to rationalise the resistors, and re-store them by individual value, rather than in groups of values in the same drawer.Now the other day, the bulb in my Anglepoise bench light failed, and as it was the last 60 watt pearl one I had - nowhere stocking such an animal any more due to EU ecobollox intervention - I put in a CFL that had come free in a cornflake packet or some such nonsense. Once it has warmed up in the morning - at least one coffee drinking time needed for this - it seemed to work reasonably well. Until, that is, I started trying to identify the resistors in my old drawers to move them into the individual value drawers in the new location.The spectrum from this lamp is so poor and discontinuous, that it is almost impossible to resolve red from brown from orange, or violet from blue or grey. Absolutely bloody useless. If I can't find any more 60 watt pearl bulbs on the 'net, then I'm going to modify the lampholder to take a low voltage halogen downlighter bulb, and hook it to a 12v transformer.Arfa

Actually, it's to remove any non-refrigerant from the system prior to filling it. Especially any moisture.

Returning to that Philips application note I can only find SOT533 version of BUJ101AU, eg

a power transistor format rather than TO92 format with 1.5A/3A : 400V/700V rating , perhaps for this specific use and known peak/av duty cycle then could be packaged in TO92

Geoff,

One point you missed about my comment on light output is that the lamps were from the same package, bought on the same day. One of them just sat on my shelf for a year.

Best regards, Tim
