About
Light Bulb Coffee is a specialty coffee micro roastery and mobile coffee van serving the people of Swindon and events around the country.
In 2018 Light Bulb Coffee was created. Hi, I'm Donovan Rosema. I care about engaging with people and sharing great coffee. My knowledge, passion and experience in making coffee mean that every cup I make is done with care and attention to quality.
I try to avoid fossil fuels...
- The espresso machine and all the equipment is powered by batteries, not gas - most coffee vans use dual fuel espresso machines which get most of their power from a gas boiler. The van itself is a diesel Fiat Ducato, but ultimately having an electric powered custom built van is the end goal.
- The coffee roasting machine is the Aillio Bullet. It's electric and uses induction technology to heat the drum directly.
Here are some of the advantages of induction:
- Induction eliminates energy waste, transforming the Bullet into one of the world’s greenest roasters.
- Induction drastically increases the responsiveness of the machine, lending it a feel more akin to gas roasters than traditional electric roasters, as any mid-roast adjustments to the power level are instantaneous.
- Induction allows us to pack an incredible amount of heat into the Bullet, reducing its footprint without sacrificing its power, so that I can roast 1kg batches of coffee just about anywhere, with none of the setup headaches associated with gas roasters (almost all coffee roasters use gas powered roasting machines).

I try to recycle and reduce packaging where possible. Currently using Ecocup for our cups, lids, etc.
