What I am trying to obtain is bayonet style clear glass light bulb of equivalent to the old 150w. It must be clear and bright to shine through dark lead light shade.I have tried the local hardware shops but nothing bright enough leaving the room quite dark. thank you

Suggest you go to specialist lighting company and explain prob. Surely they can at least advise you. Capricorngirl
What you want is Bright white, not warm white which is the yellowish ones. Cheap.
Mitre 10 actually have a good range of styles. but remember, Bright White.

Depends on what you taste is, personally i and many others, can not stand the cold look of bright/vivid/pure/cool white or daylight colour, and vastly prefer warm white, which is close to the same colour as the old incandescent ones, which "imo", adds a so much warmer feel to the room.
Those charts are way out of date, or they are based on very poor quality LEDs.
The output of LEDs should be a minimum of 90-100lm/W, otherwise they are very poor quality.

Yes true, for quality brands a 100 watt equivalent (1600 lumen)is often 16 -18 watts now, not the 25 they say, but it does give the lumen of the old incandescent to work from when choosing. Personally i find packaging on some lamps, tends to overstate what they are equivalent too, i used 14 watt phillips (1400 lumen) as replacements in most of my fittings, but do not think they are as bright as the old 100's, so thinking of changing some to 18's now. I have had my 36 watt in kitchen a while, which seemed great at first, but i am still tempted to upgrade to the 45 watt one now. I do see most decrease in efficiency at higher wattage levels though. I see the newer 14.5w phillips is now up to 1560 lumen, so a good 100 watt replacement now.(but do not believe its statement as a 120 watt equivalent)

My brother is legally blind, he sees a bit but not much. My mum has retinopathy and husband has a brain issue and hence only sight from one eye. I can tell you bright white is easier for vision than yellow. I had to change some to accommodate them. It's not a personal taste thing. It's brighter.

Bright white is simply a "cleaner" more pure light. Yes I have similar problems in that area, Hate those soft white lights in most area's. I use 1440's in my office but place them outside of direct vision from where I sit.
